How to Generate QR Code in RDLC ReportsHow to Create 2D QR Code Images in RDLC Reports with Free Demo Codes
The KeepAutomation QR Code Barcode Generator for RDLC is a robust, developer-friendly .NET reporting component.
It is purpose-built for seamless QR Code generation and rendering within RDLC local reports across all .NET Framework environments.
This library offers quick, hassle-free integration into existing .NET reporting projects, with no complex setup required.
After embedding the control into RDLC or Crystal Reports, you can easily generate and customize QR Codes via C# or VB.NET code.
All core QR Code parameters are fully configurable, letting you tailor output to match report layout and scanning requirements.
QR Code Barcode Generator for RDLC Reports Overview
QR Code Barcode Generator for RDLC Reports is an advanced QR Code generator developed for generating QR Code in RDLC Reports. The generator is an easy-to-install control library. Once integrated into the report, QR Code could be drawn easily. The parameters of the QR Code are customizable by using C# & VB codes. All QR Code barcode images created with barcode generator dll completely compatible with the latest QR Code barcode encoding specifications.
QR Code Barcode Introduction
The QR Code (Quick Response Code) is a 2-dimensional matrix code. It can encode up to 2509 numeric or 1520 alphanumeric characters and offer three levels of error detection. The smallest QR Code measures 21 X 21 cells (each cell encodes one bit) and can grow in increments of 4 cells to a maximum size of 105 X 105 cells. The squares in the bottom left, top left and top right corners are locator patterns.
How to create & print QR Codes in RDLC Reports (C# .NET: ASP.NET & WinForms)
These guides cover both ASP.NET web applications and .NET Framework Windows Forms desktop projects.
Prior tutorials in this series focus on Code 128 linear barcode generation for RDLC reports.
This guide modifies that existing demo codebase to implement QR Code 2D barcode generation instead.
The same configuration logic can be adapted for Crystal Reports QR Code embedding with minimal .NET code changes.
Guide to Printing QR Codes with Fixed Dimensions in RDLC Reports
Here we will learn how to print, customize QR Code with specified dimension size in RDLC local reports.
We use a .NET Framework Windows Forms project for demonstration, and the same steps apply to ASP.NET.
You can also replicate these settings for Crystal Reports to maintain consistent barcode sizing across reports.
Below is the complete process to generate a QR Code with a 3cm side length in RDLC reports.
Guide to Encoding Text in QR Codes for RDLC Reports
Encoding text data into QR Codes for RDLC reports is a straightforward .NET code process.
The library handles all encoding logic automatically, supporting standard, Unicode, and GS1-compliant text.
All configurations work for both ASP.NET and WinForms projects, as well as Crystal Reports.
Encode Standard ASCII Text
For regular ASCII text, you can directly assign the text string to the Data property.
Encode Unicode Multi-Language Text
Unicode text supports multi-language content (such as non-Latin scripts).
You can enable Unicode encoding with a single property toggle.
Always scan the QR Code to confirm accurate Unicode character decoding. Encode GS1-Compliant Text Messages
GS1-standard QR Codes are used for regulated retail, logistics, and healthcare data.
You can enable GS1 compliance by setting the FNC1 property to the correct value.
Test with GS1-certified barcode scanners to validate compliance. Guide to Custom QR Code Colors & High-Resolution Settings
The KeepAutomation .NET library lets you customize QR Code appearance and print quality.
These settings apply to both RDLC local reports and Crystal Reports without additional configuration.
Custom QR Code Color Styling
You can adjust foreground (QR Code module) and background colors for visibility or branding.
This works like customizing text and background colors in a standard document.
Note We recommend sticking to high-contrast color pairs for reliable scanning. Low-contrast colors may cause scanning failures with standard barcode readers. High-Resolution QR Code for Professional Printing
Higher resolution improves print sharpness, much like a high-DPI photo prints clearer.
A 300 PPI resolution is ideal for professional physical printing of RDLC reports.

Advanced QR Code Configuration Options for RDLC Reports
The KeepAutomation QR Code library supports all official ISO and GS1 QR Code standards.
These advanced options let you fine-tune QR Code behavior for specialized .NET reporting needs.

Frequently Asked Questions
What is "QR" short for in QR Code?
QR stands for "Quick Response Code." It is a modern, two-dimensional barcode that stores data in a square grid,
holds information both horizontally and vertically.
What's a better alternative to a QR Code?
There are other 2D barcode formats with features similar to QR Codes. One example is Data Matrix,
it's popular in industrial settings, including manufacturing and logistics.
What's the smallest possible printed size for a QR Code?
The QR Code ISO specification doesn't define a minimum size.
However, a 2 x 2 cm print size is a widely accepted guideline for reliable scanning by most smartphones.
Do colored QR Codes (not black and white) still function?
QR Codes can be black and white, or you can use colors as long as there's sufficient contrast between the code and background for scanners to read it.
How much information can fit in a single QR Code?
The largest standard QR Code (Version 40) can store about 7,089 numbers, 4,296 letters and numbers, 2,953 bytes of binary data,
or 1,817 Japanese Kanji characters when using low error correction.
