Im working in a project which requires current html page to convert in pdf and that pdf will automatically save on button click on server and its reference will be save in database.I can convert the view if its data comes from data base but the data in this form is static that means on the view it has so many radio button and text box in which i can write the detail and check the check box on after clicking save button it will save on the server and and its reference will save in the data base. the reason is that im not saving the data in database is that the report is less use full for the client but if i save the data in data base then the database become very huge and its become complicate to handle. because the report has approx 100 fields. so please if any one can help me in it.

Code for MVC looks like this:
[HttpPost] public ActionResult Convert(FormCollection collection) < // read parameters from the webpage string url = collection["TxtUrl"]; string pdf_page_size = collection["DdlPageSize"]; PdfPageSize pageSize = (PdfPageSize)Enum.Parse(typeof(PdfPageSize), pdf_page_size, true); string pdf_orientation = collection["DdlPageOrientation"]; PdfPageOrientation pdfOrientation = (PdfPageOrientation)Enum.Parse( typeof(PdfPageOrientation), pdf_orientation, true); int webPageWidth = 1024; try < webPageWidth = System.Convert.ToInt32(collection["TxtWidth"]); >catch < >int webPageHeight = 0; try < webPageHeight = System.Convert.ToInt32(collection["TxtHeight"]); >catch < >// instantiate a html to pdf converter object HtmlToPdf converter = new HtmlToPdf(); // set converter options converter.Options.PdfPageSize = pageSize; converter.Options.PdfPageOrientation = pdfOrientation; converter.Options.WebPageWidth = webPageWidth; converter.Options.WebPageHeight = webPageHeight; // create a new pdf document converting an url PdfDocument doc = converter.ConvertUrl(url); // save pdf document byte[] pdf = doc.Save(); // close pdf document doc.Close(); // return resulted pdf document FileResult fileResult = new FileContentResult(pdf, "application/pdf"); fileResult.FileDownloadName = "Document.pdf"; return fileResult; > public static Byte[] PdfSharpConvert(String html) < Byte[] res = null; using (MemoryStream ms = new MemoryStream()) < var pdf = TheArtOfDev.HtmlRenderer.PdfSharp.PdfGenerator.GeneratePdf(html, PdfSharp.PageSize.A4); pdf.Save(ms); res = ms.ToArray(); >return res; >

The C# code below can be used in a MVC application to convert the current view to PDF and produce a PDF in a buffer that can be saved on server or sent to browser for download. The code is using evopdf library for .net to perform the HTML to PDF conversion:
[HttpPost] public ActionResult ConvertCurrentPageToPdf(FormCollection collection) < object model = null; ViewDataDictionary viewData = new ViewDataDictionary(model); // The string writer where to render the HTML code of the view StringWriter stringWriter = new StringWriter(); // Render the Index view in a HTML string ViewEngineResult viewResult = ViewEngines.Engines.FindView(ControllerContext, "Index", null); ViewContext viewContext = new ViewContext( ControllerContext, viewResult.View, viewData, new TempDataDictionary(), stringWriter ); viewResult.View.Render(viewContext, stringWriter); // Get the view HTML string string htmlToConvert = stringWriter.ToString(); // Get the base URL String currentPageUrl = this.ControllerContext.HttpContext.Request.Url.AbsoluteUri; String baseUrl = currentPageUrl.Substring(0, currentPageUrl.Length - "Convert_Current_Page/ConvertCurrentPageToPdf".Length); // Create a HTML to PDF converter object with default settings HtmlToPdfConverter htmlToPdfConverter = new HtmlToPdfConverter(); // Convert the HTML string to a PDF document in a memory buffer byte[] outPdfBuffer = htmlToPdfConverter.ConvertHtml(htmlToConvert, baseUrl); // Send the PDF file to browser FileResult fileResult = new FileContentResult(outPdfBuffer, "application/pdf"); fileResult.FileDownloadName = "Convert_Current_Page.pdf"; return fileResult; >There is special nuget package RazorPDF. It simple works. RazorPDF site
