I have a UserControl that contains a RadSplitter with two RadPanes. The UserControl is added to a RadPageView and RadMultipage dynamically when a user selects a menu option. So far so good, however, when a user resizes the client browswer window only the UserControl in view is resized accordingly while the UserControl in a non-visible RadPageView is not. How can I force the RadPageView to resize when out of view?
