I have the following scenario. Dock inteface consists of many RadPanes. Each RadPane can be a part of some RadPaneGroup. Then for each RadPane I want to know if it is visible to user. Not to confuse with IsHidden property. E.g.: in my case, RadPane is invisible when it is not SelectedItem in RadPaneGroup (though IsHidden is false).
Is there any way to track visibility state of RadPane?
