当页面为单独页面时，可以正常的导出数据，当把这个页面放在另一个页面的<iframe>标记中作为该页的子页面时，就不能导出数据了。各位高手帮帮忙哈
代码如下：
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;

public partial class Pages_gvdata : System.Web.UI.Page
{
public override void VerifyRenderingInServerForm(Control control)
{
// Confirms that an HtmlForm control is rendered for
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
clsDB db = new clsDB();
try
{
db.OpenConn();
SqlConnection con = db.conn;
SqlCommand cmd = new SqlCommand("select * from WIDC_SumBox", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
gv.DataSource = ds;
gv.DataBind();

}
catch(Exception ex)
{
clsCommon.showwarn(ex.Message);
}
finally
{
db.CloseConn();
}
}
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = false;
Response.Charset = "GB2312";
Response.AppendHeader("Content-Disposition", "attachment;filename=test.xls");
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
Response.ContentType = "application/ms-excel";
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
this.gv.RenderControl(oHtmlTextWriter);
Response.Write(oStringWriter.ToString());
Response.End();
}
}
页面：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="gvdata.aspx.cs" Inherits="Pages_gvdata" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
