title: Can't get UpdatePanel to refresh on GridView paging
body: <p>I have a GridView in an UpdatePanel (ASP.Net 2.0) . </p>
  
  <p>I have this code for the PageIndexChanging method of the grid view:</p>
  
  <pre><code>   protected void grdProductSearch_PageIndexChanging(object sender, GridViewPageEventArgs e)
     {
              grdProductSearch.PageIndex = e.NewPageIndex;
              grdProductSearch.DataBind();
     }
  </code></pre>
  
  <p>For the UpdatePanel, in the Triggers collection I have added the GridView and the PageIndexChanging method for the EventName.</p>
  
  <p>Yet, the grid displays data correctly but there is no response when I click the page numbers at the bottom. What am I doing wrong? </p>
  
  <p>Thanks.</p>
