Blazor Input Mask - Form Validation Integration
This example is used to validate form using the Data Annotation. Type the value in the input element. If the input value is valid, then the given input will be ready to submit. Otherwise, an error message will be shown until you enter the valid value.
The form enables the validation with data annotation attributes by clicking on the submit externally. All rules are validated by the DataAnnotationsValidator.
The above phone number field is configured with the following rules.
| Field | Rule |
|---|---|
| Required | The field must have a valid value. |
| MinLength | The field must have more than 10 characters length. |
