ClientUI has UXDockTray control which represents a container that hosts multiple toolbars and menu bars with support for horizontal and vertical orientation. It also features intuitive drag-drop capability allowing the hosted toolbars to be dragged and moved within itself or across UXDockTray container.

I will try to test whether the UXDockTray can be used with window control and let you know the result. (UXDockTray main function is to host one or more items that support drag and drop operation such as UXToolBar).

Reason: Update information

I have submitted this as control request to ClientUI development team under Task 1265. The team will check the feasibility to add this control in the next build of ClientUI.

I will update this thread with any news I heard from the team regarding Task 1265.
