title: How do I programmatically change ASP.NET ajax AccordionPane with javascript?
body: <p>I've got an asp.net ajax style AccordionPane control that I am trying to get/set based on some user interactions. However it seems not let me do this with javascript:</p>
  
  <pre><code>function navPanelMove() {  
    var aPane = $get('ctl00_Accordion1_AccordionExtender_ClientState');  
    openPaneID = aPane.get_SelectedIndex();  // doesn't work
  }
  </code></pre>
