Hi.In Asp.net which validation should be preferred,Server-side or Client-side? and why?

Actually there is only one validation control which provides server-side validation.
That is Custom Validator.
That means i have to use only this control?
Can you gimme a simple example?

It depends, If security is concerned more than performance then server side validation is must,

Great if you use Asp.net Validation controls, because it does both, It fires server side validation if client side validation fails
