if ((!(dhc.ParentController == null) && (dhc.ParentController.GetType() == DockTabController)))
{
    DockTabController dtc = ((DockTabController)(dhc.ParentController));
    tabcontrol = ((DockTabControl)(dtc.TabControl));

Dim tabcontrol As TabControlAdv = New TabControlAdv
Dim dhost As DockHost = CType(Me.treeViewUserControl1.Parent, DockHost)
Dim dhc As DockHostController = CType(dhost.InternalController, DockHostController)
If ((Not (dhc.ParentController) Is Nothing) _
