Hi

I have the regular expression to validate date (mm/dd/yyyy) with <asp:regularexpressionvalidator> but its not validating leap years, can anyone help with the regex, the code that I am using is as below:

<asp:regularexpressionvalidator id="regExpRequestDate" runat="server" ControlToValidate="txtRequestDate" ErrorMessage="(mm/dd/yyyy format)"
                                ValidationExpression="^[0-2]?[1-9](/|-)[0-3]?[0-9](/|-)[1-2][0-9][0-9][0-9]$"></asp:regularexpressionvalidator>

Regards
Mike

Oops!

No need to worry friends, I sorted it out, I used the compareValidator to check date, thanx for your efforts.

Here you go anyway! This will check a valid date as well as a leap year. excepts date as d.m.yy or dd/mm/yy etc.

I will only tell you how to do it, not do it for you.
Unless, of course, you want to hire me to do work for you.

Thanx Parsons

This works as well :)
