With JavaScript turned off, what may not be known is that, on the server side, even though the validators fire, it is left to the developer on how to use that information.

You may think you have built a secure application but a hacker could disable JavaScript and bypass all your validators! This is where the Page.Validate method and more importantly, the Page.IsValid property come in.

There are a number of ways around the client-side validators. In the extreme case, the user could simply download the page and modify it in any way they want. There's no way to control that.

In most cases, the client-side validation controls will work just fine. But you should always verify data is valid on the server just in case.
