The MdiTabDragManager is used by the to manage a tab drag operation. The drag manager is created by the via the and handles the initiation and processing of the tab repositioning.

The MdiTabDragManager behaves differently than the base TabManager. It mimics the drag behavior displayed by Visual Studio when repositioning tabs in a tab group. When a tab is dragged within its tab group, it is immediately repositioned within the collection but the corresponding move events are not invoked during the drag operation. If the drag operation is cancelled, the tab is returned to its original position. When the drag operation is completed the tab is repositioned if needed or the drag context menu is displayed. The drag behavior differs slightly in that scrolling is supported when dragging near the inner edges of the tab group that contains the tab being dragged.

The MdiTabGroupSettings object is used to affect the appearance and behavior of instances. The values of each property are initialized with default values. These default values are resolved by a instance that may be accessed from the group's property.

The most commonly used properties are the TabStyle and TabSizing. The property is used to determine the look and feel of the tab items and affects the shape of the tab item borders. The property determines how the size of the tab items is calculated. By default, tab items are sized based on the amount of space required to display the tab's image and text. The size may be constrained using the and to ensure that the tab items are always within a reasonable size.

The class exposes several appearance properties that can be used to affect the appearance of the tab area (the area behind the tab items), scroll related items, tab list and close buttons. The tab area may be modified using the . The scroll items can be modified using the (scroll thumb and track and the , which affects the scroll buttons and scroll thumb appearance. The will affect the appearance of the close button (displayed as an "X" in the tab group area). The will affect the appearance of the tab list button (displayed as a downward arrow indicator in the tab group area).

Several properties for manipulating the layout of the tab items are available in this class. The determines the area in which the tab items will be displayed. By default, the tab items are located on the top and positioned from left to right. This property may be used to position the items on the left, right or bottom. The is used to determine how the text of the tab is displayed with respect to the orientation of the tabs. may be used to adjust the amount of space between the contents of the tab and the borders.

The class also has several properties to determine how and when scroll related items are displayed. The most commonly used of these are the and .

 Returns or sets whether an from a different MdiTabGroup may be repositioned to the

By default, tabs from any may be repositioned within their current or in other tab groups. The property is used to limit where a tab may be dragged to or whether an MdiTab may even be dragged. The AllowDrop property can be used to limit which tabs may be moved into a particular tab group. Setting this property to false will prevent tabs from other MdiTabGroup instances from being added to the tab group's collection.

 Returns or sets whether the will be automatically selected after hovering over the tab.

By default, AutoSelect resolves to false. When set to true and the mouse is within the bounds of a tab for the interval, the tab is automatically selected.

 Returns or sets whether separators will be displayed between button style tabs.

When the is resolved to StateButtons, the tabs are displayed as state buttons where the selected tab is in the pressed state. By default, there is some space between the state button tabs which can be controlled using the .

 Returns or sets the amount of space between tabs.

The InterTabSpacing determines the amount of space between the tab items. When set to a negative value, the tab items overlap. When set to a positive value, the specified amount of pixels is left between the tab items. When left at the default value, the space between the tabs is resolved differently based on other settings, such as the . For example, the default InterTabSpacing for Excel style tabs is -8 to allow the tab items to overlap as they do when using Microsoft Excel.

Note: If the is less than 0, then all tab items must be at least the absolute value of the InterTabSpacing.

 Returns or sets the height for the objects.

The TabHeight controls the logical height of the tab items. By default, the TabHeight is based on the size needed to show the image and text completely within the borders for the tab item, which is affected by many property settings (e.g. , , etc). For tabs displayed on the top or bottom, the TabHeight affects the displayed height of the control while it affects the displayed width of the tabs when the is such that the tabs are displayed on the left or right.

 Returns or sets the maximum width for the objects.

The MinTabWidth and MaxTabWidth properties determine the minimum and maximum extents of the tab items respectively. By default, the minimum tab width is based on the width required for the borders and there is no maximum tab width.

 Returns or sets the number of instances visible at a time when the 'TabStyle' is set to TabsPerRow.

The TabsPerRow property is only used when the resolves to TabsPerRow. When that style is used, this property determines the number of fully visible tabs that will equally share the available tab area. For example, if there is 100 pixels of available area and TabsPerRow is set to 4, each tab will have a logical width of 25 pixels.

