Imagine there is a TDateTimePicker on the form which displayed my birth date which is 11/12/1978. When I have the DateTimePicker dropped down, and I will see a calendar. I don't click on any of the date and then I click anywhere outside the calendar and the datetimepicker. And it results in the calendar being closed up. At the same time, the date is changed to current date. What can I do to prevent the change of my birth date to current date?
