I have a WPF application running inside Internet Explorer. One of the dialogs attempts to open a RadWindow when the user presses a button. However, the user will never see the RadWindow. I see the same problem with the RadScheduleView, which does not show the edit appointment dialog in a WPF application inside IE, so I'm guessing that it uses RadWindow for this dialog.
When I call MyRadWindow.Show() it seems to create the instance, but the Owner property is null. Also, the following call does not detect any windows:
Just a note, the Silverlight version of RadWindow works fine in a Silverlight application running in Internet Explorer.
