Is there any way to find out mouse left button up event outside of an element in wpf?

I will define an event for m开发者_开发问答y border element that relize mouse left button up outside of this element.

You can get mouse up event outside the element who received mouse down, if on the mouse down you call element.CaptureMouse() (and on mouse up, do not forget to call element.ReleaseMouseCapture()).

        Mouse.Capture (this,CaptureMode.SubTree);
        AddHandler ();

    private void AddHandler()
    {
        AddHandler (Mouse.PreviewMouseDownOutsideCapturedElementEvent,new MouseButtonEventHandler (HandleClickOutsideOfControl),true);
    }
