Prevent RadPane Dragging Off the Screen

[Ferenc]

Hello!

I'm using RadDocking control. Unfortunately If i drag the floating window outside the view area of the browser and drop i cannot get it back.

As i saw RadWindow control has a usefull "IsRestricted" property but there is no RadPane :(  Help me, please!

Thank You

Here's a solution to this problem that forces the Pane back into view when it's been dragged off the screen:

private ToolWindow getToolWindow(RadPane Pane)
 {
     ToolWindow toolWindow = Pane.ParentOfType<ToolWindow>();
     if (toolWindow == null)
     {
         toolWindow = (((Pane.Parent as RadPaneGroup).Parent as RadSplitContainer).Parent) as ToolWindow;
     }
     return toolWindow;
 }
 private void radDockingMain_PaneStateChange(object sender, Telerik.Windows.RadRoutedEventArgs e)
 {
     RadPane pane = e.Source as RadPane;

     if(pane != null && pane.IsFloating)
     {
         ToolWindow toolWindow = getToolWindow(pane);

         if (toolWindow != null)
         {
             toolWindow.LostMouseCapture += new System.Windows.Input.MouseEventHandler(toolWindow_LostMouseCapture);
         }
     }
 }
 void toolWindow_LostMouseCapture(object sender, System.Windows.Input.MouseEventArgs e)
 {
     ToolWindow toolWindow = (ToolWindow)sender;
     if (toolWindow.HorizontalOffset < 0)
     {
         toolWindow.HorizontalOffset = 1;
     }
     if (toolWindow.VerticalOffset < 0)
     {
         toolWindow.VerticalOffset = 1;
     }
     if (toolWindow.HorizontalOffset > radDockingMain.ActualWidth - 100)
     {
         toolWindow.HorizontalOffset = radDockingMain.ActualWidth - 100;
     }
     if (toolWindow.VerticalOffset > radDockingMain.ActualHeight - 100)
     {
         toolWindow.VerticalOffset = radDockingMain.ActualHeight - 100;
     }
 }
