Hide column from datagridview in a pdf file

I have exported data from database to a datagridview and then to a pdf file and I want to delete one column in this file because it is a photo - I get only type of it in a cell (System.Byte[]).
I've tried to make my column invisible in datagridview but it didn't worked. It didn't have any impact on a pdf file, only column in datagridview had become hidden.
BaseFont bf = BaseFont.CreateFont(BaseFont.TIMES_ROMAN,
BaseFont.CP1250, BaseFont.EMBEDDED);
PdfPTable pdfTable = new PdfPTable(dgv.Columns.Count);
pdfTable.DefaultCell.Padding = 3;
pdfTable.WidthPercentage = 100;
pdfTable.HorizontalAlignment = Element.ALIGN_LEFT;
pdfTable.DefaultCell.BorderWidth = 1;
iTextSharp.text.Font text = new iTextSharp.text.Font(bf,10,iTextSharp.text.Font.NORMAL);
//Add header
foreach(DataGridViewColumn column in dgv.Columns)
{
PdfPCell cell = new PdfPCell(new Phrase(column.HeaderText, text));
cell.BackgroundColor = new iTextSharp.text.BaseColor(240, 240, 240);
pdfTable.AddCell(cell);
}
//add datarow
foreach(DataGridViewRow row in dgv.Rows)
{
foreach(DataGridViewCell cell in row.Cells)
{
//dgv.Columns[7].Visible = false;
pdfTable.AddCell(new Phrase(cell.Value.ToString(), text));
}
}
var savefiledialoge = new SaveFileDialog();
savefiledialoge.FileName = filename;
savefiledialoge.DefaultExt = ".pdf";
if(savefiledialoge.ShowDialog()==DialogResult.OK)
{
using(FileStream stream = new FileStream(savefiledialoge.FileName,FileMode.Create))
{
Document pdfdoc = new Document(PageSize.A4,10f,10f,10f,0f);
PdfWriter.GetInstance(pdfdoc, stream);
pdfdoc.Open();
pdfdoc.Add(pdfTable);
pdfdoc.Close();
stream.Close();
}
}

That's because even if you're making it invisible you still getting it in the loop
so you just need to make a condition in your loop to check if the column is visible or not
like this :
foreach(DataGridViewColumn column in dgv.Columns)
{
if (!column.Visible) continue;
PdfPCell cell = new PdfPCell(new Phrase(column.HeaderText, text));
cell.BackgroundColor = new iTextSharp.text.BaseColor(240, 240, 240);
pdfTable.AddCell(cell);
}
//add datarow
foreach(DataGridViewRow row in dgv.Rows)
{
foreach(DataGridViewCell cell in row.Cells)
{
if (!dgv.Columns[cell.ColumnIndex].Visible) continue;
//dgv.Columns[7].Visible = false;
pdfTable.AddCell(new Phrase(cell.Value.ToString(), text));
}
}
and now you can make your column to visible and it won't appear in the pdf file

phrase text too big for one page

I have a PDfTable like below, my problem is if Phrase text too big than it makes blank line between header and phrase. How can I bound together so if phrase text too big for one page than fit what ever text you can on the same page with headers and rest of the phrase text you can start with new page.
problem:
.............................
. header1 : header2 :header3: Page1 // here I want to fit the phrase as much as can if phrase needs new page than put rest of the text on the next page
. :
. phrase too big to fit here:
............................:
.............................
. phrase starts here . Page2
. .

cell.BackgroundColor = new iTextSharp.text.BaseColor(227, 234, 235);
cell.Colspan = 5;
pdfTable.AddCell(cell);
}
//String folderPath = ConfigurationManager.AppSettings["Path"].ToString();
String folderPath = "C:\\PDFs\\";
fileName = String.Format("{0}{1}{2}",folderPath, dt.Rows[0]["id"].ToString(),".pdf" );
//Exporting to PDF
if (!Directory.Exists(folderPath))
{
Directory.CreateDirectory(folderPath);
}
using (FileStream stream = new FileStream(fileName, FileMode.OpenOrCreate ))
{
Document pdfDoc = new Document(PageSize.A4, 20, 20, 20, 20);
PdfWriter.GetInstance(pdfDoc, stream);
pdfDoc.Open();
pdfDoc.Add(pdfTable);
pdfDoc.Close();
stream.Close();
}
return fileName;
}
private void BuildPDFHeader( PdfPTable pdfTable, String strText)
{
PdfPCell cell = new PdfPCell(new Phrase(strText));
cell.BackgroundColor = new iTextSharp.text.BaseColor(51, 102,102);
pdfTable.AddCell(cell);
}

