Hello Alan,
You can't really. You can assign DbNull, but DateTime is a valuetype, therefore
no null...

But, if you are using C# 2.0, you can use Nullable<DateTime> which can be
set to null and you can detect that, setting the database to DbNull where
appropriate.

Hi,
Will the DateTimePicker accept nullable types?
AFAIK it does expect a DateTime.
