Sorting with serveroperation true

[Mark]

How do I allow for grid sorting by clicking on the grid headers if serveroperation is true.  I have a complex grid filtering and I need to use serveroperation(true)

Best Regards,

OK, this is now fixed I was making an error.
In my Data_Read header I had: 
 public ActionResult Data_Read(DataSourceRequest request, ...)
and I should have had
 public ActionResult Data_Read([DataSourceRequest] DataSourceRequest request

This is working,
