Hi Jacek,
this will be a little problem, because
DateTime isn't a nullable typ. A workarround
is to develop an own user control. On this you
should first place a DateTimePicker control
and after that you add a TextBox control
and place it over the input field of the
DateTimePicker. So every time you wouldn't
show a DateTime value within the DateTimerPicker
you show the empty TextBox and set the DateTime
value of the DateTimePicker to a value that
show that there's no DateTime. If the user
then choose a DateTime you hide the TextBox
and show the DateTimePicker.
Cheers
Lars Behrmann
