Requirements:

- Multiple screen RDP-Session with option "Show windowcontents while dragging" turned off.

- RadTabbedwindow with AllowTransparency = false (might not be necessary)

 

When dragging a maximized TabbedWindow to a different screen into maximized mode, it is allways maximized on the primary screen.
Dragging it on the target screen so that it is not maximized and then clicking maximize works.

The issue only appears when the mentiond setting in the RDP-Session is turned off.

when use the RadTransitionControl's SlideAndZoomTransition effect for the RadTabControl, the radComboBox Multiple Selection will lost in the  tabItem。

the  radComboBox data is from the mvvm binding,after change the tabitem,the Multiple Selection become single selection.

the RadTabControl's style is following:

           ...

           <ControlTemplate x:Key="TabControlTemplate" TargetType="telerik:RadTabControl">
