AllowClose Property (MdiTabSettings)

Returns or sets whether the MdiTab may be closed.
Syntax
'Declaration
 
Public Property AllowClose As Infragistics.Win.DefaultableBoolean
public Infragistics.Win.DefaultableBoolean AllowClose {get; set;}
Remarks

An MdiTab can be closed 2 ways using the user interface of the UltraTabbedMdiManager. One way is using the close button (appears as an "X" in the MdiTabGroup) and the other is via the context menu displayed when right clicking on a tab. The close button displayed in the MdiTabGroup may be hidden by setting the MdiTabGroupSettings.ShowCloseButton to false but the option in the context menu will still be available. If the AllowClose resolves to false (true is the default value) the option in the context menu will not be displayed and the close button (if displayed) will be disabled when the tab is the selected tab. Regardless of the AllowClose setting, the tab may be closed using the MdiTab.Close method.

Example
The following examples demonstrates how to set various MdiTabSettings and MdiTabGroupSettings properties which will serve as the default values for the MdiTabGroups and MdiTab objects managed by the UltraTabbedMdiManager component.
