EAN-8 is a shorter version of the EAN-13. EAN-8 can encode 8 digits, the first 7 of which users should specify, and the last digit (check digit) is generated automatically. EAN-8 is used on small packages where EAN-13 does not fit, for example on pencils or chewing gum packets.

Refer to the following article for more details: EAN-8.

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 EAN8 (an object of the EAN8Generator type).

   

3. Specify common barcode properties.

Runtime Example

The following code creates the EAN 8 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 CreateEAN8BarCode(string BarCodeText) {
    // Create a bar code control.
    XRBarCode barCode = new XRBarCode();

    // Set the bar code's type to EAN 8.
    barCode.Symbology = new EAN8Generator();

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

    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 CreateEAN8BarCode(ByVal BarCodeText As String) As XRBarCode
    ' Create a bar code control.
    Dim barCode As New XRBarCode()

    ' Set the bar code's type to EAN 8.
    barCode.Symbology = New EAN8Generator()

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

    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(CreateEAN8BarCode("0123456"));
}

VB.NET

Imports System.Drawing.Printing
' ...

Private Sub XtraReport1_BeforePrint(ByVal sender As Object, ByVal e As PrintEventArgs)
    Me.Detail.Controls.Add(CreateEAN8BarCode("0123456"))
End Sub