Note: A value of 0 will be treated the same as -1 indicating that the value has not been set.

 Returns or sets the style of button used to display the scroll and close buttons. Returns or sets the style of button used to display a state button style tab item.

When the is resolved to StateButtons, the tabs are displayed as state buttons where the selected tab is in the pressed state. The TabButtonStyle determines the style of buttons displayed including the tab border style.

 Returns or sets the style of scroll buttons displayed.

The ScrollArrowStyle determines the display of the arrows in the first/last, next/previous and next page / previous page buttons. The property is used to determine which scroll buttons should be displayed. The property determines when scroll buttons should be displayed. If scroll buttons are set to always be displayed, they will appear disabled when no scrolling can occur. The WindowsXP style uses the Windows Xp style chevrons seen in the spin and scroll buttons. The Standard and VisualStudio settings are displayed as triangles indicating the direction of the scroll. The difference being that VisualStudio style scroll arrows are not filled when they are disabled as they appear in Visual Studio .Net.

 Returns or sets whether scroll buttons will be displayed.

The ScrollButtons property is used to determine if and when scroll buttons should be displayed. By default, scroll buttons are only displayed when there isn't enough room to display all the tab items. The size of the tab items is based on multiple factors including the , , and properties.

 Returns or sets the types of scroll buttons to display.

ScrollButtonTypes is a flag type enumeration (multiple values may be combined using an OR operator) that determines which scroll buttons are displayed. When the scroll buttons are displayed is based on the property.

This is similar to a scroll bar without any scroll buttons. Returns or sets the orientation of the tabs in the

The TabOrientation property determines the alignment and order in which the tabs are layed out. By default, the value resolves to TopLeft which means that the tabs are aligned on the top and are laid out from left to right.

 Returns or sets how the tab text is aligned.

The TextOrientation determines the orientation of the text in the tab. The orientation may be specified relative to the or to an absolute value. By default, the text orientation is resolved based on the resolved TabOrientation to keep the text parallel with the tab orientation.

 Returns or sets the amount of padding around the image and text of the .

TabPadding is the amount of space between the contents of the tab (the image and text) and the borders of the tab.

The Width and Height may be set on different levels. In other words, you may set the Width of the TabPadding of the to 3 but leave the Height set to -1 and the Height of the TabPadding will be used if specified.

 Returns or sets the sizing mode used to display the tab items.

TabSizing determines how the size of the tab items are calculated.

AutoSizeThe tab size is based on the size required to show the image and text. FixedThe tab size is based on the if resolved to a value, otherwise the AutoSize value is used. JustifiedThis sizing mode only affects the tabs when there is not enough room to display all the tab items. Each tab item's size is reduced so that all the tab items are in view. SizeToFitIncreases or decreases the size of the tab so that they occupy the entire available area. CompressThe non selected tabs are sized to just enough space to display the associated image. The selected tab is sized based on the largest image and text area. TabsPerRowThe size of each tab is a percentage of the available area based on the setting. Returns or sets the style of tabs displayed.

Determines the display style for the tab items. The default resolved value is VisualStudio so that the tabs appear as the mdi tabs appear in Visual Studio .Net.

 Returns or sets the extent for the scroll track.

ScrollTrackExtent is the width of the scroll track used to navigate between the tab items. The scroll track is only displayed when the Thumb enum is included in the property. The property is used to determine when the scroll buttons should be displayed. By default, they are only displayed when there isn't enough room to display all the tab items.

 Internal property. This property is used internally as a workaround for a serialization bug in Visual Studio that was introduced in version 1.1. Returns or sets the amount of space between the edge of the tab group and the tabs and scroll buttons. Determines the minimum amount of space in the visible area after the tabs. If this property is set to a number less than 0 then an ArgumentOutOfRangeException is thrown. Determines the amount of space in the visible area before the tabs. If this property is set to a number less than 0 then an ArgumentOutOfRangeException is thrown. Gets or sets the location of close buttons within the tab group.

When is set to true, the AutoSelectDelay determines the interval that the mouse must be over the tab before it is automatically selected. By default, AutoSelect is not enabled.

 Readonly. Returns the amount of space between tabs.

The InterTabSpacing determines the amount of space between the tab items. When set to a negative value, the tab items overlap. When set to a positive value, the specified amount of pixels is left between the tab items. When left at the default value, the space between the tabs is resolved differently based on other settings, such as the . For example, the default InterTabSpacing for Excel style tabs is -8 to allow the tab items to overlap as they do when using Microsoft Excel.

