title: AdvancedDataGrid Multi-column programmatic sorting
body: <p>I need to to a programmatic multi column sorting on the AdvancedDataGrid.
  The issue is, currently I am implementing paging on my grid. So, if I sort the data, only the perticular page is being sorted. So, I need to sort the entire list by the column criteria.</p>
  
  <p>I tried HeaderRelease event, but I guess it is of no use as I need to make a round trip call to the server to get the sorted data. Is there any way I can implement that. I also need to show the sort markers in the Column headers' right position, indicating the sort numbers and direction.</p>
  
  <p>'ll really appreciate the help</p>
  
  <p>Thanks :)</p>
