  • SegmentsInRow

Runtime Example

The following code creates the GS1 DataBar barcode and specifies its properties.


The complete sample project is available in the following repository:

using System;
using System.Collections.Generic;
using System.Drawing.Printing;
using System.Windows.Forms;
using DevExpress.XtraPrinting.BarCode;
using DevExpress.XtraReports.UI;
// ...
public XRBarCode CreateDataBarGS1BarCode(string BarCodeText) {
    // Create a bar code control.
    XRBarCode barCode = new XRBarCode();

    // Set the bar code's type to GS1 DataBar.
    barCode.Symbology = new DataBarGenerator();

    // Adjust the bar code's main properties.
    barCode.Text = BarCodeText;
    barCode.Width = 250;
    barCode.Height = 160;

    // Adjust the properties specific to the bar code type.
    ((DataBarGenerator)barCode.Symbology).FNC1Substitute = "#";
    ((DataBarGenerator)barCode.Symbology).SegmentsInRow = 4;
    ((DataBarGenerator)barCode.Symbology).Type = DataBarType.ExpandedStacked;

    return barCode;

To add the XRBarCode to a report band, handle the report’s BeforePrint event.

using System.Drawing.Printing;
// ...

private void XtraReport1_BeforePrint(object sender, PrintEventArgs e) {
