title: Alternating row style for GridView not working after postback
body: <p>I have an Ajax Control Toolkit Tab container, and each TabPanel contains a GridView. The GridView is initially rendered with an alternating row style. After a PostBack, the GridView in the current active tab has an alternating row style and all the other tabs that weren't visible contain GridViews with no alternating row style.</p>
  
  <p>How do I get the style to apply to the other GridViews even if they are in a tab that is not visible?</p>
