    What could be causing this error?

    Sys.InvalidOperationException: Type Telerik.Web.UI.RadComboBoxEventArgs has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.

    You can see the error in Firebug  here

    Fixed.. I found the problem..

    Thinking it was needed when I implemented a RadComboBox on my page I added this.

    <script src="../Scripts/RadComboBoxScripts.js" type="text/javascript"></script>

    Problem be gone.
