Add Header and Footer for PDF using iTextsharp

Question

How can I add header and footer for each page in the pdf.

Headed will contain just a text Footer will contain a text and pagination for pdf (Page : 1 of 4)

How is this possible ? I tried to add the below line, but header does not show up in pdf.

document.AddHeader("Header", "Header Text"); 

This the code I am using for generation PDF :

   protected void GeneratePDF_Click(object sender, EventArgs e)     {         DataTable dt = getData();               Response.ContentType = "application/pdf";             Response.AddHeader("content-disposition", "attachment;filename=Locations.pdf");             Response.Cache.SetCacheability(HttpCacheability.NoCache);              Document document = new Document();              PdfWriter.GetInstance(document, Response.OutputStream);              document.Open();              iTextSharp.text.Font font5 = iTextSharp.text.FontFactory.GetFont(FontFactory.COURIER , 8);              PdfPTable table = new PdfPTable(dt.Columns.Count);             PdfPRow row = null;             float[] widths = new float[] { 6f, 6f, 2f, 4f, 2f };              table.SetWidths(widths);              table.WidthPercentage = 100;             int iCol = 0;             string colname = "";             PdfPCell cell = new PdfPCell(new Phrase("Locations"));              cell.Colspan = dt.Columns.Count;              foreach (DataColumn c in dt.Columns)             {                  table.AddCell(new Phrase(c.ColumnName, font5));             }              foreach (DataRow r in dt.Rows)             {                 if (dt.Rows.Count > 0)                 {                     table.AddCell(new Phrase(r[0].ToString(), font5));                     table.AddCell(new Phrase(r[1].ToString(), font5));                     table.AddCell(new Phrase(r[2].ToString(), font5));                     table.AddCell(new Phrase(r[3].ToString(), font5));                     table.AddCell(new Phrase(r[4].ToString(), font5));                 }             }             document.Add(table);             document.Close();              Response.Write(document);             Response.End();         }      }

As already answered by @Bruno you need to use pageEvents.

Please check out the sample code below:

private void CreatePDF() {     string fileName = string.Empty;         DateTime fileCreationDatetime = DateTime.Now;         fileName = string.Format("{0}.pdf", fileCreationDatetime.ToString(@"yyyyMMdd") + "_" + fileCreationDatetime.ToString(@"HHmmss"));         string pdfPath = Server.MapPath(@"~\PDFs\") +   fileName;      using (FileStream msReport = new FileStream(pdfPath, FileMode.Create))     {         //step 1         using (Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 140f, 10f))         {             try             {                 // step 2                 PdfWriter pdfWriter = PdfWriter.GetInstance(pdfDoc, msReport);                 pdfWriter.PageEvent = new Common.ITextEvents();                  //open the stream                  pdfDoc.Open();                  for (int i = 0; i < 10; i++)                 {                     Paragraph para = new Paragraph("Hello world. Checking Header Footer", new Font(Font.FontFamily.HELVETICA, 22));                         para.Alignment = Element.ALIGN_CENTER;                         pdfDoc.Add(para);                         pdfDoc.NewPage();                 }                  pdfDoc.Close();                 }             catch (Exception ex)             {                 //handle exception             }                 finally             {              }             }         } } 

And create one class file named ITextEvents.cs and add following code:

public class ITextEvents : PdfPageEventHelper {         // This is the contentbyte object of the writer     PdfContentByte cb;      // we will put the final number of pages in a template     PdfTemplate headerTemplate, footerTemplate;      // this is the BaseFont we are going to use for the header / footer     BaseFont bf = null;      // This keeps track of the creation time     DateTime PrintTime = DateTime.Now;          #region Fields     private string _header;     #endregion      #region Properties     public string Header     {         get { return _header; }         set { _header = value; }     }     #endregion          public override void OnOpenDocument(PdfWriter writer, Document document)     {         try         {             PrintTime = DateTime.Now;             bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);             cb = writer.DirectContent;             headerTemplate = cb.CreateTemplate(100, 100);             footerTemplate = cb.CreateTemplate(50, 50);         }         catch (DocumentException de)         {             }         catch (System.IO.IOException ioe)         {             }     }      public override void OnEndPage(iTextSharp.text.pdf.PdfWriter writer, iTextSharp.text.Document document)     {         base.OnEndPage(writer, document);             iTextSharp.text.Font baseFontNormal = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 12f, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.BLACK);             iTextSharp.text.Font baseFontBig = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 12f, iTextSharp.text.Font.BOLD, iTextSharp.text.BaseColor.BLACK);             Phrase p1Header = new Phrase("Sample Header Here", baseFontNormal);          //Create PdfTable object         PdfPTable pdfTab = new PdfPTable(3);          //We will have to create separate cells to include image logo and 2 separate strings         //Row 1         PdfPCell pdfCell1 = new PdfPCell();         PdfPCell pdfCell2 = new PdfPCell(p1Header);         PdfPCell pdfCell3 = new PdfPCell();         String text = "Page " + writer.PageNumber + " of ";              //Add paging to header         {             cb.BeginText();             cb.SetFontAndSize(bf, 12);             cb.SetTextMatrix(document.PageSize.GetRight(200), document.PageSize.GetTop(45));             cb.ShowText(text);             cb.EndText();             float len = bf.GetWidthPoint(text, 12);             //Adds "12" in Page 1 of 12             cb.AddTemplate(headerTemplate, document.PageSize.GetRight(200) + len, document.PageSize.GetTop(45));         }         //Add paging to footer         {             cb.BeginText();             cb.SetFontAndSize(bf, 12);             cb.SetTextMatrix(document.PageSize.GetRight(180), document.PageSize.GetBottom(30));             cb.ShowText(text);             cb.EndText();             float len = bf.GetWidthPoint(text, 12);             cb.AddTemplate(footerTemplate, document.PageSize.GetRight(180) + len, document.PageSize.GetBottom(30));         }          //Row 2         PdfPCell pdfCell4 = new PdfPCell(new Phrase("Sub Header Description", baseFontNormal));          //Row 3          PdfPCell pdfCell5 = new PdfPCell(new Phrase("Date:" + PrintTime.ToShortDateString(), baseFontBig));         PdfPCell pdfCell6 = new PdfPCell();         PdfPCell pdfCell7 = new PdfPCell(new Phrase("TIME:" + string.Format("{0:t}", DateTime.Now), baseFontBig));              //set the alignment of all three cells and set border to 0         pdfCell1.HorizontalAlignment = Element.ALIGN_CENTER;         pdfCell2.HorizontalAlignment = Element.ALIGN_CENTER;         pdfCell3.HorizontalAlignment = Element.ALIGN_CENTER;

I hope it helps!
