private static readonly Regex REGEX_LINE_SPACE = new Regex(@"\n\s*\r", RegexOptions.Compiled);
private static readonly Regex REGEX_SPACE = new Regex(@"( )+", RegexOptions.Compiled);protected override void Render(HtmlTextWriter writer)

    using (HtmlTextWriter htmlwriter = new HtmlTextWriter(new System.IO.StringWriter()))
    {
        base.Render(htmlwriter);
        string html = htmlwriter.InnerWriter.ToString();
        html = REGEX_LINE_BREAKS.Replace(html, string.Empty);
        html = REGEX_LINE_SPACE.Replace(html, string.Empty);
