how to avoid pdf contents overlapping on Header and footer using itextsharp using C# code

[EDN Admin]

I want to display header and footer on every page of pdf, i am using itextsharp in C#.

I created class namely PdfPage which inherits PdfPageEventHelper
the code contains OnstartPage(for Header) OnEndPage(for Footer) namespace WebApplication2



{


public class PdfPage : iTextSharp.text.pdf.PdfPageEventHelper
{

public override void OnStartPage(PdfWriter writer, Document document)
{
string image2 = HttpContext.Current.Server.MapPath(".") + "/Images/developers_img.jpg";
string image3 = HttpContext.Current.Server.MapPath(".") + "/Images/contact_logo.png";
string imageFilePath = HttpContext.Current.Server.MapPath(".") + "/Images/contact_logo.png";


iTextSharp.text.Image jpg2 = iTextSharp.text.Image.GetInstance(image2);

iTextSharp.text.Image jpg3 = iTextSharp.text.Image.GetInstance(image3);

iTextSharp.text.Image jpg = iTextSharp.text.Image.GetInstance(imageFilePath);
jpg.ScaleToFit(280f, 400f);
jpg.Alignment = Element.ALIGN_TOP;
PdfPTable table1 = new PdfPTable(3);

table1.TotalWidth = document.PageSize.Width;

table1.WidthPercentage = 90;
//table1.HorizontalAlignment = Element.ALIGN_BOTTOM;

PdfPCell cell11 = new PdfPCell();
// cell11.PaddingLeft = 10;
cell11.AddElement(jpg);
cell11.Border = 0;
cell11.VerticalAlignment = Element.ALIGN_LEFT;

PdfPCell cell12 = new PdfPCell();
cell12.Border = 0;
PdfTemplate pdftm = writer.DirectContent.CreateTemplate(0,0);

PdfPCell cell13 = new PdfPCell();
cell13.AddElement(new Paragraph(""));
cell13.AddElement(new Paragraph(cellHeight+"Cell Height"));

cell13.AddElement(new Paragraph(" Last Updated"));

cell13.AddElement(new Paragraph(" " + DateTime.Now.ToString()));
cell13.Border = 0;


table1.AddCell(cell11);
table1.AddCell(cell12);
table1.AddCell(cell13);

document.Add(table1);






}

//Add the footer at the page end

public override void OnEndPage(PdfWriter writer, Document doc)
{


PdfPTable footerTbl = new PdfPTable(3);

footerTbl.TotalWidth = doc.PageSize.Width;
footerTbl.WidthPercentage = 90;



float cellHeight = doc.BottomMargin;
PdfPCell cell31 = new PdfPCell();
cell31.FixedHeight = cellHeight;
cell31.AddElement(new Paragraph(" "));
cell31.AddElement(new Paragraph(" "));
cell31.AddElement(new Paragraph(" "));
cell31.AddElement(new Paragraph(cellHeight+"Bottom margin "));
cell31.AddElement(new Paragraph("CONFIDENTIAL"));
cell31.AddElement(new Paragraph(" "));



cell31.Border = 0;

cell31.PaddingLeft = 10;
cell31.MinimumHeight = 100f;
footerTbl.AddCell(cell31);

PdfPCell cell32 = new PdfPCell();
cell32.Border = 0;
footerTbl.AddCell(cell32);

PdfPCell cell33 = new PdfPCell();
cell33.Border = 0;
//cell33.VerticalAlignment = Element.ALIGN_TOP;
//cell33.MinimumHeight = 100f;
cell33.PaddingBottom = 50;
cell33.AddElement(new Paragraph("Computer Solu, Inc."));
cell33.AddElement(new Paragraph("481 Main Street- 10801"));
cell33.AddElement(new Paragraph("Phone: 914 - 355 - 5800"));
cell33.AddElement(new Paragraph("www.computersolution.com"));

footerTbl.AddCell(cell33);



footerTbl.WriteSelectedRows(0, -1,0,footerTbl.TotalHeight, writer.DirectContent);
