  Why don't you use fnDrawCallback , this callback is call at the end of fnDraw function

  I don't want to use fnDrawCallback , as I am calling fnDraw from multiple places and in this scenerio, I only want to fire callback from one position, ofcourse I can use global variable to track, but i don't want to mess code. Another option is to register and unregister the callback ( fnDrawCallback ) event, is that makes sense?

  if you don't want to use fnDrawCallback , you could instead modify the ajax query do disable the async function with fnServerData
  
  [code]
  $(document).ready( function() {
  $('#example').dataTable( {
  "bProcessing": true,
  "bServerSide": true,
  "sAjaxSource": "xhr.php",
  "fnServerData": function ( sSource, aoData, fnCallback, oSettings ) {
  oSettings.jqXHR = $.ajax( {
  "dataType": 'json',
  "type": "POST",
  "url": sSource,
  "data": aoData,
  "async": false,
  "success": fnCallback
  } );
  }
  } );
  } );
  [/code]

  Thanks for commenting. The above suggestion causes all ajax queries (table reload) to be synchronous. I just need synchronous functionality only at one place. any idea ?

  fnDraw is synchronous in all aspects other than the Ajax fetch. If you want to make it synchronous for Ajax, you need to use something like DukeAstar suggested. If you only want it to be synchronous sometimes and asynchronous at others, you need to modify the fnServerData method you use to detect which situation it is being called in and change the `async` parameter as appropriate.
