{

    Response.AddHeader("content-disposition", 

       "attachment;filename=FileName.xls");

    Response.Charset = String.Empty;

    Response.ContentType = "application/vnd.xls";

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

    System.Web.UI.HtmlTextWriter hw = new HtmlTextWriter(sw);

    GridView1.RenderControl(hw);

    Response.Write(sw.ToString());

    Response.End();

}