Note: If the is less than 0, then all tab items must be at least the absolute value of the InterTabSpacing.

 Readonly. Returns the maximum tab width for the objects.

The MinTabWidth and MaxTabWidth properties determine the minimum and maximum extents of the tab items respectively. By default, the minimum tab width is based on the width required for the borders and there is no maximum tab width.

 ReadOnly. Returns the extent for the scroll track displayed between the scroll buttons

ScrollTrackExtent is the width of the scroll track used to navigate between the tab items. The scroll track is only displayed when the Thumb enum is included in the property. The property is used to determine when the scroll buttons should be displayed. By default, they are only displayed when there isn't enough room to display all the tab items.

 Readonly. Returns the height for the objects.

The TabHeight controls the logical height of the tab items. By default, the TabHeight is based on the size needed to show the image and text completely within the borders for the tab item, which is affected by many property settings (e.g. , , etc). For tabs displayed on the top or bottom, the TabHeight affects the displayed height of the control while it affects the displayed width of the tabs when the is such that the tabs are displayed on the left or right.

 Readonly. Returns the number of instances visible at a time when the 'TabStyle' is set to TabsPerRow.

The TabsPerRow property is only used when the resolves to TabsPerRow. When that style is used, this property determines the number of fully visible tabs that will equally share the available tab area. For example, if there is 100 pixels of available area and TabsPerRow is set to 4, each tab will have a logical width of 25 pixels.

 Readonly. Returns the style of button used to display the scroll and close buttons. Readonly. Returns the style of button used to display a state button style tab item.

When the is resolved to StateButtons, the tabs are displayed as state buttons where the selected tab is in the pressed state. The TabButtonStyle determines the style of buttons displayed including the tab border style.

 Readonly. Returns the style of scroll buttons displayed.

The ScrollArrowStyle determines the display of the arrows in the first/last, next/previous and next page / previous page buttons. The property is used to determine which scroll buttons should be displayed. The property determines when scroll buttons should be displayed. If scroll buttons are set to always be displayed, they will appear disabled when no scrolling can occur. The WindowsXP style uses the Windows Xp style chevrons seen in the spin and scroll buttons. The Standard and VisualStudio settings are displayed as triangles indicating the direction of the scroll. The difference being that VisualStudio style scroll arrows are not filled when they are disabled as they appear in Visual Studio .Net.

 Readonly. Returns whether scroll buttons will be displayed.

The ScrollButtons property is used to determine if and when scroll buttons should be displayed. By default, scroll buttons are only displayed when there isn't enough room to display all the tab items. The size of the tab items is based on multiple factors including the , , and properties.

 ReadOnly. Returns the types of scroll buttons to display.

ScrollButtonTypes is a flag type enumeration (multiple values may be combined using an OR operator) that determines which scroll buttons are displayed. When the scroll buttons are displayed is based on the property.

This is similar to a scroll bar without any scroll buttons. Readonly. Returns the orientation of the tabs in the

The TabOrientation property determines the alignment and order in which the tabs are layed out. By default, the value resolves to TopLeft which means that the tabs are aligned on the top and are laid out from left to right.

 Readonly. Indicates how the tab text is aligned.

The TextOrientation determines the orientation of the text in the tab. The orientation may be specified relative to the or to an absolute value. By default, the text orientation is resolved based on the resolved TabOrientation to keep the text parallel with the tab orientation.

 Readonly. Returns the amount of padding around the image and text of the .

TabPadding is the amount of space between the contents of the tab (the image and text) and the borders of the tab.

The Width and Height may be set on different levels. In other words, you may set the Width of the TabPadding of the to 3 but leave the Height set to -1 and the Height of the TabPadding will be used if specified.

 ReadOnly. Returns the resolved tab sizing mode used to display the tab items.

TabSizing determines how the size of the tab items are calculated.

AutoSizeThe tab size is based on the size required to show the image and text. FixedThe tab size is based on the if resolved to a value, otherwise the AutoSize value is used. JustifiedThis sizing mode only affects the tabs when there is not enough room to display all the tab items. Each tab item's size is reduced so that all the tab items are in view. SizeToFitIncreases or decreases the size of the tab so that they occupy the entire available area. CompressThe non selected tabs are sized to just enough space to display the associated image. The selected tab is sized based on the largest image and text area. TabsPerRowThe size of each tab is a percentage of the available area based on the setting. ReadOnly. Returns the resolved tab style used to display the tab items.

