Blazor TextArea Example - Form Validation Integration Support
This example demonstrates form validation using Data Annotation attributes. Type the value in the textarea. If the input value is valid, the input will be ready to submit. Otherwise, an error message will be displayed until you enter a valid value.
The form enables validation with data annotation attributes when the submit button is clicked externally. All validation rules are enforced by the DataAnnotationsValidator component.
