radTabControl.SelectedItem = radTabItem; // set tab as the active one
radTabItem.Content = userControl;
The code above runs but the contents of the previous RadTabItem remain on srceen.
The tab and visual indicator showing what tab the user is on show but all the contents are those that belong to the previous tab.
Is there a refresh command that I'm missing?
i.e. setting SelectedItem does not have the same result as clicking the tab.