Determines the display style for the tab items. The default resolved value is VisualStudio so that the tabs appear as the mdi tabs appear in Visual Studio .Net.

The MdiTabSettings object is used to affect the appearance and behavior of an object. The values are initialized with default values. These default values are resolved by a instance that may be accessed from the MdiTab using the property.

The most commonly used properties of the class are the appearance properties. These properties are used to control the look of the tab items. The class exposes 4 tab appearances. The property is used to determine the default appearance for the tab. Usually the Image property is set on this property so that a particular image is displayed for a tab regardless of its state. The is used to augment the appearance of the tab when it is the in its containing . When the tab is not selected, the values on this appearance are not used. The is similar to that of the SelectedTabAppearance in that the tab must be selected. However, just as there can be only one active mdi child, there is only one . If there is only one tab group, then the active tab will be the selected tab since the active tab must be selected. However, when there is more than one tab group in the collection, only one tab group will contain the active tab. The appearance of that active tab will be affected by the ActiveTabAppearance. The last appearance property is the . This appearance is used in the appearance resolution process when the mouse is over the tab item if the property resolves to true.

The class contains several properties that affect the behavior of the tab. The property is used to determine whether a tab may be repositioned and to where. The determines whether the close button is enabled when the tab is selected while the determines the action that will be taken when the tab is closed.

Note: Only the font information for the tab appearances of the and are used to determine the size of the tab items. The font information set on the will affect the display but will not be used to determine the size of the .

The UltraTabbedMdiManager provides a Visual Studio .Net style tabbed interface. Each mdi in the of the is represented by a tab.

An instance is created for each mdi child form and provides the information for the display of the tab. By default the text displayed in the tab item is based on the text of the associated but can be overriden using the property. Also, the form's icon may be displayed in the tab using the property.

The MdiTab objects for visible forms are moved into an when they are displayed and may be repositioned to other or to a new MdiTabGroup (). MdiTab objects whose associated forms are not visible are maintained in the collection. When a hidden form/tab is made visible, the event is invoked when the tab is about to displayed.

The is used to set default values for the appearance and behavior of the objects. The values can then be overriden by the containing using the and can be further controlled at the specific tab using its . The appearances (e.g. ) of the is used to control the colors and images displayed by the tab items. Similarly, the is used to set the default values for all the . These values can be overriden for specific objects using the property. The TabGroupSettings property is useful to initialize the and as well as other appearance settings.

 Returns or sets the ImageList providing the images for the component.

When an ImageList has been assigned, the property of the various tab appearances (, , etc.) may be set to an integer value indicating the index of the image in the ImageList. Alternatively, tabs can display the of the associated using the property.

 Returns the instance representing the current of the

The ActiveTab is the object representing the of the . You can access the tabs for specific objects using the method.

Since the ActiveTab represents the active mdi tab and mdi child form activation is maintained by their zorder, the ActiveTab must be the of its . Since the ActiveTab must be selected, as the ActiveTab changes, the event will be invoked.

Note: The event may not always be cancellable since the activation may occur as a result of an external action - e.g. when the mdi child is first created.

 Returns an instance used to control the default settings for the objects. Indicates whether an object has been created. Returns True when the MdiTabSettings object for the property has been created.

Use this property to determine if an object has been created. MdiTabGroupSettings objects in general are not created until the properties associated with them are accessed.

 Returns a collection of instances

MdiTabGroup objects are created and destroyed as needed. When all of the objects in a tab group's collection have been closed, hidden or moved to other tab groups, the tab group is removed from the collection and released. When there are no tab groups and a tab is being displayed or when a tab is explicitly moved to a new tab group (e.g. using the method), a new MdiTabGroup is created and the event is invoked to allow the tab group settings to be initialized.

Note: When an MdiTabGroup that contains child MdiTabGroups in its only has 1 MdiTabGroup, the children of that tab group are promoted and the tab group that contained only the single child tab group is removed.

 Indicates if the collection has been created and contains at least one instance Returns or sets whether the end user may create horizontally oriented tab groups.

