Generate Footer Content using ITextSharp

ITextSharp provides the Pdfpageeventhandler class to handle the event at the time to generate pdf file. If you want to handle the event on start of page

or when close the pdf then inherit your class with Pdfpageeventhandler.

If you want to display footer on every page then can do this in OnEndPage event.

Below are the sample code to display content in footer

   public override void OnEndPage(PdfWriter writer, Document document)

        {

            base.OnEndPage(writer, document);

            PdfTemplate tmpFooter = pdfContent.CreateTemplate(600, 300);

             tmpFooter.MoveTo(1, 1);

            // Place the footer content

            tmpFooter.Stroke();

            // Begin writing the footer

            tmpFooter.BeginText();

          // Bold text for ther headers

            tmpFooter.SetFontAndSize(boldFont, 9);

            tmpFooter.ShowTextAligned(PdfContentByte.ALIGN_LEFT, "Total: ", 400, 80, 0);

            // Regular text for infomation fields

            tmpFooter.SetFontAndSize(baseFont, 9);

            tmpFooter.ShowTextAligned(PdfContentByte.ALIGN_LEFT, "$" + Total, 500, 80, 0);

            int pageN = writer.PageNumber;

            String text =  pageN + " of " + TotalPages;

            float len = baseFont.GetWidthPoint(text, 8);

            Rectangle pageSize = document.PageSize;

            pdfContent = writer.DirectContent;

            tmpFooter.SetFontAndSize(boldFont, 8);

            tmpFooter.SetTextMatrix(pageSize.GetLeft(440), pageSize.GetBottom(10));

            tmpFooter.ShowText(text);

            // End text

            tmpFooter.EndText();

            // Stamp a line above the page footer

            pdfContent.SetLineWidth(0f);

            pdfContent.MoveTo(20, 100);

            pdfContent.LineTo(580, 100);

            pdfContent.Stroke();

            pdfContent.AddTemplate(tmpFooter, 30, 1);

        }
