A Quick Response (QR) Code is a two-dimensional code. QR scanners, mobile phones with a camera, and smartphones can read this code.

Refer to the following article for more information: QR Code.

Available Characters

A QR Code can encode numeric, alphanumeric, and binary data. The table below shows the available characters for each mode:

Mode	Available Characters
Numeric	0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Alphanumeric	0–9, A–Z (upper-case only), space, $, %, *, +, -, ., /, :
Byte/Binary	ISO 8859-1

Use the barcode’s CompactionMode property to specify a data encoding mode: Numeric, AlphaNumeric, or Byte. Choose a mode that suits your data.

Add the Barcode to a Report

Drag the XRBarCode item from the DX.25.2: Report Controls tab and drop it onto the report.
Set the XRBarCode control’s Symbology property to QRCode (an object of the QRCodeGenerator type).
Specify common barcode properties and properties specific to the QR Code.

Specific Properties

XRBarCode.AutoModuleGets or sets whether the Module property value should be calculated automatically based on the barcode size.BarCodeControl.AutoModuleGets or sets a value that specifies whether the BarCodeControl.Module property value should be calculated automatically based upon the bar code’s size.QRCodeGenerator.CompactionModeGets or sets whether numeric, alphanumeric or byte mode should be used to encode the barcode’s data.QRCodeGenerator.ErrorCorrectionLevelGets or sets the amount of redundancy built into the bar code’s coding, to compensate for calculation errors.QRCodeGenerator.VersionGets or sets the barcode’s version.QRCodeGenerator.IncludeQuietZoneGets or sets whether to add a blank space around the QR code.QRCodeGenerator.LogoSpecifies the image that overlays the QR code.QRCodeGenerator.FrameOptionsGets or sets the frame for QR codes.

Runtime Example

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

using System.Windows.Forms;
using DevExpress.XtraPrinting.BarCode;

End Function

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

C#
VB.NET

csharp

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

var barCode = CreateQRCodeBarCode("012345678");

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

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

Private barCode = CreateQRCodeBarCode("012345678")

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