The property determines how the objects in the collection are laid out. When there is only 1 tab group and the is greater than 1, the end user may create either a Horizontal or Vertical tab group by either dragging a tab near the edges of the mdi client or using the context menu. Setting the AllowHorizontalTabGroups to false (true is the default value), will prevent the user from being able to create a horizontal tab group. Also, if this property is set to false, the user will not be able to create additional horizontal tab groups.

Note: This property only affects the ability to create horizontal root tab groups. When true and is true and the Orientation is vertical, dragging and releasing a tab within a few pixels of the outside top or bottom mdi client edge will create a new tab group for the tab and another that will be used to nest the tabgroups that existed in the collection. The orientation will then be toggled to horizontal.

 Returns or sets whether the end user may create vertically oriented tab groups.

The property determines how the objects in the collection are laid out. When there is only 1 tab group and the is greater than 1, the end user may create either a Horizontal or Vertical tab group by either dragging a tab near the edges of the mdi client or using the context menu. Setting the AllowVerticalTabGroups to false (true is the default value), will prevent the user from being able to create a horizontal tab group. Also, if this property is set to false, the user will not be able to create additional vertical tab groups.

Note: This property only affects the ability to create vertical root tab groups. When true and is true and the Orientation is horizontal, dragging and releasing a tab within a few pixels outside of the left or right mdi client edge will create a new tab group for the tab and another that will be used to nest the tabgroups that existed in the collection. The orientation will then be toggled to vertical.

 Returns or sets whether the end user may create nested groups.

By default, AllowNestedTabGroups resolves to false. When this property resolves to true, the end user may drag tabs (depending upon their ) to create nested tab groups. A nested tab group is an that contains MdiTabGroups instead of directly containing instances. Nested tab groups allow for more control over the layout of the tabs.

 Indicates if the end-user can create nested tab groups. Returns or sets whether tooltips are displayed.

By default, ShowToolTips is true. When true, tooltips are displayed for tabs and buttons (scroll buttons and close button). Tooltips are only displayed for tabs when either the property is set or there is not enough room to display the for the tab.

 Returns or sets whether the control interprets an ampersand character (&) in the MdiTabs property to be an access key prefix character.

By default, ampersands are not interpretted as mnemonic characters. When set to true, pressing Alt and the mnemonic character (the character following the &) will activate the associated form.

 Returns or sets the orientation of the tab groups.

The Orientation determines how the are laid out. The tab groups are either displayed with a Horizontal split and laid out from top to bottom or they are displayed with a Vertical split and laid out from left to right. When there is only 1 in the collection, the end user may create a new MdiTabGroup in either orientation unless the or is set to false.

The Orientation may also be changed programatically to switch between the layout styles. This will affect the of tab groups in the collection since the sum of the extents must match the extent of the relative client area. In other words, when the Orientation is set to Horizontal, the sum of the extents must equal the height of the client size of the mdi client. If this is not the case, the tab groups are resized proportionally based on their current extents to adjust for the difference.

 Returns or sets the border style for the splitter bars.

The SplitterBorderStyle determines the style of the border for the splitter bar displayed between instances. Each MdiTabGroup except the last item in the will have a splitter that can be used by the end user to modify the of the tab group. Depending upon the of the tab groups, the splitter will be displayed either vertically or horizontally. When the Orientation is set to horizontal, the splitter bar is displayed horizontally and displays the top and bottom borders using the SplitterBorderStyle.

Note: The SplitterBorderStyle does not affect the width of the splitter so the must be wide enough to accomodate the SplitterBorderStyle.

 Returns the resolved borderstyle used to display the splitter bars.

The SplitterBorderStyle determines the style of the border for the splitter bar displayed between instances. Each MdiTabGroup except the last item in the will have a splitter that can be used by the end user to modify the of the tab group. Depending upon the of the tab groups, the splitter will be displayed either vertically or horizontally. When the Orientation is set to horizontal, the splitter bar is displayed horizontally and displays the top and bottom borders using the SplitterBorderStyle.

Note: The SplitterBorderStyle does not affect the width of the splitter so the must be wide enough to accomodate the SplitterBorderStyle.

 Returns or sets the maximum number of instances that may be created.

The MaxTabGroups determines the maximum number of objects that contain object can be created.

