title: WPF and routed event
body: <p>I have a WPF window, which has a button that is inside a stackPanel, which is inside another stackPanel</p>
  
  <p>I wrote an event handler for the button for the MouseDown event.
  I want to execute this eventHandler three times for the button and the parent (stack panel) and the parent's parent</p>
  
  <p>How can I achieve that with the routed event, by writing only one event handler?
  I don't want to repeat the event handler code.</p>
  
  <p>Thanks</p>
