页面上用GridView显示数据

导出按钮Click事件

protected void Btn_DC_Click(object sender, EventArgs e)
{

        string fileName = DateTime.Now.Year.ToString() + DateTime.Now.Month.ToString() + DateTime.Now.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString();
        Response.Clear();
        Response.Buffer = true;
        Response.Charset = "GB2312"; //设置了类型为中文防止乱码的出现 EnableEventValidation ='false'
        Response.AppendHeader("Content-Disposition", "attachment;filename=" + System.Web.HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8) + ".xls"); //定义输出文件和文件名
        Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312"); //设置输出流为简体中文
        //Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。
        Response.ContentType = "application/vnd.xls";

        System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN", true);
        System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad);
        System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
        orderGdView.RenderControl(oHtmlTextWriter);
        Response.Write(oStringWriter.ToString());
        Response.End();
    }

另外还得加上

      public override void VerifyRenderingInServerForm(Control control)
    {
    }

否则程序会在这一行 orderGdView.RenderControl(oHtmlTextWriter);
报错，至于为什么会报错暂不清楚
