    public void ToExcel(System.Web.UI.Control control, string filename)

        //下面这行很重要， attachment 参数表示作为附件下载，您可以改成 online在线打开
        //filename=FileFlow.xls 指定输出文件的名称，注意其扩展名和指定文件类型相符，可以为：.doc 　　 .xls 　　 .txt 　　.htm
        System.Web.HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + filename + ".xls");
        System.Web.HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
        //Response.ContentType指定文件类型 可以为application/ms-excel、application/ms-word、application/ms-txt、application/ms-html 或其他浏览器可直接支持文档
        System.Web.HttpContext.Current.Response.ContentType = "application/ms-excel";

        System.IO.StringWriter tw = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter hw = new HtmlTextWriter(tw);

        control.Page.EnableViewState = false;
        control.RenderControl(hw);

        System.Web.HttpContext.Current.Response.Write(tw);
        System.Web.HttpContext.Current.Response.End();
    }

 

 

 

 

当出现"类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内。"错误时.在导出页面重载VerifyRenderingInServerForm方法。

 

public override void VerifyRenderingInServerForm(System.Web.UI.Control control)
{

}
