I have control displayed in a floating pane and I don't want it to be docked to any side and should not be converted to MDIChild. I have set the following properties on the DockableControlPane. It works by preventing it to be docked to the sides. But when the user drags the pane towards the center (of the docking interface) it can be dropped in the center which converts it to MDIChild. How can I prevent this?

pane.Settings.AllowDockBottom = DefaultableBoolean.False;
pane.Settings.AllowDockLeft = DefaultableBoolean.False;
pane.Settings.AllowDockRight = DefaultableBoolean.False;
pane.Settings.AllowDockTop = DefaultableBoolean.False;
pane.Settings.AllowDockAsTab = DefaultableBoolean.False;
pane.Settings.CanDisplayAsMdiChild = DefaultableBoolean.False;
