Code 128 is a high-density symbology that encodes alphanumeric data.

Add the Bar Code to a Report

1. Drag the XRBarCode item from the DX.20.2: Report Controls tab and drop it onto the report.

   

2. Set the XRBarCode control’s Symbology property to Code128 (an object of the Code128Generator type).

   

3. Specify common barcode properties and properties specific to Code128.

Specific Properties

Use the barcode’s CharacterSet property to specify a character set for this barcode.

Runtime Example

The following code creates the Code 128 barcode and specifies its properties.

Note

The complete sample project is available in the following repository: https://github.com/DevExpress-Examples/Reporting_how-to-add-a-bar-code-to-a-report-e167.

Form1.cs

using System;
using System.Collections.Generic;
using System.Drawing.Printing;
using System.Windows.Forms;
using DevExpress.XtraPrinting.BarCode;
using DevExpress.XtraReports.UI;
// ...
public XRBarCode CreateCode128BarCode(string BarCodeText) {
    // Create a bar code control.
    XRBarCode barCode = new XRBarCode();

    // Set the bar code's type to Code 128.
    barCode.Symbology = new Code128Generator();

    // Adjust the bar code's main properties.
    barCode.Text = BarCodeText;
    barCode.Width = 400;
    barCode.Height = 100;

    // Adjust the properties specific to the bar code type.
    ((Code128Generator)barCode.Symbology).CharacterSet = Code128Charset.CharsetB;

    return barCode;
}

Form1.vb

Imports System
Imports System.Collections.Generic
Imports System.Drawing.Printing
Imports System.Windows.Forms
Imports DevExpress.XtraPrinting.BarCode
Imports DevExpress.XtraReports.UI
' ...
Public Function CreateCode128BarCode(ByVal BarCodeText As String) As XRBarCode
    ' Create a bar code control.
    Dim barCode As New XRBarCode()

    ' Set the bar code's type to Code 128.
    barCode.Symbology = New Code128Generator()

    ' Adjust the bar code's main properties.
    barCode.Text = BarCodeText
    barCode.Width = 400
    barCode.Height = 100

    ' Adjust the properties specific to the bar code type.
    CType(barCode.Symbology, Code128Generator).CharacterSet = Code128Charset.CharsetB

    Return barCode
End Function

To add the XRBarCode to a report band, handle the report’s BeforePrint event.

C#

using System.Drawing.Printing;
// ...

private void XtraReport1_BeforePrint(object sender, PrintEventArgs e) {
    this.Detail.Controls.Add(CreateCode128BarCode("012345678"));
}

VB.NET

Imports System.Drawing.Printing
' ...

Private Sub XtraReport1_BeforePrint(ByVal sender As Object, ByVal e As PrintEventArgs)
    Me.Detail.Controls.Add(CreateCode128BarCode("012345678"))
End Sub
