title: AJAX CascadingDropdown - Setting the selected index
body: <p>I have a CascadingDropDown on an ASP.NET page.</p>
  
  <p>Now, the prompt text is "Select State". (list of states).</p>
  
  <p>However, on a different version of this page (ie querystring), i might want to set the selected index to "California" for example.</p>
  
  <p>How can i do this?</p>
  
  <p>The web service used by the ajax control (ie GetStates) gets invoked at the same time the jquery document.ready function is triggered (ie asynchronously).</p>
  
  <p>So when i try and set the selected index in jquery, the items are not yet bound.</p>
  
  <p>Is there a way to attach a handler to the ajax dropdown so that i can set the selected index once the webservice call has completed, and the items are bound?</p>
