Unable to Set PDF text colour with Itextsharp and c#

I am trying to set text colour of PDF using Itextsharp and c#.
Below is the snippet.
iTextSharp.text.pdf.PdfReader reader = new iTextSharp.text.pdf.PdfReader(sourcefilePath);
iTextSharp.text.pdf.PdfReader sReader = new iTextSharp.text.pdf.PdfReader(overlayfilePath);
PdfStamper stamper = new PdfStamper(reader, new FileStream(outputFile, FileMode.Create));
int inputDocumentPages = reader.NumberOfPages;
int overlayDocumentPages = sReader.NumberOfPages;
PdfContentByte background;
for (int i = 1; i <= inputDocumentPages; i++)
{
if (i <= overlayDocumentPages)
{
PdfImportedPage page = stamper.GetImportedPage(sReader, i);
background = stamper.GetUnderContent(i);
background.SetColorFill(BaseColor.RED);
background.Fill();
background.AddTemplate(page, 0, 0);
PdfGState state = new PdfGState();
state.FillOpacity = 0.6f;
state.BlendMode = PdfGState.BM_MULTIPLY;
background.SetGState(state);
background.SaveState();
}
}
stamper.Close();

iTextSharp.text.Font fontNormalBlack = iTextSharp.text.FontFactory.GetFont("Arial", 12, iTextSharp.text.Font.NORMAL, new BaseColor(Color.Blue));
iTextSharp.text.Font fontNormalBlue = iTextSharp.text.FontFactory.GetFont("Arial", 12, iTextSharp.text.Font.NORMAL, new BaseColor(Color.Black));
Document doc = new Document(PageSize.A4);
string caminho = appPath + "//data//temp//" + Guid.NewGuid().ToString() + ".pdf";
PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(caminho, FileMode.Create));
doc.SetMargins(70, 70, 70, 70);
doc.AddCreationDate();
doc.Open();
Paragraph paragrafo = new Paragraph();
paragrafo.Alignment = Element.ALIGN_LEFT;
paragrafo.Add(new Chunk("Name: ", fontNormalBlack));
paragrafo.Add(new Chunk("Paulo Muniz" + "\n\n", fontNormalBlue));
paragrafo.Add(new Chunk("Birthday: ", fontNormalBlack));
paragrafo.Add(new Chunk("24/07" + "\n", fontNormalBlue));
doc.Add(paragrafo);
doc.Close();

header and footer using itextsharp using c#

I am using itextsharp for pdf generation using .net web applications. I have installed the following version of itextsharp using nuget package Install-Package iTextSharp -Version 5.5.10. I have seen the samples and developed
code sample to generate the pdf and it is working. However i am not able to understand or get the header footer been added to the pdf. Here is the sample code i am using
public class Header : PdfPageEventHelper
{
protected Phrase header;
public void setHeader(Phrase header)
{
this.header = header;
}
public void onEndPage(PdfWriter writer, Document document)
{
PdfContentByte canvas = writer.DirectContent;
ColumnText.ShowTextAligned(canvas, Element.ALIGN_RIGHT, header, 559, 806, 0);
}
}
Document pdfReport = null;
MemoryStream msReport = new MemoryStream();
PdfWriter pdfWriter = PdfWriter.GetInstance(pdfReport, msReport);
if (!string.IsNullOrEmpty(HeaderText))
{
Header objHeaderFooter = new Header();
//Here i need to assign the string HeaderText to Header. I dont know how to do it.
}
Please help to know how to assign HeaderText using itextSharp. Most of the developers examples are on java
but i am using .net c#.

