You can use javascript functions

Refer this link for numbers and letters
http://answers.oreilly.com/topic/134-how-to-allow-only-numbers-or-letters-in-a-text-box-with-javascript/[^]

For Email:

C#

function validateEmail(email) {
    var re = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\
".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA
-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
    return re.test(email);
}

You can use the custom validator to achieve this. I recommend CustomValisator over RegularExpressionValidator for the reason that you also need the fields as required. This thing can be easily achieved using CustomValidator control

To get stared with Custom Validator control refer
1. Custom Validation Summary in ASP.NET[^]
2. http://asp.net-tutorials.com/validation/custom-validator/[^]

Once you use the CustomValidatorControl, you can put the regular expression in the javascript code to validate the data in the textbox
1. Regular Expression for Number only : [0-9]*
2. Regular Expression for Characters only : [A-Za-z]*
3. Regular Expression for Email : \b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b

Hope this helps.
All the best