Note: This limitation is imposed both programatically and via the ui. In other words, the options to move a tab to a "New Horizontal Tab Group" or "New Vertical Tab Group" will not be included in the context menu if there are already the MaxTabGroups number of MdiTabGroup objects (in the collection or within the of nested MdiTabGroups) with objects in their collection. Also, an exception will be raised if an attempt to programmatically move a tab to a new tab group (e.g. ) is made.

 Returns or sets the width of the splitter bar displayed between tab groups.

The SplitterWidth determines the width of the splitter bar in a tab group. All objects in the collection have a splitter bar except the last one. The splitter bar is used by the end user to modify the of a tab group.

When the user presses the logical left mouse button on the splitter bar, the event is invoked to determine whether to allow the splitter bar to be repositioned. If the event is not cancelled, the user may move the splitter bar. Once the splitter bar is released, the is updated (as well as that of the adjacent tab group) and the event is invoked.

 Returns or sets the size of the images in the tabs.

The ImageSize property determines the size of the image displayed in an . All tab images are scaled using this property. The default value is 16x16.

 Gets/sets the color displayed as transparent in a image.

When set to a color other than Color.Transparent (the default), all occurrences of the color in the image will be made transparent.

If an image is supplied by setting an Appearance.Image property to an Imagelist index, the ImageLists TransparentColor property is looked at first. If that property is set to Color.TransparentColor, then the component's ImageTransparentColor is used. If it is set to Color.TransparentColor, then no color masking is done.

If an image is supplied by setting the Appearance.Image property to an image, the component's ImageTransparentColor is used. If it is set to Color.TransparentColor, then no color masking is done.

 Returns or sets whether only the of the MdiTabGroup containing the is displayed.

Note: As the MdiTabGroup that contains the changes (because either the ActiveTab is moved to a different group or because a different MdiTab/Form is activated) the MdiTabGroup that is displayed will automatically change.

 Returns or sets how the non-maximized MdiTabGroups are displayed when the is set to true. Returns or sets whether the end user can change the .

This property defaults to false. When set to true, the tab context menu that is displayed when you right click on a tab will include an additional option - Maximize. This menu item is used to toggle the property.

 Gets/sets the default appearance for the component.

The Appearance property is the default appearance for all the elements used by the . It is used when resolving the appearance of the tabs, tab area, splitter bar, tab list button, close button and scroll buttons. If you want to control those items individually, you may use the specific appearance properties for those items. For example, to affect only the splitter bar you can use the .

 Indicates whether an object has been created. Returns true when the Appearance object for the property has been created.

Use this property to determine if an object has been created. Appearance objects in general are not created until the properties associated with them are accessed.

 Gets/sets the appearance for the splitter bars.

All items in the collection except the last item have a splitter bar that may be used to adjust the at runtime as long as the is at least 0. The SplitterAppearance determines the colors used to display the splitter bar.

 Indicates whether an object has been created. Returns true when the Appearance object for the property has been created.

Use this property to determine if an object has been created. Appearance objects in general are not created until the properties associated with them are accessed.

 Returns or sets the whose mdi child forms are managed by the UltraTabbedMdiManager.

The MdiParent is the whose will be managed by the UltraTabbedMdiManager. As mdi child forms are created, objects are created for each form. The MdiTab for a specific Form may be obtained using the method.

Note: Setting the property to null (Nothing in VB) will unhook the UltraTabbedMdiManager from the Form and release all objects and . To temporarily disable the mdi interface, use the property.

 Returns a set of cached objects.

The HiddenTabs is a collection of objects representing objects that are not yet visible. When the associated form is made visible, the associated MdiTab is removed from the HiddenTabs and moved into the collection of an and the event is invoked. When the form is hidden, the associated MdiTab is removed from its containing and added to the HiddenTabs collection.

 Indicates if the collection contains any items Indicates if a new can be created. Returns true if the current number of is less than the Indicates if an is being dragged Returns true if an is currently being dragged Returns or sets the borderstyle of the mdi client area when the UltraTabbedMdiManager is enabled.

The BorderStyle property is used to modify the border style of the mdi client area when the property is set to true. By default the mdi client in .Net displays a three dimensional sunken border. To allow the mdi client to more closely resemble the appearance of Visual Studio .Net, the BorderStyle defaults to Solid.

Note: Since there is no mechanism available on the mdi client to modify its border, this is done using unmanaged code and therefore will require that the assembly have unmanaged code rights in order to be able to adjust the border style of the mdi client.

