            PdfWriter.GetInstance(pdfDoc, System.Web.HttpContext.Current.Response.OutputStream);

            //Open PDF Document to write data
            pdfDoc.Open();

            //Assign Html content in a string to write in PDF
            string contents = "";

            StreamReader sr;
            try
            {
                //Read file from server path
                sr = File.OpenText(Server.MapPath("~/Forms/Payment_Details/HTMLPage/ChallanCheckList.htm"));
                //store content in the variable
                contents = sr.ReadToEnd();

            var parsedHtmlElements = HTMLWorker.ParseToList(new StringReader(contents), null);

            //Get each array values from parsed elements and add to the PDF document
            foreach (var htmlElement in parsedHtmlElements)
                pdfDoc.Add(htmlElement as IElement);
            
            Response.ContentType = "application/pdf";
            ContentDisposition cd = new ContentDisposition
