• 3 minutes to read

GS1 QR Code is a variant of the QR Code symbology that conforms to GS1 General Specification.

Add a Bar Code to a Report

1. Drag the XRBarCode item from the DX.23.1: Report Controls tab and drop it onto the report.

   

2. Set the XRBarCode control’s Symbology property to QRCodeGS1 (an object of the QRCodeGS1Generator type).

   

3. Specify common barcode properties and properties specific to GS1 QR Code.

Specific Properties

AutoModule

Gets or sets whether the Module property value should be calculated automatically based on the barcode size.

CompactionMode

Gets or sets whether numeric, alphanumeric or byte mode should be used to encode the barcode’s data.

ErrorCorrectionLevel

Gets or sets the amount of redundancy built into the bar code’s coding, to compensate for calculation errors.

Version

Gets or sets the bar code’s size.

Logo

Specifies the image that overlays the QR code.

FNC1Substitute

Specifies the symbol (or set of symbols) in the bar code’s text that will be replaced with the FNC1 functional character when the bar code’s bars are drawn.

Runtime Example

The following code creates a GS1 QR Code barcode and specifies its properties:

C#

using System;
using System.Collections.Generic;
using System.Drawing.Printing;
using System.Windows.Forms;
using DevExpress.XtraPrinting.BarCode;
using DevExpress.XtraReports.UI;
// ...
public XRBarCode CreateQRCodeGS1BarCode(string BarCodeText) {
    // Create a barcode control.
    XRBarCode barCode = new XRBarCode();

    // Set the barcode's type to QRCode.
    barCode.Symbology = new QRCodeGS1Generator();

    // Adjust the barcode's main properties.
    barCode.Text = BarCodeText;
    barCode.Width = 400;
    barCode.Height = 150;

    // If the AutoModule property is set to false, uncomment the next line.
    barCode.AutoModule = true;
    // barcode.Module = 3;

    // Adjust the properties specific to the barcode type.
    ((QRCodeGS1Generator)barCode.Symbology).CompactionMode = QRCodeCompactionMode.AlphaNumeric;
    ((QRCodeGS1Generator)barCode.Symbology).FNC1Substitute = "#";
    ((QRCodeGS1Generator)barCode.Symbology).ErrorCorrectionLevel = QRCodeErrorCorrectionLevel.H;
    ((QRCodeGS1Generator)barCode.Symbology).Version = QRCodeVersion.AutoVersion;

    return barCode;
}

VB.NET

Imports System
Imports System.Collections.Generic
Imports System.Drawing.Printing
Imports System.Windows.Forms
Imports DevExpress.XtraPrinting.BarCode
Imports DevExpress.XtraReports.UI
' ...
Public Function CreateQRCodeGS1BarCode(ByVal BarCodeText As String) As XRBarCode
    ' Create a barcode control.
    Dim barCode As New XRBarCode()

    ' Set the barcode's type to QRCode.
    barCode.Symbology = New QRCodeGS1Generator()

    ' Adjust the barcode's main properties.
    barCode.Text = BarCodeText
    barCode.Width = 400
    barCode.Height = 150

    ' If the AutoModule property is set to false, uncomment the next line.
    barCode.AutoModule = True
    ' barcode.Module = 3;

    ' Adjust the properties specific to the barcode type.
    CType(barCode.Symbology, QRCodeGS1Generator).CompactionMode = QRCodeCompactionMode.AlphaNumeric
    CType(barCode.Symbology, QRCodeGS1Generator).FNC1Substitute = "#"
    CType(barCode.Symbology, QRCodeGS1Generator).ErrorCorrectionLevel = QRCodeErrorCorrectionLevel.H
    CType(barCode.Symbology, QRCodeGS1Generator).Version = QRCodeVersion.AutoVersion

    Return barCode
End Function

The code example below shows how to create a report with a GS1 QR Code barcode:

C#

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

var barCode = CreateQRCodeGS1BarCode("0123456789");

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

VB.NET

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

Private barCode = CreateQRCodeGS1BarCode("0123456789")

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