False	false. DefaultBoolean.False has a constant value of 1, while the standard false value corresponds to a value of 0. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
Default	The default behavior determined by the control’s logic.

Default	The behavior is different for different editors: For the DateEdit and BlobBaseEdit descendants, the Default value is equivalent to True. For other editors, the Default value is equivalent to False.
