Progress Telerik UI for Blazor
Telerik UI for Blazor provides a set of validation tools to use with our Form component and the standard Microsoft EditForm). The validation tools consist of 3 components, each providing a different way to report issues with user input validation. The components follow the modern Telerik UI for Blazor design principles – they deliver many features out of the box, while being flexible to be placed in a variety of situations – like the ability to completely alter their visual by specifying a template or a CSS class.

The Validation Summary component groups together all issues with your form data in one place. It has the benefit of acting like a report of errors. Putting all messages in the same place makes it easy to identify that something went wrong (because the user sees a big red blob).
