title: Add a click event to a listbox filled with objects in code
body: <p>I'm trying to sho a contextmenu on right-click on an item in a listbox. So i'm binding a list of "Users" to my listbox. Then i'm a bit lost. I thought i could foreach the list and add a mouserightdown event on the listboxitems, but i can't figure out how.</p>
  
  <p>Is this a good way, or does anyone know a better way of accomplishing what i want.</p>
  
  <p>Thanks in advance.</p>
