Blazor ValidationSummary

Overview

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.

Validation Summary

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).

Templates

Control the appearance of your error messages by providing a template to the component. Modify the visual style to match the rest of the application and make sure the errors are easily noticeable and focus the user's attention.

Localization

The Telerik ValidationSummary component can easily pick the correct error message to display depending on the active app language so your app is available to everyone in the world.
Right-to-Left (RTL) Support

The Telerik UI for Blazor Validation Summary component supports right-to-left configuration. The RTL functionality is supported my most of our components to accommodate users who communicate in a right-to-left language script, such as Arabic and Hebrew.
