This example demonstrates form validation using Data Annotation attributes. Type a number in the input element. If the input value is a valid number, the input will be ready to submit. Otherwise, an error message will be displayed until you enter a valid number.
The form enables validation with data annotation attributes when the submit button is clicked externally. All validation rules are enforced by the DataAnnotationsValidator component.
Age Field Validation Rules:
| Field | Rule |
|---|---|
| Required | The field must have a valid number. |
| Range | The field must have a number value between 1 and 80. |
