ASP.NET 生成报表的几中方案？

• 1. 用html 表格绘制报表，javascript导出EXCEL
• 2. 采用datagrid绑定报表数据，用后台方法导出

            //Response.AppendHeader("Content-Disposition", "attachment;filename=dayReport" + flag + ".xls");
            //Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
            Response.Clear();     
            Response.Buffer = true;
            //Response.Buffer = true;
            Response.AppendHeader("content-Disposition", "attachment;filename=" + DateTime.Now.ToString("yyyy-mm-dd") + ".xls");
            //Response.AppendHeader("Content-Disposition","attachment;filename="+DateTime.
            //Now.ToString("yyyyMMdd")+".xls");           
            Response.ContentEncoding = System.Text.Encoding.UTF8;   
            Response.ContentType = "application/ms-excel";   
            this.EnableViewState = false;

• 3. 采用Grid++Report提供的插件进行B/S报表的开发
• 4.采用asp.net内置的报表工具，Report向导。
