[转]多个gridview怎么导出同一个Excel文档？

有三个gridview :A  B  C
B C 是根据 A查出来的 
现在想把它们都导出到一个EXCEL里面

   private void GridViewToExcel()
    {
        Response.Clear();
        Response.Buffer = true;
        Response.Charset = "GB2312";
        Response.AppendHeader("Content-Disposition", "attachment;filename=" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls");
        Response.ContentEncoding = System.Text.Encoding.UTF7;
        Response.ContentType = "application/ms-excel";
        System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
        gvSelectorder.RenderControl(oHtmlTextWriter);
        Response.Output.Write(oStringWriter.ToString());
        Response.Flush();
        Response.End();
    }

这样写只能导出一个   如何才能全部导出 在一个excel里面？答案如下：

1、你把两个GridView放在一个div里，比如这样

<div runat="server" id="divExport">
  <gridview1 .....>
  <gridview2 .....>
</div>

2、然后后台 gvSelectorder.RenderControl(oHtmlTextWriter); 这句改成 divExport.RenderControl(oHtmlTextWriter); 试一下
