Adding validation to a form

In this recipe, we’ll explore the basics of user input validation in Blazor. Validation is critical for preventing errors and security vulnerabilities, maintaining data consistency, and enhancing the user experience. The Blazor community has created various NuGet packages for handling input validation, offering a range of features and configurations. However, Blazor provides extensive built-in support for validating forms and displaying validation results in a user-friendly manner. The native functionalities are lightweight and integrate directly with Blazor’s data binding and UI features.

Let’s implement a small event creation form, where a user must provide the event name. We will also display a validation message when the event name is empty.

Getting ready

Before we add the first, basic validation to a form, create a Chapter07/Recipe01 directory – this will be your working directory.
