You should have a look at the ASP.NET Validators, e.g. the RangeValidator or RegularExpressionValidator:

With regular expressions you can restrict the input to pretty any kind of format. Of course you'll have to learn regular expressions for that, which i'd advice since they are helpful in a lot of cases.

But if i understand you right you like to validate the input before sending it to the server? In that case you'll need some client side validation which can be done e.g. with JavaScript. I updated the answer with another link to a very informative article about different ways of validation in ASP.NET. Have a look at that.
