      I think runat=server has to be added in form control not in gridview.

                      In order to overcome the error, We have to override the below function. public override void VerifyRenderingInServerForm(Control control) { }

                      Regards, Jay :)

                        You cannot render the GridView Control into HTML directly. Use DataGrid. May be Jay_se is correct. But I haven't tried that before. We also had this issue before and we solve that using DataGrid. We can used JavaScript get the HTML String of the GridView and do the same.
