Gridview导出EXCEL问题 急~~~！！！

Question

现在是做一个excel导出，但是导出后无数据，请问各位大侠该怎么解决  protected void Button2_Click(object sender, EventArgs e)
    {
        try
        {
            string time = System.DateTime.Now.ToString();
            this.Export("application/ms-excel", "" + time + ".xls");
        }
        catch
        { }
    }
    public override void VerifyRenderingInServerForm(Control control)
    {    }
    private void Export(string FileType, string FileName)
    {
        try
        {
            Response.Charset = "GB2312";
            Response.ContentEncoding = System.Text.Encoding.UTF8;
            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);
            GVSHOW.RenderControl(hw);
            Response.Write(tw.ToString());
            Response.End();        }
        catch 
        { }
    }
这段代码有的页面可以使用但是在新做的几个页面中就不能用了

Answer 1

GVSHOW.DataSource="你的数据源";
GVSHOW.DataBind();
GVSHOW.RenderControl(hw);