You want to assign HeaderText to objHeaderFooter in
if (!string.IsNullOrEmpty(HeaderText))
{
Header objHeaderFooter = new Header();
//Here i need to assign the string HeaderText to Header. I dont know how to do it.
}
Assuming HeaderText to be a string you can do so using the Header method setHeader:
objHeaderFooter.setHeader(new Phrase(HeaderText));
Furthermore, you have to assign objHeaderFooter to your PdfWriter instance:
pdfWriter.PageEvent = objHeaderFooter;
Thus:
if (!string.IsNullOrEmpty(HeaderText))
{
Header objHeaderFooter = new Header();
objHeaderFooter.setHeader(new Phrase(HeaderText));
pdfWriter.PageEvent = objHeaderFooter;
}
Furthermore, whenever you override a method in c#, mark it accordingly as override. In particular in your page event listener, use
public override void onEndPage(PdfWriter writer, Document document)
This is easy to forget, especially when porting java examples because in java the corresponding marker #Override is optional.
Below is the sample code provided by the op.
Response.Clear();
Response.Buffer = true;
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment; filename=abc.pdf");
Response.Charset = "";
Response.BinaryWrite(getbinary());
Response.End();
public byte[] getbinary()
{
Document pdfReport = null;
pdfReport = new Document(PageSize.A4, 25, 25, 40, 25);
MemoryStream msReport = new MemoryStream();
PdfWriter pdfWriter = PdfWriter.GetInstance(pdfReport, msReport);
pdfReport.Open();
if (!string.IsNullOrEmpty("Header Text"))
{
Header objHeaderFooter = new Header();
objHeaderFooter.SetHeader(new Phrase("Header Text"));
pdfWriter.PageEvent = objHeaderFooter;
}
PdfPTable ptData1 = new PdfPTable(1);
ptData1.SpacingBefore = 8;
ptData1.DefaultCell.Padding = 1;
ptData1.WidthPercentage = 100;
ptData1.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER;
ptData1.DefaultCell.VerticalAlignment = Element.ALIGN_MIDDLE;
PdfPCell cell1 = new PdfPCell();
cell1.BorderWidth = 0.001F;
cell1.BackgroundColor = new BaseColor(250, 250, 250);
cell1.BorderColor = new BaseColor(100, 100, 100);
cell1.Phrase = new Phrase("Sample text");
ptData1.AddCell(cell1);
PdfPCell cell = new PdfPCell();
cell.BorderWidth = 0.001F;
cell.BackgroundColor = new BaseColor(200, 200, 200);
cell.BorderColor = new BaseColor(100, 100, 100);
cell.Phrase = new Phrase("test value");
ptData1.AddCell(cell);
pdfReport.Add(ptData1);
pdfReport.Close();
return msReport.ToArray();
}
public class Header : PdfPageEventHelper
{
protected Phrase header;
public void SetHeader(Phrase header)
{
this.header = header;
}
public void onEndPage(PdfWriter writer, Document document)
{
PdfContentByte canvas = writer.DirectContent;
ColumnText.ShowTextAligned(canvas, Element.ALIGN_RIGHT, header, 559, 806, 0);
}
}

May be this could be used as a workaround. Added header as another cell value
Below is the code
if (!string.IsNullOrEmpty(HeaderText))
{
PdfPTable Header = new PdfPTable(1);
Header.SpacingBefore = 8;
Header.DefaultCell.Padding = 1;
Header.WidthPercentage = 100;
Header.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER;
Header.DefaultCell.VerticalAlignment = Element.ALIGN_MIDDLE;
PdfPCell cell1 = new PdfPCell();
cell1.BorderWidth = 0.001F;
cell1.BackgroundColor = new BaseColor(250, 250, 250);
cell1.BorderColor = new BaseColor(100, 100, 100);
cell1.Phrase = new Phrase(HeaderText, fontBold);
Header.AddCell(cell1);
pdfReport.Add(ptDataHeader);
}

Cannot access a non-static member of outer type 'System.Web.UI.Page' via nested type 'PrintToPdf._events'

I have been trying to add an image to all pages using iTextSharp.
According to this web page I need to look into the PdfPageEventHelper of iTextSharp.
It provides a method called OnEndPage that allows such things.
Basically, treat the image as being in the header or footer of the document, and use absolute positioning to put it where you want, instead of just in the flow of the page content.
The below code response with error :
Cannot access a non-static member of outer type 'System.Web.UI.Page'
via nested type 'PrintToPdf._events'
On :
PdfPCell cell2 = new PdfPCell(Image.GetInstance(Server.MapPath(imagepath)));
Is there any way to insert the image in the same way in all pages?
Can you help me ?
Thank you in advance.

