Display Data in DataGridView by using the below code sinppet: -

private void Form1_Load(object sender, EventArgs e)
{
    // Fetch and bind your data to the DataGridView
    DataTable data = GetDataFromDatabase(); // Replace with your actual data retrieval logic
    dataGridView1.DataSource = data;
}

Install a PDF library like iTextSharp to handle the PDF export. You can install it using NuGet Package Manager:

Install-Package itext7

Handle the button click event to export data to PDF when the button is clicked.

using iText.Kernel.Pdf;
using iText.Layout;
using iText.Layout.Element;

private void btnPdfExport_Click(object sender, EventArgs e)
{
    ExportDataToPdf();
}

private void ExportDataToPdf()
{
    try
    {
        // Create a new PDF document
        using (PdfWriter writer = new PdfWriter("output.pdf"))
        {
            using (PdfDocument pdf = new PdfDocument(writer))
            {
                Document document = new Document(pdf);
                
                // Add a table to the document
                iText.Layout.Element.Table table = new iText.Layout.Element.Table(dataGridView1.ColumnCount);

                // Add header row
                foreach (DataGridViewColumn column in dataGridView1.Columns)
                {
                    table.AddCell(new Cell().Add(new Paragraph(column.HeaderText)));
                }

                // Add data rows
                foreach (DataGridViewRow row in dataGridView1.Rows)
                {
                    foreach (DataGridViewCell cell in row.Cells)
                    {
                        table.AddCell(new Cell().Add(new Paragraph(cell.Value.ToString())));
                    }
                }

                // Add the table to the document
                document.Add(table);
            }
        }

        MessageBox.Show("Data exported to PDF successfully.");
    }
    catch (Exception ex)
    {
        MessageBox.Show($"Error exporting data to PDF: {ex.Message}");
    }
}
