Oh and to take the example further and get a client side dom reference to
the select element rendered by server side asp:DropDownList, it would be
more like this:

<script language="javascript" type="text/javascript">
  var sControlID = '<%= ddlProducts.ClientID %>';
  var dd = document.getElementById(sControlID);
  </script>

or just

<script language="javascript" type="text/javascript">
  var dd = document.getElementById('<%= ddlProducts.ClientID %>');
  </script>

Cheers,

Joe
