模态框上导出Gridview问题

Question

各位，在弹出的模态框上，将GridView里的内容导出到Excel。怎么不好用呀！我的导出的后台代码public static void ToExcel(GridView gvExport, string fileName)
        {
            HttpContext curContext = HttpContext.Current;
            StringWriter strWriter = null;
            HtmlTextWriter htmlWriter = null;            curContext.Response.AddHeader("content-disposition", "attachment; filename=" + fileName);
            curContext.Response.ContentType = "application/vnd.ms-excel";
            curContext.Response.ContentEncoding = Encoding.UTF7;
            strWriter = new StringWriter();
            htmlWriter = new HtmlTextWriter(strWriter);            gvExport.RenderControl(htmlWriter);
            curContext.Response.Write(strWriter.ToString());
            curContext.Response.Flush();
            //curContext.ApplicationInstance.CompleteRequest();
            curContext.Response.End();        }

       public void OutExcel(int pageIndex)
        {
            Response.Clear();
            Response.Buffer = true;
            //string filename = "attachment;filename=" + System.Web.HttpUtility.UrlEncode("报表", System.Text.Encoding.UTF8) + ".xls";
            //Response.AppendHeader("Content-Disposition", filename);            string fileName = this.Date + "列表" + ".xls";
            Response.AppendHeader("Content-Disposition", "attachment;filename=" + System.Web.HttpUtility.UrlEncode(fileName));
            Response.Charset = "gb2312";
            EnableViewState = false;
            // 如果设置为 GetEncoding("GB2312");导出的文件将会出现乱码！！！
            //Response.ContentEncoding = System.Text.Encoding.UTF7;
            Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。 
            System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
            this.DataGrid1.AllowPaging = false;            this.htxtbindState.Value = "1";
            ShowData();            this.DataGrid1.RenderControl(oHtmlTextWriter);
            Response.Output.Write(oStringWriter.ToString());
            Response.Flush();
            Response.End();            this.DataGrid1.AllowPaging = true;
            this.DataGrid1.CurrentPageIndex = pageIndex;            this.htxtbindState.Value = "0";
            ShowData();
        }请参考一下 我都用这个方法导出的

   public override void VerifyRenderingInServerForm(Control control)
   {
        //base.VerifyRenderingInServerForm(control);
   }加这方法看看
