I have found the solution ,

you need to register this code within the CallingDataMethod GridView event :

 protected void GridView1_CallingDataMethods(object sender, System.Web.UI.WebControls.CallingDataMethodsEventArgs e)
        {
e.DataMethodsObject = this;
        }

and every thing will work fine

thanks
