  <p>Let's consider this small piece of code:</p>
  
  <pre><code>listbox.DataSource = base_items;
  listbox.DisplayMember = "Name";
  // ... a bit later in the program
  base_items.Add(  new Base_Item("Unnamed")  );
  </code></pre>
  
  <p>From this point, how do I do to make the listbox update its items? The only way for me to see the update is to close the window and reload it again. </p>
