[QUOTE="osre, post: 1124690, member: 150866"] Is the menu on an other Screen, or is it a child control, that is defined in an different XAML file? If it is a child control, you could add an Event Trigger for ItemsControl.SelectionChanged Event in the outer Container. In any case I try to get the implementation in the model done before the Weekend. One more question: You said you want to have this text as a caption of the current Screen. Does this mean you Need to set the text of the Group menu item when it's selected, but the text of the actual menu item only when it gets activated (clicked)? This would be my guess. This would mean that for the actual menu items it is not the selection changed Event or IsSelected property to react. The down side I see here, if a Screen is not opened by the menu item, but by a Keyboard shortcut, the heading would not be set, since the menu item was never selected/activated. So it would be better to bind the caption to the active subscreen. No idea if this makes sens. Just an idea. [/QUOTE]
