The radpanegroup has an option, OverflowMode, which derives from the tabcontrol. This property, when set, does nothing. I would expect that it would behave as the tabcontrol does. When a radpanegroup has too many radpanes, the radpanes just start getting smaller and smaller. Is there a workaround for this? We really need the ability to have the tabs wrap to a new line. I looked at the template for the documenthost and tried to replace the ItemPresenterElement with a WrapPanel but it did not work. Any suggestions?
