RegularExpressionValidatorI have a textbox that can take a two-digit number (15-99) OR a date in
mm/dd/yyyy format. The validation expression I am trying to use is: (([15-99])|((0[1-9]|[12][0-9]|3[01])[/](0[1-9]|1[012])[/](19|20)\d\d)). This does not work and the validator is firing even when valid entries are made. It is clear I have missed something in my formula. Any help would be much appreciated. Thank You. Nevermind. I found the solution:
^\d{2}$|^(((0?[1-9]|1[012])/(0?[1-9]|1\d|2[0-8])|(0?[13456789]|1[012])/(29|30)|(0?[13578]|1[02])/31)/(19|[2-9]\d)\d{2}|0?2/29/((19|[2-9]\d)(0[48]|[2468][048]|[13579][26])|(([2468][048]|[3579][26])00)))$
