I create a dynamic form and dock it to DockableControlPane, then I set IsMdiChild property to true. This will allow my form to be displayed onTabbedMDIManager as a tab. Now I can make my tab floating or dockable by right clicking on this tab and choosing appropriate menu. But the problem is once it is floating or docked then I am unable to toggle its dock state even after double clicking on the tab. I mean If it is made floating then double clicking on floating window should bring this window back to docked state (I am ok if it does not go to MDIChild stae). Similarly if the window is dockable and I double click on caption does not make it floating.
