Answer 1

You can check if your binding source delivers a "null date" or a date value that you don't want to display.

If so, select custom format:

yourDTP.Format = DateTimePickerFormat.Custom
yourDTP.CustomFormat = " "

Add a "CloseUp" or "ValueChanged" event handler to reset the format on user action:

yourDTP.Format = DateTimePickerFormat.Short
