title: Server Side Sort JQGrid Sort Button Not Working
body: <p>I have declared this in my jqgrid with 'json' data:</p>
  
  <pre><code>sortname: 'CascadeId',
  sortorder: 'asc',
  sortable: true,
  </code></pre>
  
  <p>But Sorting button has  no effect. I have implemented server side sorting with asp. but button is not working. Can you indicate how to enable the button?</p>
