Regular expression for validating date format mmddyyyy in asp net

I am not expert in writing regular expressions so need your help. I want to validate date in "dd-MMM-yyyy" format i.e. It's located under the ...\CFIDE\scripts directory. I just copied it into my project directory to include it like this: Then you can access all the javascript functions for cfform.So instead of using a Submit input type, make it a button.And it does work brilliantly except the fact that it cannot validate for months which have less than 31 days for example 30/02/2014 will be considered as a valid date. Net validators that post back methods should always check for Page.

Also, if you restrict the keypresses to certain keys only, you can still bypass it by clicking in that text box and pasting text from somewhere else.

I want date in a dd/mm/yyyy format with validation in Text Box . As I got date with dd/mm/yyyy but it will also accept 32/02/2005. Also when I compare two textbox it will not evalute properly. So I had used Compare Validator, & select type="date" but it will not evalute. Thanking You, One thing that must be kept in mind when using Asp.

Is Valid value that tells the page if validators returned true or false and then proceed further.

:1[6-9]|[2-9]\d)\d))$)$ You could use a Custom Validator and have the client-side validation be simple and on the server-side use a Date Time. Although I suspect you don't need your code to work all the way to the year 9999 (no, I couldn't immediately see if the supplied regexes work that far into the future).
