Remarks

If the editor’s value is set to null, DBNull or BaseEdit.NullValue and the ShowNullText property is set to true, the editor displays the text specified by the BaseEdit.NullText property and returns the value specified by the BaseEdit.NullValue property. If the ShowNullText property is set to false, the BaseEdit.NullValue property is not used, and the editor returns String.Empty.
