                    //Update Extension
                    if (result.sMessage == "1")
                    {

public JsonResult htmltopdf(string url,string inv)

        {

            // instantiate a html to pdf converter object

            HtmlToPdf converter = new HtmlToPdf(); 

            // create a new pdf document converting an url
            PdfDocument doc = converter.ConvertUrl(url); 

            // save pdf document

            doc.Save(Server.MapPath("~/upload/print/" + inv + ".pdf")); 

            // close pdf document

            doc.Close();

            return Json(new { sMessage = "11"}, JsonRequestBehavior.AllowGet); 

        }

 

[HttpPost]

        public JsonResult DeleteCommonFile(string path)
        {

            try
            {

                string filename = Server.MapPath(path);
                if (System.IO.File.Exists(filename))
                {

                    System.IO.File.Delete(filename);

                } 

                return Json(new { sMessage = "1", JsonRequestBehavior.AllowGet });

            }

            catch (Exception ex)
            {

                return Json(new { sMessage = ex.Message, JsonRequestBehavior.AllowGet });
