Implementing Barcodes (SfBarcode)

The Syncfusion WinUI Barcode control (SfBarcode) generates and displays data in machine-readable barcode formats. It supports both one-dimensional (linear) and two-dimensional barcodes with extensive customization options for appearance, text display, and symbology-specific settings.

When to Use This Skill

Use this skill when you need to:

• Generate barcodes or QR codes in WinUI applications
• Encode text, numbers, or data into machine-readable formats
• Display product codes, inventory labels, or shipping information
• Create scannable codes for mobile devices (QR, DataMatrix)
• Implement barcode printing functionality
• Customize barcode appearance (colors, rotation, text display)
• Choose appropriate symbology for specific data types
• Configure symbology-specific settings (error correction, encoding, checksums)

Component Overview

Key Capabilities:

• 15 Symbology Types: 12 one-dimensional + 3 two-dimensional barcode formats
• Flexible Text Display: Customizable alignment, spacing, and visibility
• Visual Customization: Colors, bar widths, rotation angles
• Symbology Settings: Type-specific configurations (checksums, encoding, error correction)
• XAML and Code-Behind Support: Declarative and programmatic implementation

Common Use Cases:

• Product labeling (UPC, EAN codes)
• Inventory management (Code39, Code128)
• Shipping labels (GS1-128, DataMatrix)
• QR codes for URLs, contact info, Wi-Fi credentials
• Document tracking (Code93, PDF417)
• Healthcare labels (Code32 pharmaceuticals)

• QR Code: QRVersion (1-40 or Auto), ErrorCorrectionLevel (Low/Medium/Quartile/High), InputMode (Numeric/AlphaNumeric/Binary)

Quick Start

Minimal Barcode Implementation

XAML:

<Page xmlns:syncfusion="using:Syncfusion.UI.Xaml.Barcode">
    <Grid>
        <syncfusion:SfBarcode x:Name="barcode" 
                               Value="48625310"
                               Height="150">
            <syncfusion:SfBarcode.Symbology>
                <syncfusion:CodabarBarcode />
            </syncfusion:SfBarcode.Symbology>
        </syncfusion:SfBarcode>
    </Grid>
</Page>

C#:

using Syncfusion.UI.Xaml.Barcode;

SfBarcode barcode = new SfBarcode();
barcode.Value = "48625310";
barcode.Height = 150;
barcode.Symbology = new CodabarBarcode();
Root_Grid.Children.Add(barcode);

QR Code for URL

<syncfusion:SfBarcode x:Name="qrCode" 
                       Value="http://www.syncfusion.com"
                       Height="200"
