The code example below shows how to create a report with the GS1 DataBar barcode:

C#

using DevExpress.XtraPrinting.BarCode;
using DevExpress.XtraReports.UI;
//...

var barCode = CreateDataBarGS1BarCode("012345678");

var report = new XtraReport() {
    Bands = {
        new DetailBand() {
            Controls = { barCode }
        }
    }
};

VB.NET

Imports DevExpress.XtraPrinting.BarCode
Imports DevExpress.XtraReports.UI
'...

Private barCode = CreateDataBarGS1BarCode("012345678")

Dim report As New XtraReport()
Dim band = New DetailBand()
band.Controls.Add(barCode)
