title: ListBox and Datasource - prevent first item from being selected
body: <p>Hey. I've got the following code that populates my list box</p>
  
  <pre><code>UsersListBox.DataSource = GrpList;
  </code></pre>
  
  <p>However, after the box is populated, the first item in the list is selected by default and the "selected index changed" event fires. How do I prevent the item from being selected right after the list box was populated, or how do I prevent the event from firing?</p>
  
  <p>Thanks</p>
