title: asp.net ajax postback: how to remain scroll position of a panel
body: <p>I have a panel, inside a panel there are some checkbox and radiobuttonlist. This panel is place inside an UpdatePanel ajax.</p>
  
  <p>When I click on a checkbox, it will raise autopostback with ajax supported, then the scrollbar of the panel always move back to the first position. It does not keep the current scrolling position.</p>

  <pre><code>this.Page.SetFocus("PanelTrips");
  this.MaintainScrollPositionOnPostBack = true;
  </code></pre>

  <p>Thanks in advance.</p>
