ASP.Net Controls always render back into plain HTML Controls. When using javascript you can call the item exactly as you normaly would a dropdown. The dropdown list will have the ID of your RadComboBox.

var myDropDown = document.getElementById('ExampleDropDownList');

and you will have access to your dropdown list.
