Asp.Net MVC is a great framework. But, developers coming from Webforms background will find it little bit difficult not having a set of Validation controls which automatically validates form input by user. JQuery is a part of Asp.Net MVC application and I just found a nice JQuery plugin which fills the gap of Validator Controls of Webforms. It can be downloaded from here.

There are enough examples which coveres most of the routine validation needs and using it is as easy as Webforms validator controls.
