Create Simple PDF File Using iTextSharp Library

iTextSharp


iTextSharp is a library that allows you to create and manipulate PDF documents.

It enables developers looking to enhance web applications and other applications with dynamic PDF document generation and/or manipulation.

Before proceeding you should have the iTextSharp library file.

You can download the iTextSharp.dll from here.
  1. Open VisualStudio and then create a new ASP.NET web application.
  2. Add a reference to the iTextSharp.dll file to your project.
  3. Add the following namespaces before proceeding:
    1. using System;  
    2. using iTextSharp.text.pdf;  
    3. using System.IO;  
    4. using iTextSharp.text;  
    5. using System.Diagnostics;  
  4. In the designer, drag and drop two buttons as follows,

  5. For the Generate PDF File button, write the following code to generate the PDF file:
    1. protected void btnGeneratePDFFile_Click(object sender, EventArgs e) {  
    2.     //Create document  
    3.     Document doc = new Document();  
    4.     //Create PDF Table  
    5.     PdfPTable tableLayout = new PdfPTable(4);  
    6.     //Create a PDF file in specific path  
    7.     PdfWriter.GetInstance(doc, new FileStream(Server.MapPath("Sample-PDF-File.pdf"), FileMode.Create));  
    8.     //Open the PDF document  
    9.     doc.Open();  
    10.     //Add Content to PDF  
    11.     doc.Add(Add_Content_To_PDF(tableLayout));  
    12.     // Closing the document  
    13.     doc.Close();  
    14.     btnOpenPDFFile.Enabled = true;  
    15.     btnGeneratePDFFile.Enabled = false;  
    16. }  
    17. private PdfPTable Add_Content_To_PDF(PdfPTable tableLayout) {  
    18.     float[] headers = {  
    19.         20,  
    20.         20,  
    21.         30,  
    22.         30  
    23.     }; //Header Widths  
    24.     tableLayout.SetWidths(headers); //Set the pdf headers  
    25.     tableLayout.WidthPercentage = 80; //Set the PDF File witdh percentage  
    26.     //Add Title to the PDF file at the top  
    27.     tableLayout.AddCell(new PdfPCell(new Phrase("Creating PDF file using iTextsharp"new Font(Font.HELVETICA, 13, 1, new iTextSharp.text.Color(153, 51, 0)))) {  
    28.         Colspan = 4, Border = 0, PaddingBottom = 20, HorizontalAlignment = Element.ALIGN_CENTER  
    29.     });  
    30.     //Add header  
    31.     AddCellToHeader(tableLayout, "Cricketer Name");  
    32.     AddCellToHeader(tableLayout, "Height");  
    33.     AddCellToHeader(tableLayout, "Born On");  
    34.     AddCellToHeader(tableLayout, "Parents");  
    35.     //Add body  
    36.     AddCellToBody(tableLayout, "Sachin Tendulkar");  
    37.     AddCellToBody(tableLayout, "1.65 m");  
    38.     AddCellToBody(tableLayout, "April 24, 1973");  
    39.     AddCellToBody(tableLayout, "Ramesh Tendulkar, Rajni Tendulkar");  
    40.     AddCellToBody(tableLayout, "Mahendra Singh Dhoni");  
    41.     AddCellToBody(tableLayout, "1.75 m");  
    42.     AddCellToBody(tableLayout, "July 7, 1981");  
    43.     AddCellToBody(tableLayout, "Devki Devi, Pan Singh");  
    44.     AddCellToBody(tableLayout, "Virender Sehwag");  
    45.     AddCellToBody(tableLayout, "1.70 m");  
    46.     AddCellToBody(tableLayout, "October 20, 1978");  
    47.     AddCellToBody(tableLayout, "Aryavir Sehwag, Vedant Sehwag");  
    48.     AddCellToBody(tableLayout, "Virat Kohli");  
    49.     AddCellToBody(tableLayout, "1.75 m");  
    50.     AddCellToBody(tableLayout, "November 5, 1988");  
    51.     AddCellToBody(tableLayout, "Saroj Kohli, Prem Kohli");  
    52.     return tableLayout;  
    53. }  
    54. // Method to add single cell to the header  
    55. private static void AddCellToHeader(PdfPTable tableLayout, string cellText) {  
    56.     tableLayout.AddCell(new PdfPCell(new Phrase(cellText, new Font(Font.HELVETICA, 8, 1, iTextSharp.text.Color.WHITE))) {  
    57.         HorizontalAlignment = Element.ALIGN_CENTER, Padding = 5, BackgroundColor = new iTextSharp.text.Color(0, 51, 102)  
    58.     });  
    59. }  
    60. // Method to add single cell to the body  
    61. private static void AddCellToBody(PdfPTable tableLayout, string cellText) {  
    62.     tableLayout.AddCell(new PdfPCell(new Phrase(cellText, new Font(Font.HELVETICA, 8, 1, iTextSharp.text.Color.BLACK))) {  
    63.         HorizontalAlignment = Element.ALIGN_CENTER, Padding = 5, BackgroundColor = iTextSharp.text.Color.WHITE  
    64.     });  
    65. }  
    Don't be confused by the code above, I am extracting the methods for reusability purposes.

    I will explain whats happening in the preceding methods.

    btnGeneratePDFFile_Click
    In this method I am creating the PDF file in a specific location. Then I am calling the Add_Content_To_PDF method.

    Add_Content_To_PDF
    In this method I am giving the sizes of the cells as well as PDF file width and then I am adding content to the PDF file usigng the two methods AddCellToHeader and AddCellToBody.

    AddCellToHeader
    In this mehtod I am adding a single cell to the PDF header with some style.

    AddCellToBody
    In this mehtod I am adding a single cell to the PDF body with some style. 

  6. Now in the Open PDF button click write the following code to open the PDF that has been created:
    1. protected void btnOpenPDFFile_Click(object sender, EventArgs e)  
    2. {  
    3.     //Open the PDF file  
    4.     Process.Start(Server.MapPath("Sample-PDF-File.pdf"));  
    5.     btnGeneratePDFFile.Enabled = true;  
    6.     btnOpenPDFFile.Enabled = false;  
    7. }  
  7. Save the files and run the project. Click on Generate PDF; your PDF file will be generated. Then click on the Open PDF file, you will get the created PDF.

  8. If your code is not working then I have added a project to this article you can download and test. 
So in this way we can create a PDF simply by using the iTextSharp library.
