请问GridView_BindByDate()出错如何解决？

Question

我是用一个GridView的控件绑定SqlDataSource读出来的数据的，然后用http://blog.csdn.net/lz00728/article/details/7204818这里说的方法导出带分页数据的GridView到Excel，可是，还没运行就语法错误了...是不是我不能用这个函数？如果绑定的是一个SqlDataSource如何做到“为GridView重新绑定数据源 ”？就是说这句怎么改才适合我这种绑定的代码？

找到一个代码，用了下，发现没有网格线，而且设定了写字符串用户名神马前面的“0”还是没了上代码        protected void ButtonExcel_Click(object sender, EventArgs e)
        {
            Export("全校教师工作量汇总表.xls", this.GridView1);
        }        public static void Export(string fileName, GridView gv)
        {
            HttpContext.Current.Response.Clear();
            HttpContext.Current.Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", fileName));
            HttpContext.Current.Response.ContentType = "application/ms-excel";
            HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");            using (StringWriter sw = new StringWriter())

                    Table table = new Table();
                    string style = @"<style> .text { mso-number-format:\@; } </script> ";                     if (gv.HeaderRow != null)
