Roll Your Own Postback Event

I found out how to cause javascript to trigger a server side event by trying to make something happen with the Telerik control suite (http://www.telerik.com/). This might be of interest to some of you, and I believe if your updated control is wrapped in an ajax update panel a full post back may not even take place (at least with Telerik's controls the below technique seemed to work as an ajax enabled partial post back.

Experiment for yourself.


Javascript

<script type="text/javascript">
    function myfunction(param)
    {
      __doPostBack("<%= myControl.ClientID %>", "myargs");
    }
  </script>

And in your in your page code...

   protected override void RaisePostBackEvent ( IPostBackEventHandler source, string eventArgument )
    {
      base.RaisePostBackEvent ( source, eventArgument );
      if ( source == this.myControl && eventArgument.IndexOf ( "myargs" ) != -1 )
      {
        // Do whatever here
      }
    }
