title: Telerik Radgrid GridDataItem.DataItem is empty when updating (OnUpdateCommand handler)
body: <p>When handling the OnUpdateCommand event on a RadGrid the DataItem is null.</p>
  
  <p>I thought that this would also represent the data item being represented by the row.</p>
  
  <p>The Radgrid is populated from an IList and in the handler the code looks like this...</p>
  
  <pre><code>protected void rgAllocatedClients_UpdateCommand(object sender, GridCommandEventArgs e)
  {
      if (e.Item is GridDataItem)
      {
          var gridDataItem = e.Item as GridDataItem;
          var client= gridDataItem .DataItem as Client;
          ....
          ....
  </code></pre>
  
  <p>This works find when handling the ItemDataBound event but not when handling the UpdateCommand event. I really need this as in my Client class is the Id of the row I want to handle the update for.</p>
  
  <p>Thanks,</p>
