GridView中导出数据到EXCEL

在GridView中导出数据到EXCEL 
只要在页面中添加一个按钮Button1，给按钮加上以下代码即可解决。
protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Clear();
        Response.Buffer = true;
        Response.Charset = "GB2312";
        Response.AppendHeader("Content-Disposition", "attachment;filename=FileName.xls");
        // 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.GridView1.RenderControl(oHtmlTextWriter);
        Response.Output.Write(oStringWriter.ToString());
        Response.Flush();
        Response.End();

    }

如果有提示 类型“GridView”的控件 必须放在具有 runat=server 的窗体标记内。相关的错误就重写下面一个方法便可。

 public override void VerifyRenderingInServerForm(Control control)
        {
            //   base.VerifyRenderingInServerForm(control);
          
        }
