- Install the Syncfusion.Pdf.WinForms NuGet package as a reference to your .NET Framework application from NuGet.org.
- Include the following namespace in the Program.cs file.
C#
using System.Drawing; using Syncfusion.Pdf; using Syncfusion.Pdf.Grid; using Syncfusion.Pdf.Barcode;
VB.NET
Imports System.Drawing Imports Syncfusion.Pdf Imports Syncfusion.Pdf.Grid Imports Syncfusion.Pdf.Barcode
- Use the following code snippet to draw a barcode in a PDF table cell.
C#
//Create a new PDF document
PdfDocument pdfDocument = new PdfDocument();
//Add a page
PdfPage page = pdfDocument.Pages.Add();
//Create a new PdfGrid
PdfGrid pdfGrid = new PdfGrid();
//Create a DataTable
DataTable dataTable = new DataTable();
//Add columns to the DataTable
dataTable.Columns.Add("Barcode Text");
dataTable.Columns.Add("Barcode");
//Add rows to the DataTable
dataTable.Rows.Add(new object[] { "CODE39$", "" });
//Assign data source
pdfGrid.DataSource = dataTable;
//Set height
pdfGrid.Rows[0].Height = 70;
pdfGrid.BeginCellLayout += PdfGrid_BeginCellLayout;
//Draw grid to the page of PDF document
pdfGrid.Draw(page, new PointF(10, 10));
//Save the document
pdfDocument.Save("Output.pdf");
//Close the document
pdfDocument.Close(true);
//This will open the PDF file so, the result will be seen in the default PDF viewer
Process.Start("Output.pdf");
/// <summary>
/// Event handler to draw barcode in grid cell
/// </summary>
/// <param name="sender"></param>
/// <param name="args"></param>
private static void PdfGrid_BeginCellLayout(object sender, PdfGridBeginCellLayoutEventArgs args)
{
if(args.RowIndex==0 && args.CellIndex==1 && !args.IsHeaderRow)
{
//Drawing Code39 barcode
PdfCode39Barcode barcode = new PdfCode39Barcode();
//Setting height of the barcode
barcode.BarHeight = 45;
barcode.Text = "CODE39$";
//Draw barcode with respect to the grid cell bounds
barcode.Draw(page, new PointF(args.Bounds.X+5, args.Bounds.Y+5));
}
}
