Date/Time Range Validator for ASP.Net

Question

It looks like the standard asp.net 2 RangeValidator control doesn't allow times. e.g. 01/01/2008 12:00 is not accepted in my range, even though it should be valid. If I remove the time it works as expected.

Is there a validator out there that allows for date/time format?

Update

We don't have Ajax extensions. Ideally, would like a preexisting control or a regular expression to use with CustomValidator. Validation should be client side, the server validation part is easy.

Solution

We used this RegExp:

Answer 1

You could use a custom validator and perform the check manually.

Here's a quick example or you can Google "asp.net custom validator". If you exclude the "ControlToValidate" property then you can validate against multiple fields.
