    Add a new event handler for the Unloaded event of RadDocking

        EventManager.RegisterClassHandler(typeof(RadDocking), RadDocking.   UnloadedEvent, new RoutedEventHandler(OnUnloaded)); 
        EventManager.RegisterClassHandler(GetType(RadDocking), RadDocking.  UnloadedEvent, New RoutedEventHandler(OnUnloaded)) 
  2. Implement the save logic in the newly added event handler for the Unloaded event.

        private void OnUnloaded(object sender, RoutedEventArgs e) 
            using (IsolatedStorageFile storage = IsolatedStorageFile.   GetUserStoreForAssembly()) 
                using (var isoStream = storage.OpenFile("RadDocking_Layout.xml",    FileMode.Create)) 
        Private Sub OnUnloaded(ByVal sender As Object, ByVal e As RoutedEventArgs) 
            Using storage As IsolatedStorageFile = IsolatedStorageFile. GetUserStoreForAssembly() 
                Using isoStream = storage.OpenFile("RadDocking_Layout.xml",     FileMode.Create) 
                End Using
