    ASP.NET Validation Control works at client as well as server side. If browser supports javascript , then ASP.NET validation controls can perform validation using client script.
    Client side validation is performed on users' browser before the data postback to server.
    Client side validation is fast because there is no trip to server.
    Server side validation occurs at server. Server side is more secure nd ensures that no invalid data gets processed by the application.
    You can choose client side or server side or both.
