DateTime to null

[Alan T]

How do I set a DateTime field to null ?
Hence set the DateTimePicker to null?

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.
