This isn't as stupid as you think, he may want to use the asp.net validators on the client sideChris S– Chris S2010-01-05 15:23:33 +00:00Commented Jan 5, 2010 at 15:23

Check out jQuery and the jQuery validation plugin which will handle these either directly or via the ability to extend the validation rules. That's the code that I would use.

For the age validation you can use a RangeValidator and for the mobile number you can use a RegularExpression validator.

- For age you will want a validator that restricts the textbox to numbers only
- For mobile number, you will want numbers only, and also "+" and maybe "-"
I don't want to write a tutorial on validator controls here, but you'll need a RangeValidator* for the age and a RegularExpressionValidator with two regexes and a ValidationSummary control for the error messages. Set EnableClientScript on the two validators to true.
There's a large amount of How Tos on the MSDN site.
* I suggested the wrong one there initially and copied George for RangeValidator