 Returns or sets the color used for the mdi client area border.

The BorderColor property determines the color of the border of the mdi client area when the property is set to true. When the is set to a three dimensional style border the BorderColor is used as the base color.

Note: Since there is no mechanism available on the mdi client to modify its border, this is done using unmanaged code and therefore will require that the assembly have unmanaged code rights in order to be able to adjust the border style and border color of the mdi client.

 Gets/sets the view style for the control. Returns the resolved Gets or sets the format in which the user customizations settings will be saved and loaded Gets/sets the setting that controls which tab is activated when navigating using the keyboard. Returns the event handler that for the method that is used to receive notifications when a property on a sub-object has changed. Gets the UltraToolbarsManagerApplicationSettings instance which saves and loads user customizations from the default store Returns the property. Displays the About dialog for the control. Return the license we cached inside the constructor Gets/sets the toolbars manager. Indicates whether this component should automatically save its user configuration settings.

Note: The location where the settings are stored varies depending on the configuration of the system running the application. Information about where these locations are is currently unavailable in Microsoft's MSDN Library.

A unique string that distinguishes this UltraTabbedMdiManager form others in the solution it is being used in. This is needed to store user configuration settings.

Overriden. This property is not used by the UltraTabbedMdiManager Cancelable event that occurs when a will be displayed for an

The InitializeContextMenu is invoked when the end user right clicks on an and when a tab is released within the mdi client area in an area that would not result in a new tab group or tab move. The indicates the reason that the context menu is being displayed. The Cancel parameter can be set to true to prevent the context menu from being displayed.

 Event that occurs when a new is created for an mdichild form.

The InitializeTab event is invoked when a new is created for an mdi child form before it has been associated with an . This event provides an opportunity to initialize the tab before it is displayed.

Note: Invoking one of the move methods (e.g. ) on the will result in an exception.

 Event that occurs when a new is created.

The InitializeTabGroup event is invoked when an is created and provides an opportunity to initialize its settings before it is displayed.

Note: Attempting to move a tab into the during the event will generate an exception.

 Event that occurs when an is deserialized so that it may be associated with a

The RestoreTab event is invoked when the or method is called and there are serialized objects. The event is invoked so that the deserialized tab can be associated with an mdi child form. This is done by setting the property. If this is not specified, the MdiTab will be discarded. You can use the property of the MdiTab to store information about the form it should be associated with during deserialization (e.g. store a file name).

Note: Any forms created during this event will not have an associated with it so that a form can be created in this event and used to set the property.

 Cancelable event that occurs before an is closed.

The TabClosing event is invoked when method is invoked, the close button is pressed or the "Close" menu option in the tab's context menu is selected. If the event is cancelled, no action is taken. Otherwise, the action specified in the is taken and the event is invoked.

 Event that occurs after an is closed.

The TabClosed event is invoked when method is invoked, the close button is pressed or the "Close" menu option in the tab's context menu is selected after the action specified in the is taken.

 Cancelable event that occurs when an is about to be dragged.

The TabDragging event is invoked before a drag operation for a tab begins. If the event is cancelled, the drag operation will be cancelled. Otherwise, the drag will commence and the event as the tab is dragged. When the drag operation completes successfully (i.e. it is not cancelled using the escape key), the event will be invoked.

Note: This event will not be invoked if the resolved for the tab is set to None since that tab is not considered draggable.

 Event that occurs after an drag operation is completed.

The TabDropped event is invoked when a drag operation has completed. The event will be invoked after any related move operations have occurred.

 Event that occurs during the drag of an to determine if the specified location is a valid drop point.

The TabDragOver event is invoked during a drag operation when the mouse is positioned over a valid drop location. The can be set to true to indicate to the end user that this location is not a valid drop point. Also, the cursor displayed may be initialized using the . The indicates the action that will be taken if the tab is released at this .

 Cancelable event that occurs before an is resized.

The TabGroupResizing is invoked when one or more objects are about to have their modified. This could be as a result of a splitter drag (), resizing the mdi client, creating a new MdiTabGroup, removing an existing MdiTabGroup or explicitly setting the or .

The sum of the extents must always equal the extent of the client area of the mdi client. Whether they must equal the width or height is dependant upon the . If the event is cancelled, the sum of the extents is calculated. If the sum does not equal the extent of the mdi client area, the extents are adjusted.

