Validating Values
Updated on Sep 30, 2026
The Kendo UI for Angular QR Code package provides the createQRCodeValidator function for Angular Reactive Forms. The validator checks whether a value is valid for the selected QR Code encoding.
The function accepts the QRCodeEncoding value ISO_8859_1 by default. Pass UTF_8 to validate Unicode values. When validation fails, the control receives a qrcode error that includes the validation message, value, and encoding.
The following example demonstrates the QR Code validator in action.
