title: How do I clear a combobox?
body: <p>I have some combo-boxes that are set up as drop down lists, and the user can pick a number in them. I also have a Clear button that should clear the text from the combo boxes but I can't seem to get it. I've tried:</p>
  
  <pre><code> //doesn't work
   cboxHour.Text = "";
  </code></pre>
  
  <p>and</p>
  
  <pre><code>//doesn't work
  cboxHour.ResetText();
  </code></pre>
  
  <p>This seems like it should be so straight forward but I'm just not getting it. </p>
