A standard DateTimePicker control that enables users to enter null value. The fact that it's not intensively modified ensures that it has no potential errors.

Sample Image - Nullable_DateTimePicker.jpg


I had do a research on a DateTimePicker that could enter null value and found a lot of solutions to it. But one major problem with those is that they behave quite different from the standard ones and may have many potential bugs, as a result it took time to test before using in a real application. I just found another simple solution that could solve this problem with a little modification, so it could promise no bugs :-).


I have overridden the Value property to accept Null value as DateTime.MinValue, while maintaining the validation of MinValue and MaxValue of the standard control. That's all there's to it.

Because it's so simple, there's not much to say about it. Please refer to code for details.
