2)custom validation
3)self validation model.
4)Remote validation.
5)Server side validate.

Please help me.

You can do what ever you like. You should ALWAYS validate on the server, client side validation can be easily hacked. You can write client side code, too. It's possible to annotate your viewmodel, but only to the top level, so you can't have a class inside your viewmodel and then have the properties of that class be validated using the built in validation. For me, this is reason alone to never use it, but you can.

Just make sure you always validate on the server, and add client side validation for convenience, using whatever method you like.
