I think it will help you

string filename = String.Format("Results_{0}_{1}.xls", DateTime.Today.Month.ToString(), DateTime.Today.Year.ToString());
        if (!string.IsNullOrEmpty(GRIDVIEWNAME.Page.Title))
            filename = GRIDVIEWNAME.Page.Title + ".xls";

        HttpContext.Current.Response.Clear();

        HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=" + filename);


        HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
        HttpContext.Current.Response.Charset = "";

        System.IO.StringWriter stringWriter = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter);



        System.Web.UI.HtmlControls.HtmlForm form = new System.Web.UI.HtmlControls.HtmlForm();
        GRIDVIEWNAME.Parent.Controls.Add(form);
        form.Controls.Add(GRIDVIEWNAME);
        form.RenderControl(htmlWriter);

        HttpContext.Current.Response.Write("");
        HttpContext.Current.Response.Write(stringWriter.ToString());
        HttpContext.Current.Response.End();
