  I'm using the ComboBox control, and I can't figure out how to get a reference to it in javascript. It functions correctly, just can't get a reference to it, client-side.
  
  I declare it like this:
  
  

  @(Html.Telerik().ComboBox()

                    .Name("SourceSiteSelector")

                      .AutoFill(true)

                      .DataBinding(binding => binding.Ajax().Select("_AjaxSourceSiteLoading", "Common"))

                      .Filterable(filtering => { filtering.FilterMode(AutoCompleteFilterMode.Contains); })

                          .ClientEvents(events => events.OnChange("SourceSiteSelector_onChange"))

                      .HighlightFirstMatch(true)

                      .HtmlAttributes(new { style = "width: 400px;" })

                  )

  
  But when I try to get a reference to it using the technique from the help files, this alert returns a value of true. It always returns null:
  

  <script type="text/javascript">

      function SourceSiteSelector_onChange() {

          var combo = $('#SourceSiteSelector').data('tSourceSiteSelector');

          alert(combo == null);

      }

    

  </script>

  
  What am I missing?
  
  
  Thanks!

  Hello Andy,
  
  The client-side objects for the Telerik Extensions can be obtained from the jQuery data by using a name in the format "t" + "ExtensionName". For example, to get the object for the ComboBox in your case, you should use the code in the snippet below:
  

  var combo = $('#SourceSiteSelector').data('tComboBox');
