datagrid导出Excel 问题

Question

发觉在 模式窗体下DataGird导出没反应，普通的窗体下没有问题，不晓得大家怎么解决的。
导出代码：Response.Clear(); 
Response.Buffer= true; 
Response.Charset="GB2312";    
Response.AppendHeader("Content-Disposition","attachment;filename=FileName.xls"); 
Response.ContentEncoding=System.Text.Encoding.GetEncoding("GB2312");//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.dgProdzx.RenderControl(oHtmlTextWriter); 
Response.Write(oStringWriter.ToString());
Response.End();

Answer 3

页面增加一个按钮，单击事件添加如下方法：
protected void Button1_Click(object sender, EventArgs e)
    {
        Export("application/ms-excel", "学生成绩报表.xls");
    }    private void Export(string FileType, string FileName)
    {
        Response.Charset = "GB2312";
        Response.ContentEncoding = System.Text.Encoding.UTF7;
        Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
        Response.ContentType = FileType;
        this.EnableViewState = false;
        StringWriter tw = new StringWriter();
        HtmlTextWriter hw = new HtmlTextWriter(tw);
        GridView1.RenderControl(hw);
        Response.Write(tw.ToString());
        Response.End();
    }
//如果没有下面方法会报错类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内
    public override void VerifyRenderingInServerForm(Control control)
    {
    }
还有由于是文件操作所以要引入名称空间IO和Text后台代码：
using System;
using System.Data;
using System.Configuration;
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;
using System.Drawing;
using System.IO;
using System.Text;
public partial class Default7 : System.Web.UI.Page
{
    SqlConnection sqlcon;
    SqlCommand sqlcom;
    string strCon = "Data Source=(local);Database=北风贸易;Uid=sa;Pwd=sa";
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            bind();        }
    }
    
    public void bind()
    {
        string sqlstr = "select top 5 * from 飞狐工作室";
        sqlcon = new SqlConnection(strCon);
        SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
        DataSet myds = new DataSet();
        sqlcon.Open();
        myda.Fill(myds, "飞狐工作室");
        GridView1.DataSource = myds;
        GridView1.DataKeyNames = new string[] { "身份证号码" };
        GridView1.DataBind();
        sqlcon.Close();
    }    protected void Button1_Click(object sender, EventArgs e)
    {
        Export("application/ms-excel", "学生成绩报表.xls");
    }    private void Export(string FileType, string FileName)
    {
        Response.Charset = "GB2312";
        Response.ContentEncoding = System.Text.Encoding.UTF7;
        Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
        Response.ContentType = FileType;
        this.EnableViewState = false;
        StringWriter tw = new StringWriter();
        HtmlTextWriter hw = new HtmlTextWriter(tw);
        GridView1.RenderControl(hw);
        Response.Write(tw.ToString());
        Response.End();
    }
    public override void VerifyRenderingInServerForm(Control control)
    {
    }
    
}前台：
<asp:GridView ID="GridView1" runat="server"    AutoGenerateColumns="False" CellPadding="3" 
                         BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px"   >
                        <FooterStyle BackColor="White" ForeColor="#000066" />
                        <Columns>
                            <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />
                            <asp:BoundField DataField="姓名" HeaderText="姓名" />
                            <asp:BoundField DataField="出生日期" HeaderText="邮政编码" />
                            <asp:BoundField DataField="家庭住址" HeaderText="家庭住址" />
                            <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" />
                            <asp:BoundField DataField="起薪" HeaderText="起薪" />
                           
                        </Columns>
                        <RowStyle ForeColor="#000066" />
                        <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

                        <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
                    </asp:GridView>
        <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="导出" />读取Excel数据的代码：这个很简单的
private DataSet CreateDataSource()
    {
        string strCon;
        strCon = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("excel.xls") + "; Extended Properties=Excel 8.0;";
        OleDbConnection olecon = new OleDbConnection(strCon);
        OleDbDataAdapter myda = new OleDbDataAdapter("SELECT * FROM [Sheet1$]", strCon);
        DataSet myds = new DataSet();
        myda.Fill(myds);
        return myds;
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        GridView1.DataSource = CreateDataSource();
        GridView1.DataBind();
