GS1 Data Matrix is a variant of the Data Matrix symbology that conforms to GS1 specifications.

Refer to the GS1 General Specification for more details.

Add the Bar Code to a Report

1. Drag the XRBarCode item from the DX.24.2: Report Controls tab and drop it onto the report.

   

2. Set the XRBarCode control’s Symbology property to DataMatrixGS1 (an object of the DataMatrixGS1Generator type).

   

3. Specify common barcode properties and properties specific to GS1 Data Matrix.

Specific Properties

• AutoModule

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

• 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.

• HumanReadableText

  Specifies whether or not parentheses should be included in the bar code’s text.

Runtime Example

The following code creates the GS1- Data Matrix barcode and specifies its properties.

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

    return barCode;

    CType(barCode.Symbology, DataMatrixGS1Generator).HumanReadableText = True

    Return barCode
End Function

The code example below shows how to create a report with the GS1- Data Matrix barcode:

C#

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

var barCode = CreateDataMatrixGS1BarCode("012345678");

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

VB.NET

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

Private barCode = CreateDataMatrixGS1BarCode("012345678")

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