To the best of my understanding, when client side scripting is disabled, then server-side validation will still take place. The difference being that now it does a PostBack before returning with the results of the validation. That's why my second suggestion was to check the success/failure of validation in the code behind (Make use of Validate() & IsValid), and based on the IsValid property do different things.

To validate server side, which you should do anyway, write C# code to make sure the values are within the expected range.
