I have to export data from listview to excel, I am using below code, it exports data to excel but along with html design, how could I export listview data without exporting HTML content...

Response.ClearContent();
            Response.AddHeader("content-disposition", "attachment;filename=Result.xls");
            Response.ContentType = "applicatio/excel";
            StringWriter sw = new StringWriter(); ;
            HtmlTextWriter htm = new HtmlTextWriter(sw);
            ListView2.RenderControl(htm);
            Response.Write(sw.ToString());
            Response.End();
