body: <p>i have a listbox with a datatemplate that looks like this:</p>
  
  <pre><code>spackpanel
      textbox1
      textbox2
  /stackpanel
  </code></pre>
  
  <p>how i want to add a context menu, so i modified it like:</p>
  
  <pre><code>spackpanel
      contextMenu
          contextMenuItem
      /contextMenu
      textbox1
