title: How to prevent flickering during postback on IE9
body: <p>I have couple of dropdownlist controls in my page which have onselectedindexchanged events. When I change my selection, a postback will occur, which will cause flickering on IE9, not on firefox. I found a way to stop the flickering on IE by using:</p>
  
  <p>meta http-equiv="Page-Enter" content="Alpha(opacity=100)"</p>
  
  <p>But it didn't work on IE9. Can anybody suggest a way to stop the flickering on IE9 during postback?</p>
