Render Razor View to String and Generate PDF from using iTextSharp in ASP.NET MVC

Note:- 

Use NuGet Package Manager to download 

iTextSharp.dll and itextsharp.xmlworker.dll

Step 1: - Create following class in Models Folder

    public class ReceiptModel

    {

        public string Name { get; set; }

        public string Address { get; set; }

        public IEnumerable<ItemModel> Items { get; set; }

        public float GrossAmountTotal { get; set; }

        public float DiscountAmountTotal { get; set; }

        public float NetAmountTotal { get; set; }

    }

    public class ItemModel

    {

       public int SrNo { get; set; }

        public string Description { get; set; }

        public int Qty { get; set; }

        public float GrossAmount { get; set; }

        public float DiscountAmount { get; set; }

        public float NetAmount { get; set; }

    }

Step 2: - Create DemoController in Controller Folder and copy past following actions

        public ActionResult Index()

        {

            return View();

        }

        public ActionResult ExportToPDFWithoutModel()

        {

            string strData = RenderRazorViewToString(@"~\Views\Demo\ReceiptWithoutModelTemplate.cshtml");

            using (MemoryStream stream = new System.IO.MemoryStream())

            {

                StringReader sr = new StringReader(strData);

                Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 10f);

                PdfWriter writer = PdfWriter.GetInstance(pdfDoc, stream);

                pdfDoc.Open();

                XMLWorkerHelper.GetInstance().ParseXHtml(writer, pdfDoc, sr);

                pdfDoc.Close();

                return File(stream.ToArray(), "application/pdf", "Report.pdf");

            }

        }

        public ActionResult ExportToPDFWithModel()

        {

            ReceiptModel receiptModel = new ReceiptModel();

            receiptModel.Name = "Ram G";

            receiptModel.Address = "101, Eastern Plaza, Malad (east), Maharashtra, Mumbai-400097";

            receiptModel.Items = new List<ItemModel>

            {

                new ItemModel

                {

                    SrNo = 1,

                    Description = "Parle G 140g",

                    Qty = 12,

                   GrossAmount = 140,

                    DiscountAmount = 12,

                    NetAmount = 128

                },

                new ItemModel

                {

                    SrNo = 2,

                    Description = "Britannia 50-50 80g",

                    Qty = 6,

                    GrossAmount = 60,

                    DiscountAmount = 6,

                    NetAmount = 54

                },

                new ItemModel

                {

                    SrNo = 3,

                    Description = "Britannia Treat-Jim Jam 100g",

                    Qty = 3,

                    GrossAmount = 60,

                    DiscountAmount = 6,

                    NetAmount = 54

                },

                new ItemModel

                {

                    SrNo = 4,

                    Description = "Sunfeast Yippee Noodles-Magic Masala 280g",

                    Qty = 1,

                    GrossAmount = 45,

                    DiscountAmount = 1,

                    NetAmount = 44

                }

            };

            receiptModel.GrossAmountTotal = 305;

            receiptModel.DiscountAmountTotal = 25;

            receiptModel.NetAmountTotal = 280;

            string strData = RenderRazorViewToString(@"~\Views\Demo\ReceiptWithModelTemplate.cshtml", receiptModel);

            using (MemoryStream stream = new System.IO.MemoryStream())

            {

                StringReader sr = new StringReader(strData);

                Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 10f);

                PdfWriter writer = PdfWriter.GetInstance(pdfDoc, stream);

                pdfDoc.Open();

                XMLWorkerHelper.GetInstance().ParseXHtml(writer, pdfDoc, sr);

                pdfDoc.Close();

                return File(stream.ToArray(), "application/pdf", "Report.pdf");

            }

        }

        public string RenderRazorViewToString(string viewName, object model = null)

        {

            ViewData.Model = model;

            using (var sw = new StringWriter())

            {

                var viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);

                var viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);

                viewResult.View.Render(viewContext, sw);

                viewResult.ViewEngine.ReleaseView(ControllerContext, viewResult.View);

                return sw.GetStringBuilder().ToString();

            }

        }

Step 3: - Create Index.cshtml inside the Demo Folder i.e. reside in View Folder

    @Html.ActionLink("Export To PDF Without Model", "ExportToPDFWithoutModel", "Demo")

    @Html.ActionLink("Export To PDF With Model", "ExportToPDFWithModel", "Demo")

Step 4: - Create ReceiptWithoutModelTemplate.cshtml inside the Demo Folder i.e. reside in View Folder
