回答1:

To display blank you can set it as

DateTimePicker1.Format = DateTimePickerFormat.Custom;
DateTimePicker1.CustomFormat = "";

and then reset the format in ValueChanged event to the desired format. The picker doesn't allow null values since it requires a valid DateTime object.

You may choose to have a custom control also as found here
