title: Gridview sorting and updatepanel
body: <p>I am trying to use an update panel together with a gridview, but I am having some difficulties sorting the gridview. I tried to follow @dfowler in this <a href="https://stackoverflow.com/questions/213148/sort-columns-of-gridview-in-asp-net-c">thread</a> </p>
  
  <p>But when I try to sort I get this error when trying to databind the sorted list:
  "The data source does not support server-side data paging."</p>
  
  <p>Anyone having some clue what I do wrong?</p>
