Get total number of pages in iTextsharp PDF C#

I am using iTextSharp for pdf generating purpose . I want to get page no with total page show on footer.
my code is-
public class footer : PdfPageEventHelper
{
public override void OnEndPage(PdfWriter writer, Document doc)
{
PdfPTable footerTbl = new PdfPTable(1);
footerTbl.TotalWidth = doc.PageSize.Width;
Chunk myFooter = new Chunk("Page " + (doc.PageNumber) + " of " + doc.PageCount, FontFactory.GetFont(FontFactory.HELVETICA_OBLIQUE, 8, grey))
PdfPCell footer = new PdfPCell(new Phrase(myFooter));
footer.Border = Rectangle.NO_BORDER;
footer.HorizontalAlignment = Element.ALIGN_RIGHT;
footerTbl.AddCell(footer);
footerTbl.WriteSelectedRows(0, -1, 0, (doc.BottomMargin + 10), writer.DirectContent);
}
doc.PageCount is give an error

you need to extent ITextEvents class that extends PdfPageEventHelper to add footer. in following way.
public class footer : PdfPageEventHelper
{
// This is the contentbyte object of the writer
PdfContentByte cb;
// we will put the final number of pages in a template
PdfTemplate footerTemplate;
// this is the BaseFont we are going to use for the header / footer
BaseFont bf = null;
public override void OnOpenDocument(PdfWriter writer, Document document)
{
try
{
bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
cb = writer.DirectContent;
footerTemplate = cb.CreateTemplate(50, 50);
}
catch (DocumentException de)
{
//handle exception here
}
catch (System.IO.IOException ioe)
{
//handle exception here
}
}
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 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));
}
pdfTab.TotalWidth = document.PageSize.Width - 80f;
pdfTab.WidthPercentage = 70;
}
public override void OnCloseDocument(PdfWriter writer, Document document)
{
base.OnCloseDocument(writer, document);
footerTemplate.BeginText();
footerTemplate.SetFontAndSize(bf, 12);
footerTemplate.SetTextMatrix(0, 0);
footerTemplate.ShowText((writer.PageNumber - 1).ToString());
footerTemplate.EndText();
}
}

how to add footer (with variables/class) with itextsharp pdf

I have this code and I want to add a table as a footer. But the problem is I cannot pass the variables:
Document doc = new Document();
doc.AddTitle("e-8D Report_" + report.OSIE8DNO + ".pdf");
PdfWriter writer = PdfWriter.GetInstance(doc, fs);
doc.SetPageSize(PageSize.A4);
doc.SetMargins(18f, 18f, 18f, 18f); // 0.25 inch margins
doc.Open();
PdfPTable table = new PdfPTable(10)
{
WidthPercentage = 100,
LockedWidth = true,
TotalWidth = 560f
};
float[] widths = new float[] { 32f, 73f, 70f, 70f, 70f, 70f, 70f, 70f, 73f, 32f };
table.SetWidths(widths);
// rest of the document
// ...
// rest of the document
// Below is the part that I want to add as footer
#region Footer
// left margin
cell = new PdfPCell(new Phrase(" ", font6))
{
Border = Rectangle.NO_BORDER
};
table.AddCell(cell);
cell = new PdfPCell(new Phrase("Reviewed & Approved by :", font6))
{
Colspan = 4,
BackgroundColor = bgBlue,
HorizontalAlignment = Element.ALIGN_LEFT,
Border = Rectangle.TOP_BORDER | Rectangle.LEFT_BORDER
};
table.AddCell(cell);
cell = new PdfPCell(new Phrase("For document approval by email, no Manual / e-Signature required &", font2))
{
Colspan = 4,
BackgroundColor = bgBlue,
HorizontalAlignment = Element.ALIGN_LEFT,
Border = Rectangle.TOP_BORDER | Rectangle.RIGHT_BORDER
};
table.AddCell(cell);
// right margin
cell = new PdfPCell(new Phrase(" ", font6))
{
Border = Rectangle.NO_BORDER
};
table.AddCell(cell);
// the rest of the cell
//...
// the rest of the cell
#endregion
doc.Add(table);
//writer.PageEvent = new PDFFooter();
doc.Close();
With this variables, I can't make the footer with PdfPageEventHelper from this source:
Footer in pdf with iTextSharp
Please help

Already got the answer. I add parameter to the PdfPageEventHelper Class:
public PdfPTable footer { get; set; }
public override void OnEndPage(PdfWriter writer, Document document)
{
base.OnEndPage(writer, document);
document.Add(footer);
}
And call from the page (create complete table first on the page):
writer.PageEvent = new PDFHeaderFooter() { footer = table };

how to add background color to last line of GridView

I tried using: GridView1.Rows[GridView1.Rows.Count - 1] to get the last row of gridview. But, I did not seem to make my way around it, to add color to last row.
Any help much appreciated.

