Add pdfpTable at footer while creating PDF using iTextsharp

Question

In my Asp.net application i have to generate PDF so i did this using Itextsharp 4.0 which is free Open source,I refer this to set hearder/footer on the PDF generated,

but now my probelm is i am not able to add pdfPtable inside footer,any suggestion how to insert table at footer ?

Code On Page_Load

CreatePDF("Invoice", dtaddproduct, "Prince", "1313", "04/09/2013","4000");

On CreatePDF method i am calling

 TwoColumnHeaderFooter PageEventHandler = new TwoColumnHeaderFooter();
  writer.PageEvent = PageEventHandler;

before document.Open();

The custom HeaderFooter code (TwoColumnHeaderFooter):

    public override void OnStartPage(PdfWriter writer, Document document)
    {
    base.OnStartPage(writer, document);

    Rectangle pageSize = document.PageSize;

    if (Title != string.Empty)
    {
    cb.BeginText();
    cb.SetFontAndSize(bf, 15);
    cb.SetRGBColorFill(50, 50, 200);
    cb.SetTextMatrix(pageSize.GetLeft(40), pageSize.GetTop(40));
    cb.ShowText(Title);
    cb.EndText();
    }

    if (HeaderLeft + HeaderRight != string.Empty)
    {
    PdfPTable HeaderTable = new PdfPTable(4);
    HeaderTable.DefaultCell.VerticalAlignment = Element.ALIGN_MIDDLE;
    HeaderTable.TotalWidth = pageSize.Width - 80;
    HeaderTable.SetWidthPercentage(new float[] { 45, 45, 45, 45 }, pageSize);

    PdfPCell HeaderLeftCell = new PdfPCell(new Phrase(8, HeaderLeft, HeaderFont));
    HeaderLeftCell.Padding = 5;
    HeaderLeftCell.PaddingBottom = 8;
    HeaderLeftCell.BorderWidthRight = 1;
    HeaderTable.AddCell(HeaderLeftCell);

    PdfPCell HeaderRightCell = new PdfPCell(new Phrase(8, HeaderRight, HeaderFont));
    HeaderRightCell.HorizontalAlignment = PdfPCell.ALIGN_RIGHT;
    HeaderRightCell.Padding = 5;
    HeaderRightCell.PaddingBottom = 8;
    HeaderRightCell.BorderWidthLeft = 1;
    HeaderTable.AddCell(HeaderRightCell);

    cb.SetRGBColorFill(0, 0, 0);

    PdfPTable table = new PdfPTable(3);
    table.TotalWidth = document.PageSize.Width - document.LeftMargin - document.RightMargin;
    PdfPCell cell = new PdfPCell(new Phrase("Header spanning 3 columns"));
    cell.Colspan = 3;
    cell.HorizontalAlignment = 1; //0=Left, 1=Centre, 2=Right
    table.AddCell(cell);
   string billNumber = HttpContext.Current.Session["billlno"].ToString();
    string billDate = HttpContext.Current.Session["billdate"].ToString();
    string TotalRate = HttpContext.Current.Session["totalhours"].ToString();
    string customerName = HttpContext.Current.Session["customername"].ToString();
    table.AddCell("Date: " + billDate);
    table.AddCell("Bill No: " + billNumber);
    Chunk ck=new Chunk("one\ntwo\nthree\nfour");
     ck.SetBackground(Color.RED);
     Phrase p = new Phrase();
    p.Add(ck);
    PdfPCell cl = new PdfPCell();
    cl.AddElement(p);
    cl.BackgroundColor = new Color(0, 150, 0);
    table.AddCell(cl);
   table.AddCell("Total : "+TotalRate);
    table.AddCell("M/s : "+customerName);
    table.AddCell("Col 2 Row 2");
    table.AddCell("Col 3 Row 2");
    table.AddCell("Col 1 Row 3");
    table.AddCell("Col 2 Row 3");
    table.AddCell("Col 3 Row 3");
    table.WriteSelectedRows(0, -1, document.LeftMargin, document.PageSize.Height - 36, writer.DirectContent);
   }
    }

    public override void OnEndPage(PdfWriter writer, Document document)
    {
    base.OnEndPage(writer, document);

    int pageN = writer.PageNumber;
    String text = "Page " + pageN + " of ";
    float len = bf.GetWidthPoint(text, 8);
    Rectangle pageSize = document.PageSize;
    cb.SetRGBColorFill(100, 100, 100);

    cb.BeginText();
    cb.SetFontAndSize(bf, 8);
    cb.SetTextMatrix(pageSize.GetLeft(40), pageSize.GetBottom(30));
    cb.ShowText(text);
    cb.EndText();

    cb.AddTemplate(template, pageSize.GetLeft(40) + len, pageSize.GetBottom(30));
    cb.BeginText();
    cb.SetFontAndSize(bf, 8);
    cb.ShowTextAligned(PdfContentByte.ALIGN_RIGHT,
    "Printed On " + PrintTime.ToString(),
    pageSize.GetRight(40),
    pageSize.GetBottom(30), 0);
    cb.EndText();
    }

    public override void OnCloseDocument(PdfWriter writer, Document document)
    {
    base.OnCloseDocument(writer, document);
    template.BeginText();
    template.SetFontAndSize(bf, 8);
    template.SetTextMatrix(0, 0);
    template.ShowText("" + (writer.PageNumber - 1));
    template.EndText();
    }

Answer 1

Do not add content in OnStartPage, instead set variables in that and write them in OnEndPage. This is in the iText book but its hard to find online documentation beyond newsgroups that say this. See this and this

EDIT

@Satinder singh, that's a lot of code to read, if you can, always try to distill it down to the smallest amount of code that still breaks and remove any of your domain-specific stuff such as session and global variables. That said, I didn't read most of it but I think I spotted your problem:

PdfPTable table2 = new PdfPTable(3);
table2.TotalWidth = document.PageSize.Width - document.LeftMargin;
table2.AddCell("cell Value 1");
table2.AddCell("Cell Value 2 ");
table2.WriteSelectedRows(0, -1, document.LeftMargin + 200, document.PageSize.Height - 30, writer.DirectContent);

Above, you're creating a three column table but you're only add two cells to it. iTextSharp is a little picky about having the correct number of cells so either change it to a two column table or add a third cell.
