Validating Values
Updated on Sep 30, 2026
The Kendo UI for Angular Barcode package provides the createBarcodeValidator function for Angular Reactive Forms. The validator checks whether a value is valid for the selected Barcode type.
Pass a BarcodeType to validate the value. You can also pass the optional barcode size when the selected type requires it. The validator accepts string and numeric values, returns null for empty values, and returns a barcode error with the validation message, value, and type when validation fails.
The following example demonstrates the Barcode validator in action.
