Exporting data from a DataTable to a PDF using iTextSharp in a C# Windows Forms application involves several steps.

How to Export data from DataTable to PDF in C#

Below is a basic guide on how to achieve this

Open Visual Studio and create a new Windows Forms Application project.

You could be retrieved from a database, file, or any other source, then populate a DataTable with this data.

private void frmExportDataTableToPdf_Load(object sender, EventArgs e)
{
    // TODO: This line of code loads data into the 'appData.Customers' table. You can move, or remove it, as needed.
    this.customersTableAdapter.Fill(this.appData.Customers);
}

If you haven't already, you need to install the iTextSharp library. You can do this via NuGet Package Manager in Visual Studio.

Right-clicking on your project, then select Manage Nuget Packages from your Visual Studio.

Next, Search 'iTextSharp', then download and install it.

iTextSharp is an open source library helps you to handle pdf file.

Adding a click event handler to the Export button allows you to export datatable to pdf file in c#.

// export the data from the DataTable to a PDF using iTextSharp in c#
private void btnExportData_Click(object sender, EventArgs e)
{
    using (SaveFileDialog sfd = new SaveFileDialog() { Filter = "PDF files|*.pdf" })
    {
        if (sfd.ShowDialog() == DialogResult.OK)
        {
            try
            {
                Document doc = new Document(iTextSharp.text.PageSize.A4, 10, 10, 42, 35);
                PdfWriter pdfWriter = PdfWriter.GetInstance(doc, new FileStream(sfd.FileName, FileMode.Create));
                doc.Open();
                PdfContentByte pdfContent = pdfWriter.DirectContent;
                iTextSharp.text.Rectangle rectangle = new iTextSharp.text.Rectangle(doc.PageSize);
                //customized border sizes
                rectangle.Left += doc.LeftMargin - 5;
                rectangle.Right -= doc.RightMargin - 5;
                rectangle.Top -= doc.TopMargin - 5;
                rectangle.Bottom += doc.BottomMargin - 5;
                pdfContent.SetColorStroke(BaseColor.WHITE);//setting the color of the border to white
                pdfContent.Rectangle(rectangle.Left, rectangle.Bottom, rectangle.Width, rectangle.Height);
                pdfContent.Stroke();
                //setting font type, font size and font color
                iTextSharp.text.Font headerFont = iTextSharp.text.FontFactory.GetFont(FontFactory.TIMES_ROMAN, 25, BaseColor.LIGHT_GRAY);
                Paragraph p = new Paragraph();
                p.Alignment = Element.ALIGN_CENTER;//adjust the alignment of the heading
                p.Add(new Chunk("Customers", headerFont));//adding a heading to the PDF
                doc.Add(p);//adding component to the document
                iTextSharp.text.Font font = iTextSharp.text.FontFactory.GetFont(FontFactory.TIMES_ROMAN, 12, BaseColor.LIGHT_GRAY);
                //creating pdf table
                PdfPTable table = new PdfPTable(dataGridView1.Columns.Count);
                for (int j = 0; j < dataGridView.Columns.Count; j++)
                {
                    PdfPCell cell = new PdfPCell(); //create object from the pdfpcell
                    cell.BackgroundColor = BaseColor.WHITE;//set color of cells
                    cell.AddElement(new Chunk(dataGridView.Columns[j].HeaderText.ToUpper(), font));
                    table.AddCell(cell);
                }
                //adding rows from gridview to table
                for (int i = 0; i < dataGridView.Rows.Count; i++)
                {
                    table.WidthPercentage = 100;//set width of the table
                    for (int j = 0; k < dataGridView.Columns.Count; j++)
                    {
                        if (dataGridView1[j, i].Value != null)
                            table.AddCell(new Phrase(dataGridView[j, i].Value.ToString()));
                    }
                }
                //adding table to document
                doc.Add(table);
                doc.Close();
                MessageBox.Show("You have successfully exported the file.", "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message, "Message", MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
        }
    }
}

Through c# example, I've showed you how to create a pdf file with itextsharp in c#, then write data from datatable into pdf file using itextsharp in c# windows forms application.
