DhtmlxGrid | Callback on Sorting

H,

I am sorting columns in DhtmlxGrid . There is one requirement in which I have to pass some parameter to the next page that defines on which column sorting has been applied . Does dhtmlxgrid provides any callback whenever sorting is applied on the grid.

Thanks

You can use "onBeforeSorting" event (available in PRO version only). This event occurs before starting data sorting. onBeforeSorting event passes the following parameters: 
column index
sorting type (“str”,”int”,”date”)
direction of sorting (“asc”,”des”)

Event is blockable (if custom code, attached to event, returns value different from true - sorting operation will be blocked) 
  grid.attachEvent("onBeforeSorting", function(ind,type,direction){
  //any custom logic here
  return false;
  });
