.NET RDLC Reports EAN-13 Barcode Generator

The EAN-13 barcode generator for RDLC client reports is an easy to use .NET control based on Visual Studio, designed for use in both Windows RDLC and ASP.NET RDLC environments. It enables generation of high quality barcode images in RDLC local reports using C# or VB.NET class libraries.

BarcodeLib provides step by step tutorials for printing barcodes in RDLC reports using C# in ASP.NET and Windows Forms applications.

• How to print barcodes in RDLC reports in ASP.NET web form applications
• How to print barcodes in RDLC reports in Windows Forms applications

In the above tutorials, Code 128 barcodes are created and printed in RDLC reports. The following instructions update the C# demonstration code to print EAN-13 barcodes in RDLC reports.

• Open the C# class file Form1.cs in the tutorial project using Visual Studio 2022.
• Change the linear barcode format to BarcodeType.EAN13.

To create and print an EAN-13 barcode with a 2 digit add on in an RDLC report, follow the instructions below.

• Open the C# class file Form1.cs in the tutorial project using Visual Studio 2022.
• Change the barcode format property Type to BarcodeType.EAN13_2.
• Set the add on data value (a 2 digit string) in the SupData property.

To print an EAN-13 barcode with a 5 digit add on in an RDLC report, follow steps similar to those for the 2 digit add on.

• Open the C# class file Form1.cs in the tutorial project using Visual Studio 2022.
• Change the barcode format property Type to BarcodeType.EAN13_5.
• Set the add on data value (a 5 digit string) in the SupData property.

The GS1 standard recommends printing EAN-13 text using the OCR B font. If the OCR B font is installed on the system, the following C# code can be used to apply the EAN-13 text font style in an RDLC report.

• Open the C# class file Form1.cs using Visual Studio 2022.
• Set the new font style in the TextFont property.

EAN-13 barcodes may include a quiet zone indicator at the end of the barcode text label. By default, the RDLC EAN-13 Barcode Generator library prints this indicator. It can be hidden in the RDLC report.

• Open the C# class file Form1.cs using Visual Studio 2022.
• Set the ShowQuietZoneIndicator property to false to hide the EAN-13 quiet zone indicator.

The spacing around the first and last digits of the EAN-13 barcode can be adjusted.

• Open the C# class file Form1.cs using Visual Studio 2022.
• Use the following properties:
  • UPCEANLeadDigitSpace: The space between the first digit and the start character bar. Default value is 0.
  • UPCEANTrailDigitSpace: The space between the stop character bar and the quiet zone indicator. Default value is 0.

The core workflow for generating EAN-13 barcodes in an RDLC Local Report is as follows:

• Initialize a Linear barcode object with the barcode type set to EAN13, EAN13_2, or EAN13_5 as required.
• Configure the barcode data (and add on data if applicable) for the RDLC report.
• Optionally customize the text label font, quiet zone indicator visibility, and digit spacing.
• Generate the barcode byte stream.
• Bind the byte stream to an RDLC Image report item.
• Render the report through the ReportViewer Control (ASP.NET / Windows Forms).

Key configurations for RDLC report include:

• Selection of the appropriate barcode type (standard EAN-13 or with 2 digit / 5 digit add on).
• Use of OCR B font for the text label as recommended by GS1 standards.
• Proper spacing for lead and trail digits to maintain scannability.

These settings must align with the properties of the RDLC Image report item to ensure accurate rendering. The same integration patterns apply when using Crystal Reports for .NET, where image items in report templates can similarly bind to dynamically generated EAN-13 barcode images, and dimension and font specifications must match the report layout requirements.
