Decimal fields are automatically validated by the default model binder. You don't need to do anything special. If you try to assign an invalid value to a decimal field on your view model you will get a validation error.

@senzacionale, what about it? – Darin Dimitrov Oct 16 '11 at 09:22
i want that no one can write value larger than 10,3 – senzacionale Oct 16 '11 at 09:25
@senzacionale, ah, you would use the `[Range(min, max)]` attribute. Take a look here: http://stackoverflow.com/questions/7256753/min-max-value-validators-in-asp-net-mvc – Darin Dimitrov Oct 16 '11 at 09:27

I hope it will helps you.... create a custom validator that uses Decimal.TryParse under the covers.

Don't use regexes for these things. They'll break badly with localization. – xanatos Oct 16 '11 at 09:08