You can simply do this:
GridView1.Rows[GridView1.Rows.Count - 1].BackColor = Color.Green;
Or if the row is a FooterRow:
GridView1.FooterRow.BackColor = Color.Red;

Generating PDF from a DataGridView in Winforms

I'm attempting to create a PDF from a DataGridView populated from a database.
I have just started trying to learn how to use iTextSharp to accomplish this.
The result of my code is a PDF that will not open. I get an error saying "File cannot be opened"
Here is my code to generate the PDF
void SendToPDF(string heading, string filename)
{
try
{
Document doc = new Document(PageSize.A4.Rotate(), 30, 30, 20, 20);
string myDocs = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
if (!Directory.Exists(myDocs + #"\Production Reports"))
Directory.CreateDirectory(myDocs + #"\Production Reports");
PdfWriter.GetInstance(doc, new FileStream(myDocs + #"\Production Reports\" + filename + ".pdf", FileMode.Append, FileAccess.Write));
iTextSharp.text.Font titleFont = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 14.0F, iTextSharp.text.Font.BOLD, BaseColor.BLACK);
iTextSharp.text.Font tableFont = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 12.0F, iTextSharp.text.Font.NORMAL, BaseColor.BLACK);
iTextSharp.text.Font headerfont = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 12.0F, iTextSharp.text.Font.BOLD, BaseColor.BLACK);
PdfPTable table = new PdfPTable(GridView.Columns.Count);
//table.TotalWidth = GridView.Width;
//There are ALWAYS 10 columns
float[] widths = new float[] { GridView.Columns[0].Width, GridView.Columns[1].Width, GridView.Columns[2].Width,
GridView.Columns[3].Width, GridView.Columns[4].Width, GridView.Columns[5].Width,
GridView.Columns[6].Width, GridView.Columns[7].Width, GridView.Columns[8].Width,
GridView.Columns[9].Width };
table.SetWidths(widths);
table.HorizontalAlignment = 1; // 0 - left, 1 - center, 2 - right;
table.SpacingBefore = 2.0F;
PdfPCell cell = null;
doc.Open();
Phrase p = new Phrase(new Chunk(heading, titleFont));
doc.Add(p);
foreach (DataGridViewColumn c in GridView.Columns)
{
cell = new PdfPCell(new Phrase(new Chunk(c.HeaderText, headerfont)));
cell.HorizontalAlignment = PdfPCell.ALIGN_CENTER;
cell.VerticalAlignment = PdfPCell.ALIGN_CENTER;
table.AddCell(cell);
}
if (GridView.Rows.Count > 0)
{
for (int i = 0; i < GridView.Rows.Count - 1; i++)
{
for (int j = 0; j < GridView.Columns.Count - 1; j++)
{
cell = new PdfPCell(new Phrase(GridView.Rows[i].Cells[j].Value.ToString(), tableFont));
cell.HorizontalAlignment = PdfPCell.ALIGN_CENTER;
cell.VerticalAlignment = PdfPCell.ALIGN_CENTER;
table.AddCell(cell);
}
}
}
doc.Add(table);
doc.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message + "\r\n" + ex.StackTrace, "Error Generating PDF", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
I'm guessing my problem has to do with setting column widths, but I'm not sure. One time, and only one time..I saw an error when I tried to open the PDF that said "illegal floating point division by 0" or something along those lines.
Any help is greatly appreciated.

It may sound obvious, but your program isn't running and locking the pdf file to its process thus preventing adobe pdf reader from reading it is it?

private void jbtnPdf_Click(object sender, EventArgs e)
{
try
{
SaveFileDialog saveFileDialog = new SaveFileDialog();
saveFileDialog.Filter = "All Files | *.* ";
if (saveFileDialog.ShowDialog() == DialogResult.OK)
{
string path = saveFileDialog.FileName;
Document pdfdoc = new Document(PageSize.A4); // Setting the page size for the PDF
PdfWriter writer = PdfWriter.GetInstance(pdfdoc, new FileStream(path + ".pdf", FileMode.Create)); //Using the PDF Writer class to generate the PDF
writer.PageEvent = new PDFFooter();
// Opening the PDF to write the data from the textbox
PdfPTable table = new PdfPTable(jdgvChild.Columns.Count);
//table.TotalWidth = GridView.Width;
float[] widths = new float[] { jdgvChild.Columns[0].Width, jdgvChild.Columns[1].Width, jdgvChild.Columns[2].Width,
jdgvChild.Columns[3].Width, jdgvChild.Columns[4].Width, jdgvChild.Columns[5].Width,
jdgvChild.Columns[6].Width, jdgvChild.Columns[7].Width};
table.SetWidths(widths);
table.HorizontalAlignment = 1; // 0 - left, 1 - center, 2 - right;
table.SpacingBefore = 2.0F;
PdfPCell cell = null;
pdfdoc.Open();
//doc.Open();
// Phrase p = new Phrase(new Chunk(heading, titleFont));
// doc.Add(p);
foreach (GridViewDataColumn c in jdgvChild.Columns)
{
cell = new PdfPCell(new Phrase(new Chunk(c.HeaderText)));
cell.HorizontalAlignment = PdfPCell.ALIGN_CENTER;
cell.VerticalAlignment = PdfPCell.ALIGN_CENTER;
table.AddCell(cell);
}
if (jdgvChild.Rows.Count > 0)
{
for (int i = 0; i < jdgvChild.Rows.Count; i++)
{
PdfPCell[] objcell = new PdfPCell[jdgvChild.Columns.Count];
for (int j = 0; j < jdgvChild.Columns.Count-1; j++)
{
cell = new PdfPCell(new Phrase(jdgvChild.Rows[i].Cells[j].Value.ToString()));
cell.HorizontalAlignment = PdfPCell.ALIGN_CENTER;
cell.VerticalAlignment = PdfPCell.ALIGN_CENTER;
// table.AddCell(cell);
//lstCells.Add(cell);
objcell[j] = cell;
}
PdfPRow newrow = new PdfPRow(objcell);
table.Rows.Add(newrow);

