如题，我用的时数据直接导出到Excel ，
DadaGrid的内容是绑定DataSet 的
下面 的代码好像只是把xls文件写到了服务器上，我要写在客户端浏览器上？当数据量大的时候就丢失数据
Response.Clear();
Response.Buffer= true;
Response.Charset="宋体";
string FileName ="type"+DateTime.Now.ToString("yyyyMMdd") + DateTime.Now.Hour + DateTime.Now.Minute + DateTime.Now.Second + ".xls";
Response.AppendHeader("Content-Disposition","attachment;filename="+FileName+"");
Response.ContentEncoding = System.Text.Encoding.UTF8;//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。
this.EnableViewState = false;
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);
this.DataGrid1.RenderControl(oHtmlTextWriter);
Response.Write(oStringWriter.ToString());
Response.End();
