    protected override void Render(HtmlTextWriter writer)
    {
        System.IO.StringWriter html = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter tw = new HtmlTextWriter(html);
        base.Render(tw);
        System.IO.StreamWriter sw = new System.IO.StreamWriter(Server.MapPath("index.html"), false, System.Text.Encoding.UTF8);
        sw.Write(html.ToString());
        sw.Close();
        tw.Close();
        Response.Redirect("index.html");
