How can I customize AJAX validation in ASP.NET MVC?

You can customize AJAX validation in ASP.NET MVC by using the Remote attribute in your model and creating a custom validation method.

Can you show me an example of how to implement that?

Sure! First, add the Remote attribute to your model property. Then, create a controller action that returns a JSON result based on your validation logic.

What if I want to add custom error messages?

You can specify custom error messages in the Remote attribute by using the ErrorMessage property. This allows you to provide user-friendly feedback.

Is there a way to validate multiple fields at once?

Yes, you can create a custom validation method in your controller that checks multiple fields and returns a single JSON response with the validation results.
