Am trying to implement some sort of validation on a text box, that users would input dates into. I need help on writing VB code, such that when users fill there date of birth into the text box, it prevents them from putting a date in the future. Also for a text box that requires a date in the future, the validation should prevent them from picking a date in the past.

View 4 RepliesI have a web application (done in ASP/C#) that has regex validation on a text box. Initially the regex works perfectly fine. But then I also provide a button click event (clear) that allows the user the clear text box and change their input for a new query. At this point (page post back) the regex takes control and maintains control of the text box so a new query can't be run. Can anyone tell me what to do so that the regex doesn't fire on page postback and allows new input for validation?
