使用控件的  RenderControl（）方法生成HTML表格

       string strName = "HuaMingCe";
        Response.Clear();
        Response.Buffer = true;
        Response.Charset = "utf-8";
        Response.AppendHeader("Content-Disposition", "attachment;filename=" + strName + ".xls");
        Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");//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);
        if (GridViewMaster != null) //GridViewMaster 是GridView控件
        {
            GridViewMaster.RenderControl(oHtmlTextWriter);//将服务器控件的内容输出
        }
        Response.Write(oStringWriter.ToString());
        Response.End();

同时  vs2005会报错“类型“ExGridView”的控件“GridViewMaster”必须放在具有   runat=server   的窗体标记内

需要添加下面取消对  GridViewMaster   控件验证的方法

public override void VerifyRenderingInServerForm(Control control)
    {
        if (!control.GetType().Equals(GridViewMaster.GetType()))
        {
            base.VerifyRenderingInServerForm(control);
        }
    }
