Syntax
'Declaration
 
Public Overloads Function MoveToGroup( _
   ByVal group As MdiTabGroup _
) As Boolean
public bool MoveToGroup( 
   MdiTabGroup group
)

Parameters

group
TabGroup to contain the tab

Return Value

Returns True if the tab was repositioned. Otherwise False is returned.
Example
The following example demonstrates some of the ways for repositioning MdiTab objects.
