Not sure if I skipped a step in my code, I am using ItextSharp version 5.5.1 and XML Worker version 5.5.1. When I open the pdf, it seems the like html has not been added in the creation. Here is the following code:

private void ExporttoPDF()
        {
            HttpContext.Current.Response.Clear();
            HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=RequestSummaryReport.pdf");
            HttpContext.Current.Response.Charset = "";
            HttpContext.Current.Response.ContentType = "application/pdf";

            StringWriter sw = new StringWriter();
            HtmlTextWriter htw = new HtmlTextWriter(sw);         

            var doc = new Document(PageSize.A3, 45, 5, 5, 5);
            PdfWriter writer = PdfWriter.GetInstance(doc, Response.OutputStream);

            doc.Open();

            HtmlPipelineContext htmlContext = new HtmlPipelineContext(null);
            htmlContext.SetTagFactory(Tags.GetHtmlTagProcessorFactory());
            ICSSResolver cssResolver = XMLWorkerHelper.GetInstance().GetDefaultCssResolver(false);

            IPipeline pipeline = new CssResolverPipeline(cssResolver, new HtmlPipeline(htmlContext, new PdfWriterPipeline(doc, writer)));

            XMLWorker worker = new XMLWorker(pipeline, true);
            XMLParser xmlParse = new XMLParser(true, worker);

            pnlReport.RenderControl(htw);
            StringReader sr = new StringReader(sw.ToString());
            xmlParse.Parse(sr);
            xmlParse.Flush();
            Response.Write(doc);
        }
