The QR Code barcode generation control for Crystal Reports is a professional and robust .NET component designed for integration with Visual Studio 2005, 2008, 2010, and later versions. It enables dynamic generation of QR Code symbols within Crystal Reports, suitable for listing and reporting scenarios.

This guide delivers a structured, step-by-step approach to creating and printing QR Code (Quick Response Code) images into Crystal Reports for .NET, supporting both ASP.NET and Windows Forms projects.

Using the Barcode Generator for Crystal Reports .NET library, you can embed QR Codes directly into .rpt files (Crystal Reports template files) for display in CrystalReportViewer (WinForms, WPF, or ASP.NET viewer control) or exported report formats.

Compatibility: Barcode for Crystal Reports control / dll is compatible with ISO/IEC 18004 bar code symbology specification.

BarcodeLib.com provides detailed guides for users to create barcodes in Crystal Report in C# ASP.NET web and WinForms desktop application.

• How to Print Barcodes in Crystal Reports in C# ASP.NET web form application?
• How to Print Barcodes in Crystal Reports in C# WinForms application?

The demo ASP.NET and WinForms application will create and print Code 128 barcodes in the report. To generate QR Code in the report, you need do the following code modification.

1. • For ASP.NET web application, open file Default.aspx.cs in Visual Studio, go to method Page_Load
   • For WinForms application, open file Form1.cs in Visual Studio, go to method Form1_Load
2. Change the default Code 128 barcode generation code to the following QR Code generation C# code.
   

   QRCodeCrystal barcode = new QRCodeCrystal();
   barcode.UOM = UnitOfMeasure.INCH;
   barcode.ImageWidth = 2;
   barcode.ImageHeight = 2;
   barcode.ResizeImagePaddingTransparent = false;
   barcode.ImageFormat = BLImageFormat.PNG;
   

3. Change QR Code image size to 2-inch width and 2-inch height.
   Open report file CrystalReport1.rpt in Visual Studio. Click the Barcode item, change the properties:
   Property XScaling value to 2.
   Property YScaling value to 2.
   

Now run the modified ASP.NET web application, you can view the QR Codes printed in the report in browser.

Encode ASCII Non-Printing Characters

ASCII control characters, such as carriage return (CR), require special encoding for structured data in Crystal Reports formula field output.

• Set ProcessTilde to true to enable the tilde (~) as an escape character.
• In the Data property, non-printable characters are converted to the ~ddd format, where ddd is the three-digit ASCII value.

The following C# codes will print QR Code with SEVEN characters encoded. And the ASCII char carriage return integer value is 13.

QRCode barcode = new QRCode();
barcode.ProcessTilde = true;
barcode.Data = "QR~013Code";

Encode Unicode Text (Multilingual Reports)

QR Codes do not natively support Unicode text encoding, however you can encode Unicode text through binary data encoding in Crystal Reports:

• Set IsUnicodeData to true to print QR Codes with Unicode text encoding in Crystal Reports.
• Enter the Unicode text string in the Data property.

QRCode barcode = new QRCode();
barcode.Data = "Unicode text string here";
barcode.IsUnicodeData = true;

Generate GS1-Compliant QR Codes in Reports

GS1 QR Codes integrate industry-standard data, such as expiration dates and batch numbers, into Crystal Reports for supply chain and retail use cases.

• Set property FNC1Mode with value QRCodeFNC1Mode.FirstPosition to enable GS1 formatting in QR Code.
• In the Data property, include AI codes in parentheses followed by the data.

QRCode barcode = new QRCode();
barcode.Data = "(17)050101(10)ABC123";
barcode.FNC1Mode = QRCodeFNC1Mode.FirstPosition;

Optimize QR Code dimensions for Crystal Reports image controls to avoid distortion in printed or exported reports. QR Codes are square, so the image width (property ImageWidth) defines both dimensions. Add the following C# code to the Crystal Reports for .NET project:

• Determine the QR Code printing size in the .rpt file (matches ImageWidth).
• Use UOM to select the preferred unit of measure (inch or cm).
• Specify the QR Code rendering side with ImageWidth.

barcode.UOM = UnitOfMeasure.INCH;
barcode.ImageWidth = 2;

Configure QR Code Quiet Zones

Quiet zones, or blank space, ensure scannability. Set margins on QR Code images in Crystal Reports.

The QR Code standard requires a quiet zone of 10X, where X is the QR Code module size. Insufficient quiet zones may cause scan errors in printed reports; test physical prints before deployment.

Use the following properties to apply the QR Code left, right, top, bottom margin size.

barcode.LeftMargin = 10;
barcode.RightMargin = 10;
barcode.TopMargin = 10;
barcode.BottomMargin = 10;

Configure Colors

Customize QR Code colors to match brand guidelines, such as Crystal Reports Report Header branding.

• ModuleColor: QR Code modules color, typically black.
• BackgroundColor: QR Code background color, typically white.

barcode.ModuleColor = Color.Red;
barcode.BackgroundColor = Color.LightSeaGreen;

Advanced Image Options

barcode.Resolution = 900;
barcode.BackgroundColor = Color.Transparent;

Error Correction Mode

barcode.ECL = QRCodeErrorCorrectionLevel.M;

QR Code Version

barcode.Version = QRCodeVersion.V2;

Structured Append Mode

FNC1 First Position (GS1)

Set property FNC1Mode with value QRCodeFNC1Mode.FirstPosition to generate GS1 compliant QR Code in Crystal Reports supply chain and retail scenarios.

barcode.FNC1Mode = QRCodeFNC1Mode.FirstPosition;
