title: add item to dropdownlist
body: <p>I'm trying to add an item to a DropDownList from an Oracle datareader, but I keep getting an error that states the line has some invalid arguments.</p>
  
  <p>Can I simply specify the text and the value? In which case, I want them to be the same value coming from the datareader.</p>
  
  <pre><code>TRef.Items.Add(new ListItem(dr["t_ref"], dr["t_ref"]));
  </code></pre>