Introduce the following line right after you define the table:
pdfTable.SplitLate = false;
This will split rows early. In you case, the rows are split only if a row takes up the space of an entire page.

exporting datagrid to pdf in Windows Forms

Im writing a simple app that allows a user to export the created datagrid (here its dataGridView1) to a pdf file with a little help from itextsharp reference.
I've found a useful sample code on the internet but im having some problems in configuring it to export the data that the user enters during his work with the app. The user enters the data in textbox, saves it to the datagrid.
The result pdf file only contains the headers taken from the textbox and no cell content (data entered and saved by users using the textboxes).
Here is the code
//Creating iTextSharp Table from the DataTable data
PdfPTable pdfTable = new PdfPTable(dataGridView1.ColumnCount);
pdfTable.DefaultCell.Padding = 3;
pdfTable.WidthPercentage = 30;
pdfTable.HorizontalAlignment = Element.ALIGN_LEFT;
pdfTable.DefaultCell.BorderWidth = 1;
//Adding Header row
foreach (DataGridViewColumn column in dataGridView1.Columns)
{
PdfPCell cell = new PdfPCell(new Phrase(column.HeaderText));
cell.BackgroundColor = new iTextSharp.text.BaseColor(240, 240, 240);
pdfTable.AddCell(cell);
}
//Exporting to PDF
string folderPath = "C:\\Users\\Marcus\\PDFs\\";
if (!Directory.Exists(folderPath))
{
Directory.CreateDirectory(folderPath);
}
using (FileStream stream = new FileStream(folderPath + "DataGridViewExport.pdf", FileMode.Create))
{
Document pdfDoc = new Document(PageSize.A2, 10f, 10f, 10f, 0f);
PdfWriter.GetInstance(pdfDoc, stream);
pdfDoc.Open();
pdfDoc.Add(pdfTable);
pdfDoc.Close();
stream.Close();
}
}

Okay so this is your header code (which you said works so lets leave that alone)
//Adding Header row
foreach (DataGridViewColumn column in dataGridView1.Columns)
{
PdfPCell cell = new PdfPCell(new Phrase(column.HeaderText));
cell.BackgroundColor = new iTextSharp.text.BaseColor(240, 240, 240);
pdfTable.AddCell(cell);
}
//Lets add code that actually gets the cell contents down below it:
//add the cell contents
foreach(DataGridViewRow row in dataGridView1.Rows) {
foreach(DataGridViewCell cell in row.Cells) {
//we need to call .Value to get the value of the cell, but since a Phrase takes in
//a String, we need to convert the .Value to a String using .ToString()
PdfPCell pdfCell = new PdfPCell(new Phrase(cell.Value.ToString())); //this .Value property is that of a DataGridViewCell
pdfTable.AddCell(pdfCell);
}
}
DataGridViewCell should have a Value property. Use that to get your value of the cells.

private static Phrase FormatPageHeaderPhrase(string value)
{
return new Phrase(value, FontFactory.GetFont(FontFactory.TIMES, 10, Font.BOLD, new BaseColor(255, 0, 0)));
}
Screenshoot of PDF:

Try the below links:
Creating PDFs with iTextSharp
Code sample for using iTextSharp PDF library, by Massoud Mazar

There are different ways to solve this.
One of them, is by using page events. You create a page event implementing the OnEndPage() method. If writer.PageNumber > 1, you add a header, for instance like this:
ColumnText.ShowTextAligned(writer.DirectContent,
Element.ALIGN_RIGHT, "Continued from previous page", 36, 820, 0);
See the examples from chapter 5 for more info about page events.
Another way to solve this, is by introducing a table header: table.HeaderRows = 1; so that the first row is repeated (make sure that row contains a cell that spans all columns saying "Continued from previous page"). To avoid that this header appears on the first page, use table.SkipFirstHeader = true;
