Leveraging data annotations for form validation
In this recipe, we explore the role of data annotations in streamlining and enhancing the validation processes in a form in Blazor. Data annotations are attributes applied directly to model properties that enable a declarative way of specifying validation rules. By implementing data annotations, you can significantly simplify the validation logic and encapsulate it within the model rather than coupling it with any specific form. Such separation ensures that validation is consistently enforced across different parts of your application regardless of the context in which you use the model. Blazor has a built-in DataAnnotationsValidator component that seamlessly integrates data annotations into a form. DataAnnotationsValidator checks the data annotations applied to the model and produces validation results without additional coding.
Let’s convert an explicit validation logic in a form into data annotations and leverage Blazor&...
