DockAllow event
If you don’t want to make two docked controls tabbed together, then you can cancel the tabbed docking in DockAllow event as follows.
C#
void dockingManager1_DockAllow(object sender, DockAllowEventArgs arg) { if (arg.DockStyle == Syncfusion.Windows.Forms.Tools.DockingStyle.Tabbed) arg.Cancel = true; }
VB
Private Sub dockingManager1_DockAllow(ByVal sender As Object, ByVal arg As DockAllowEventArgs) If arg.DockStyle = Syncfusion.Windows.Forms.Tools.DockingStyle.Tabbed Then arg.Cancel = True End If End Sub
