TabGroups Property (MdiTabGroupResizingEventArgs)

Returns a collection of MdiTabGroup objects that are being resized.
Syntax
'Declaration
 
Public ReadOnly Property TabGroups As MdiTabGroupsCollection
public MdiTabGroupsCollection TabGroups {get;}
Remarks

Note: This collection is a flattened collection of all MdiTabGroup objects whose Extent is being changed. Therefore, the collection returned could include groups from different levels.

Example
The following sample demonstrates how to use the information passed to the TabGroupResizing event.

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.
