Add the Bar Code to a Report

1. Drag the XRBarCode item from the DX.20.2: Report Controls tab and drop it onto the report.

   

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

   

3. Specify common barcode properties and properties specific to Codabar.

Specific Properties

• StartSymbol

  Gets or sets the first (start) symbol used to code the barcode’s structure.

• StopSymbol

  Gets or sets the last (stop) symbol used to code the barcode’s structure.

• WideNarrowRatio

  Gets or sets the density of a barcode’s bars.

Runtime Example

The following code creates the Codabar barcode and specifies its properties:

Note

The complete sample project is available in the following repository: https://github.com/DevExpress-Examples/Reporting_how-to-add-a-bar-code-to-a-report-e167.

Form1.cs

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

    // Set the bar code's type to Codabar
    barCode.Symbology = new CodabarGenerator();

    // Adjust the bar code's main properties.
    barCode.Text = BarCodeText;
    barCode.Width = 300;
    barCode.Height = 100;

    // Adjust the properties specific to the bar code type.
    ((CodabarGenerator)barCode.Symbology).StartSymbol = CodabarStartStopSymbol.C;
    ((CodabarGenerator)barCode.Symbology).StopSymbol = CodabarStartStopSymbol.D;
    ((CodabarGenerator)barCode.Symbology).WideNarrowRatio = 2.5F;

    return barCode;
}

Form1.vb

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

    ' Set the bar code's type to Codabar
    barCode.Symbology = New CodabarGenerator()

    ' Adjust the bar code's main properties.
    barCode.Text = BarCodeText
    barCode.Width = 300
    barCode.Height = 100

    ' Adjust the properties specific to the bar code type.
    CType(barCode.Symbology, CodabarGenerator).StartSymbol = CodabarStartStopSymbol.C
    CType(barCode.Symbology, CodabarGenerator).StopSymbol = CodabarStartStopSymbol.D
    CType(barCode.Symbology, CodabarGenerator).WideNarrowRatio = 2.5F

    Return barCode
End Function

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

C#

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

private void XtraReport1_BeforePrint(object sender, PrintEventArgs e) {
    this.Detail.Controls.Add(CreateCodabarBarCode("0123456789"));
}

VB.NET

Imports System.Drawing.Printing
' ...

Private Sub XtraReport1_BeforePrint(ByVal sender As Object, ByVal e As PrintEventArgs)
    Me.Detail.Controls.Add(CreateCodabarBarCode("0123456789"))
End Sub
