Only validating on the client is a bad idea, and insecure. You need to ALWAYS do server side validation, and only do client-side validation as a "nice to have". Otherwise validation can be bypassed by any attacker just by bypassing the client-side script.

There are several ways to do server (and client) side validation without data annotations. You can use Metadata "buddy" classes and apply the attributes to the buddy class. Or you can use Fluent Validation. You can also use IValidatableObject. You really really really should use some kind of server side validation though.

In mvc 3, With Model DataAnnotations You can do javascript validations in client side. It uses jquery validate script to do the validations.

in ASP.NET MVC 3 Beta, we’ve updated the runtime to enable a feature we’re calling “Unobtrusive Client Validation”. We have also created a consumer for these unobtrusive client validation attributes that uses jQuery and jQuery Validate to perform the validation on our behalf.

You should never rely on client side validation only. Do both client side and server side. What if somebody is accessing your website from a javascript disabled browser ?
