>Is there a way to display a message to the user when they enter an invalid date. (British Format) 31/06/2005. At the moment when our users enter invalid dates the textbox does not display any message to the user to inform them that the date is invalid, and we have found some users re-booting their machines because the application gives the impression that it's locked up inside the textbox and you can't get out of it.
