.NET Crystal Reports QR Code Barcode Introduction

How to Generate QR Code barcode in Crystal Reports with ASP.NET Website

1. Create a new ASP.NET website.
• Create a new web site project using "ASP.NET Crystal Reports Web Site" as template, named "BarcodeforCrystalReportsWebSite".
2. Add a Crystal Report item to the project.
• Add a new item (Crystal Report), named "CustomerReport.rpt" to the project. view image
• Select Expert as "Mail Label". Click "OK" button. view image
• In "Mailing Labels Report Creation Wizard", click "Create New Connection", and expand "ADO.NET". view image
• In "ADO.NET" form, select "CustomerDataSet.xsd" file in your downloaded package, and click "Finish" button. view image
• In "Mailing Labels Report Creation Wizard", add table "Customer" under "ADO.NET", to selected table. And click "Next" button. view image
• Add all three fields "ID", "CustomerId", "CustomerName", to "Fields to Display:". Click "Next". view image
• Select default label "Return Address (Avery 5267)", and click "Finish" button.
• Now you can view the report template, and find that field "Barcode" not in the report template. view image
• Re-arrange the report template. view image
• Drag field "Barcode" to the report template. Right click "Barcode" object and select "Format Object" menu. view image
• In "Format Editor" form, check "Can Grow" property. view image
3. Add Crystal Report Viewer to the Default.aspx.

     using System.Data.OleDb;
     using System.Drawing.Imaging;
     using BarcodeLib.Barcode.CrystalReports;
     using BarcodeLib.Barcode;


     protected void Page_Load(object sender, EventArgs e)
     {
     // Create the database connection. Please change to correct data file (BarcodeDemoData.mdb) path.
     OleDbConnection aConnection = new OleDbConnection(
        "Provider=Microsoft.Jet.OLEDB.4.0;
        Data Source=C:/BarcodeLib_NETBarcode_Trial/ReportingData/BarcodeDemoData.mdb");
     aConnection.Open();
	
     OleDbDataAdapter dataAdapter = new OleDbDataAdapter("SELECT * FROM Customer", aConnection);
     DataSet ds = new DataSet();
     dataAdapter.Fill(ds);
	
     // Add the Barcode column to the DataSet
     ds.Tables[0].Columns.Add(new DataColumn("Barcode", typeof(byte[])));
	
     // Use QRCodeCrystal for QR Code
     QRCodeCrystal barcode = new QRCodeCrystal();
    
     // Barcode settings
     barcode.ModuleSize = 3; 
     barcode.ImageFormat = System.Drawing.Imaging.ImageFormat.Png;
	
     foreach (DataRow dr in ds.Tables[0].Rows)
     {
        barcode.Data = (int)dr["CustomerId"] + "";
        byte[] imageData = barcode.drawBarcodeAsBytes();
        dr["Barcode"] = imageData;
     }
	
     CrystalReportSource1.ReportDocument.Load(Server.MapPath("CustomerReport.rpt"));
     CrystalReportSource1.ReportDocument.SetDataSource(ds.Tables[0]);
     CrystalReportSource1.DataBind();

     }

How to Create QR Code Bar Code in Crystal Reports with .NET Windows Forms

1. Create a new Windows Application Project.
• Create a new project using "Crystal Reports Application" as template, named "BarcodeforCrystalReports".
2. Add a Crystal Report item to the project. View How to Add Crystal Report to Project
3. Add Crystal Report Viewer to the window form.
• Resize "Form1", and add "CrystalReportViewer" to the form, with the default setting unchanged. view image
• Add a reference to BarcodeLib.Barcode.CrystalReports.dll.
• Add the following code to the Form1.cs file.

     using System.Data.OleDb;
     using System.Drawing.Imaging;
     using BarcodeLib.Barcode.CrystalReports;
     using BarcodeLib.Barcode;


     private void Form1_Load(object sender, EventArgs e)
     {
     // Create the database connection. Please change to correct data file (BarcodeDemoData.mdb) path.
     OleDbConnection aConnection = new OleDbConnection(
        "Provider=Microsoft.Jet.OLEDB.4.0;
        Data Source=C:/BarcodeLib_NETBarcode_Trial/ReportingData/BarcodeDemoData.mdb");aConnection.Open();

     OleDbDataAdapter dataAdapter = new OleDbDataAdapter("SELECT * FROM Customer", aConnection);
     DataSet ds = new DataSet();
     dataAdapter.Fill(ds);

     // Add the Barcode column to the DataSet
     ds.Tables[0].Columns.Add(new DataColumn("Barcode", typeof(byte[])));

     // Use QRCodeCrystal for QR Code
     QRCodeCrystal barcode = new QRCodeCrystal();

     // Barcode settings
     barcode.ModuleSize = 3; 
     barcode.ImageFormat = System.Drawing.Imaging.ImageFormat.Png;

     foreach (DataRow dr in ds.Tables[0].Rows)
     {
        barcode.Data = (int)dr["CustomerId"] + "";
        byte[] imageData = barcode.drawBarcodeAsBytes();
        dr["Barcode"] = imageData;
     }

     CustomerReport rpt = new CustomerReport();
     rpt.SetDataSource(ds);

     this.crystalReportViewer1.ReportSource = rpt;

     //close the connection Its important.
     aConnection.Close();

Print QR Code with Diverse Text Formats in Crystal Reports

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.

Encode Unicode Text (Multilingual Reports)

QR Codes do not natively support Unicode, but two methods enable multilingual Crystal Reports:

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

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 FNC1 = FNC1.FNC1_1ST_POS to enable GS1 formatting.
• In the Data property, include AI codes in parentheses followed by the data.

Customizing QR Code Dimensions & Layout for Crystal Reports

Optimize QR Code dimensions for Crystal Reports image controls to avoid distortion in printed or exported reports. Use BarcodeWidth; QR Codes are square, so the width 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 BarcodeWidth).
• Use UOM to select the preferred unit of measure (inch or cm).
• Specify the QR Code rendering side with BarcodeWidth.

Configure QR Code Quiet Zones

Customizing QR Code Appearance for Crystal Reports

Configure Colors

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

• ForeColor: QR Code modules color, typically black.
• BackColor: QR Code background color, typically white.

Advanced Image Options

Advanced QR Code Options for ASP.NET/WinForms Crystal Reports

Error Correction Mode

QR Code Version

Structured Append Mode

Split a large text message across up to 16 QR Codes, which is useful when the data exceeds the capacity of a single QR Code.

FNC1 First Position (GS1)

Enable FNC1.FNC1_1ST_POS for GS1-compliant Crystal Reports in supply chain and retail scenarios.
