            System.IO.StringWriter sw = new System.IO.StringWriter();

            {

                //Get the HTML for the control.
                dgGrid.RenderControl(hw);
                //Write the HTML back to the browser. 
                Response.ContentType = "application/vnd.ms-excel";
                Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");
                this.EnableViewState = false;
                Response.Write(tw.ToString());
                Response.End();