MessageBox.Show("Pdf Generation Successfully.");

iTextSharp PageNumber but not on first and last pages

I am trying to show the page number of my PDF pages, but I don`t want to show it on first and last pages, because they are covers.
I use this code:
public class PDFPage : iTextSharp.text.pdf.PdfPageEventHelper
{
//I create a font object to use within my footer
protected iTextSharp.text.Font footer
{
get
{
// create a basecolor to use for the footer font, if needed.
iTextSharp.text.Color grey = new iTextSharp.text.Color(40, 40, 40);
Font font = FontFactory.GetFont("Arial", 16, iTextSharp.text.Font.BOLD, grey);
return font;
}
}
//override the OnPageEnd event handler to add our footer
public override void OnEndPage(PdfWriter writer, Document doc)
{
if (doc.PageNumber > 1)
{
//I use a PdfPtable with 2 columns to position my footer where I want it
PdfPTable footerTbl = new PdfPTable(2);
//set the width of the table to be the same as the document
footerTbl.TotalWidth = doc.PageSize.Width;
//Center the table on the page
footerTbl.HorizontalAlignment = Element.ALIGN_CENTER;
//Create a paragraph that contains the footer text
Paragraph para = new Paragraph(" ", footer);
//add a carriage return
para.Add(Environment.NewLine);
para.Add(" ");
//create a cell instance to hold the text
PdfPCell cell = new PdfPCell(para);
//set cell border to 0
cell.Border = 0;
//add some padding to bring away from the edge
cell.PaddingLeft = 10;
//add cell to table
footerTbl.AddCell(cell);
//create new instance of Paragraph for 2nd cell text
para = new Paragraph(" " + doc.PageNumber, footer);
//create new instance of cell to hold the text
cell = new PdfPCell(para);
//align the text to the right of the cell
cell.HorizontalAlignment = Element.ALIGN_LEFT;
//set border to 0
cell.Border = 0;
// add some padding to take away from the edge of the page
cell.PaddingRight = 10;
//add the cell to the table
footerTbl.AddCell(cell);
//write the rows out to the PDF output stream.
footerTbl.WriteSelectedRows(0, -1, 0, (doc.BottomMargin + 25), writer.DirectContent);
}
}
}
Thank you!

(writer.PageNumber - 1) is the last page. so check that too.

public class PageEventHelper : PdfPageEventHelper
{
PdfContentByte cb;
PdfTemplate template;
private int TotalNumber = 0;
//for remeber lastpage
public void SetNumber(int num)
{
TotalNumber = num;
}
public override void OnOpenDocument(PdfWriter writer, Document document)
{
cb = writer.DirectContent;
template = cb.CreateTemplate(50, 50);
}
public override void OnEndPage(PdfWriter writer, Document document)
{
base.OnEndPage(writer, document);
cb = writer.DirectContent;
template = cb.CreateTemplate(50, 50);
BaseFont font = BaseFont.CreateFont();
int pageN = writer.PageNumber;
String text = pageN.ToString();
float len = font.GetWidthPoint(text, 9);
iTextSharp.text.Rectangle pageSize = document.PageSize;
// cb.SetRGBColorFill(100, 100, 100);
;
cb.BeginText();
cb.SetFontAndSize(font, 9);
cb.SetTextMatrix(document.LeftMargin, pageSize.GetBottom(document.BottomMargin));
//cb.ShowText(text);
if (pageN > 1 && TotalNumber==0)
{
cb.ShowTextAligned(Element.ALIGN_CENTER, (pageN - 6).ToString() , 300f, 10f, 0);
}
cb.EndText();
cb.AddTemplate(template, document.LeftMargin + len, pageSize.GetBottom(document.BottomMargin));
}
}
And how to use the code ?
doc.Open();
//PdfWriter writer = PdfWriter.GetInstance(doc, stream);
PageEventHelper pageEventHelper = new PageEventHelper();
writer.PageEvent = pageEventHelper;
And before doc.closed()
Use the function SetNumber()
pageEventHelper.SetNumber(writer.PageNumber);
doc.Close();
you can use other number instead of the writer.PageNumber but not 0.
Hope this help you!