Note: Setting the will implicitly cancel the event and the tab groups extents will be verified as described above.

 Event that occurs after an is resized.

The TabGroupResized is invoked after the of one or more objects have been modified. This could be as a result of a splitter drag (), resizing the mdi client, creating a new MdiTabGroup, removing an existing MdiTabGroup or explicitly setting the or .

 Cancelable event that occurs before an is scrolled.

The TabGroupScrolling is invoked when the tabs in an are about to scroll. This could be the result of clicking on a the , invoking the method, etc. The may be set to true to prevent the scroll operation.

 Event that occurs after an is scrolled.

The TabGroupScrolled is invoked after the tabs in an have been scrolled. This could be the result of clicking on a the , invoking the method, etc.

 Cancelable event that occurs before an is selected.

The TabSelecting is invoked when the is about to change. Selecting an will activate the with which it is associated.

Since the ActiveTab represents the active mdi tab and mdi child form activation is maintained by their zorder, the ActiveTab must be the of its . Since the ActiveTab must be selected, as the ActiveTab changes, the TabSelecting event will be invoked.

Note: The TabSelecting event may not always be cancellable since the activation/selection may occur as a result of an external action - e.g. when the mdi child is first created.

 Event that occurs after an has been selected.

The TabSelected is invoked after a tab has been selected.

 Event that occurs when the visibility of the of an is changed to true and the MdiTab is being displayed in an .

objects associated with non-visible forms are stored in the collection and are not associated with a particular . When the associated is made visible, the tab is removed from the HiddenTabs and added to a MdiTabGroup. The TabDisplaying event is invoked when the tab has been added to a MdiTabGroup but before the display has been updated.

 Event that occurs after the visibility of the of an is changed to true and the MdiTab is displayed in an .

objects associated with non-visible forms are stored in the collection and are not associated with a particular . When the associated is made visible, the tab is removed from the HiddenTabs and added to a MdiTabGroup. The TabDisplayed event is invoked after the tab has been added to a MdiTabGroup.

 Event that occurs when an is about to be repositioned.

The TabMoving event is invoked before an is moved from one position to another. This may be a reposition in the of the containing or as a result of being moved to a different . The end user may reposition a tab by either dragging the tab or via the right click context menu. Where the user may reposition the tabs is dependant on many settings including the tab's , the of the tab groups, as well as the , and . Programatically, the tab may be repositioned to a specific MdiTabGroup using the or to a new MdiTabGroup using the method. A tab may also be repositioned using its method or it may be repositioned by its containing group using the .

 Event that occurs after an has been repositioned.

The TabMoved event is invoked after an is moved from one position to another. This may be a reposition in the of the containing or as a result of being moved to a different . The end user may reposition a tab by either dragging the tab or via the right click context menu. Where the user may reposition the tabs is dependant on many settings including the tab's , the of the tab groups, as well as the , and . Programatically, the tab may be repositioned to a specific MdiTabGroup using the or to a new MdiTabGroup using the method. A tab may also be repositioned using its method or it may be repositioned by its containing group using the .

 Event that occurs when the splitter bar for an is about to be repositioned.

All objects in the collection have a splitter bar except the last one. The splitter bar is used by the end user to modify the of a tab group. When the user presses the logical left mouse button on the splitter bar, the event is invoked to determine whether to allow the splitter bar to be repositioned. If the event is not cancelled, the user may move the splitter bar. Once the splitter bar is released, the is updated (as well as that of the adjacent tab group) and the event is invoked.

When the user presses the logical left mouse button on the splitter bar, the event is invoked to determine whether to allow the splitter bar to be repositioned. If the event is not cancelled, the user may move the splitter bar. Once the splitter bar is released, the is updated (as well as that of the adjacent tab group) and the event is invoked.

 Event that occurs when the or method is invoked so that each tab's may be initialized.

The StoreTab event is invoked for each when the or method is called. The purpose of the event is to provide a place to initialize the property before serializing the tabs. The PersistedInfo property can be set outside of this event but often the criteria you will need to create the appropriate form during deserialization will change during the life of the application. This event provides a centralized point to initialize the tabs immediately before serialization without having to iterate through the of all the and the .

 Event that occurs after the has changed.

The TabActivated event is invoked when when an is activated.
