Short Description

GS1-128 (EAN-128) was developed to provide a worldwide format and standard for exchanging common data between companies.

While other bar codes simply encode data with no respect for what the data represents, GS1-128 encodes data and encodes what that data represents.

Bar Code Properties

The type of a bar code control’s Symbology property is EAN128Generator.

The following properties are specific to the GS1-128 (EAN-128) type.

• Code128Generator.CharacterSet

  Gets or sets the character set type for the bar code.

• EAN128Generator.FNC1Substitute

  Gets or sets 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.

• EAN128Generator.HumanReadableText

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

Examples

The following code creates a GS1-128 - EAN-128 (UCC) bar code and specifies its main properties.

Public Function CreateGS1128BarCode(ByVal BarCodeText As String) As XRBarCode
    ' Create a bar code control.
    Dim barCode As New XRBarCode()

    ' Set the bar code's type to EAN 128.
    barCode.Symbology = New EAN128Generator()

    ' Adjust the properties specific to the bar code type.
    CType(barCode.Symbology, EAN128Generator).CharacterSet = Code128Charset.CharsetB

    Return barCode
End Function

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

C#

using System.Drawing.Printing;

private void XtraReport1_BeforePrint(object sender, PrintEventArgs e) {
    this.Detail.Controls.Add(CreateGS1128BarCode("012345678"));
}

VB.NET

Imports System.Drawing.Printing

Private Sub XtraReport1_BeforePrint(ByVal sender As Object, ByVal e As PrintEventArgs)
    Me.Detail.Controls.Add(CreateGS1128BarCode("012345678"))
