title: Is it possible to trigger AJAX CollapsiblePanelExtender animation from code behind?
body: <p>I am using an AJAX CollapsiblePanelExtender for several sections of a form. I can collapse a panel programatically using the following 2 lines:</p>
  
  <pre><code>        ajaxCollapsiblePanelExtender1.Collapsed = true;
          ajaxCollapsiblePanelExtender1.ClientState = "true";
  </code></pre>
  
  <p>However, the expand/collapse animation does not play as when the Expand/CollapseControlID is clicked. It simply appears in the collapsed state. Is it possible to trigger this animation programatically?</p>