itextsharp pdf not showing

I am using the following code to generate a PDF using iTextSharp from a GridView however the generated PDF is not visible to me. How can I view it in my html page?
GridView1.Visible = false;
SqlConnection sql = Connection.con();
sql.Open();
SqlCommand cmd = new SqlCommand("spGetSalesbyCustomer", sql);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("#CustomerId", Convert.ToInt32(TextBox1.Text));

iTextSharp.text.pdf.PdfPTable table = new iTextSharp.text.pdf.PdfPTable(cellCount);
int[] widths = new int[cellCount];
for (int x = 0; x < cellCount; x++)
{
widths[x] = (int)GridView2.Columns[x].ItemStyle.Width.Value;
string cellText = Server.HtmlDecode(GridView2.HeaderRow.Cells[x].Text);
//Set Font and Font Color
iTextSharp.text.Font font = new iTextSharp.text.Font(bf, 10, iTextSharp.text.Font.NORMAL);
//font.Color = new Color(GridView2.HeaderStyle.ForeColor);
iTextSharp.text.pdf.PdfPCell cell = new iTextSharp.text.pdf.PdfPCell(new Phrase(12, cellText, font));
//Set Header Row BackGround Color
//cell.BackgroundColor = new Color(GridView2.HeaderStyle.BackColor);
table.AddCell(cell);
}
table.SetWidths(widths);
for (int i = 0; i < GridView2.Rows.Count; i++)
{
if (GridView2.Rows[i].RowType == DataControlRowType.DataRow)
{
for (int j = 0; j < GridView2.Columns.Count; j++)
{
string cellText = Server.HtmlDecode(GridView2.Rows[i].Cells[j].Text);
//Set Font and Font Color
iTextSharp.text.Font font = new iTextSharp.text.Font(bf, 10, iTextSharp.text.Font.NORMAL);

Response.Write(pdfDoc);
Response.End();

Your question is a little unclear but if your code is correct (and I know it isn't 100% based on the seventh last line) then you're not actually adding your PdfPTable to the Document:
//Create the PDF Document
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
//Bind a writer to our document abstraction and our output stream
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
//Open the document for writing
pdfDoc.Open();
//This next line is a syntax error
//int pages = pdfDoc.;
//Add the table to the PDF
pdfDoc.Add(table);
//Close the document
pdfDoc.Close();
//ASP.Net/HTTP stuff
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
//Do not use this next line, it doesn't do what you think it does
//Response.Write(pdfDoc);
Response.End();

Document.NewPage giving object referance not set to an instance of an object

I'm new to creating pdfs, and successfully had one working but no footer, so I've been looking around and based myself on this
This is the code I have of it:
string nome = "MapaAnual" + DateTime.Now.Year.ToString() + "_" + DateTime.Now.Month.ToString() + "" + DateTime.Now.Day.ToString() + ".pdf";
string outputFile = "C:\\Users\\sies4578\\Documents\\Visual Studio 2012\\Projects\\ULSM_Equipamentos\\REL\\" + nome.ToString();
try
{
//Create a standard .Net FileStream for the file, setting various flags
//FileStream fs = new FileStream(outputFile, FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.ReadWrite);
System.IO.FileStream fs = new System.IO.FileStream(outputFile + DateTime.Now.ToString("ddMMyyHHmmss") + ".pdf", System.IO.FileMode.OpenOrCreate);
//Create a new PDF document setting the size to A4
Document doc = new Document(PageSize.A4.Rotate());
//Bind the PDF document to the FileStream using an iTextSharp PdfWriter
PdfWriter w = PdfWriter.GetInstance(doc, fs);
w.PageEvent = new MyPageEventHandler();
//Open the document for writing
doc.Open();
for (int i = 0; i < listaServicos.Count; i++)
{
doc.NewPage(); //where it goes to the catch giving that error
#region Calibracoes
//Code that doesn't matter
#endregion
}
doc.Close();
Process.Start(outputFile);
return "PDF criado com sucesso";
}

Console.WriteLine("An error ocurred, the PDF-document could not be created.");
