Clear Time Column
I have a datetime column which represents time with eidtMask hh:mm and format hh:mm. If I write something to this field then I can't clear it so as to become null. It will show 00:00 and treat it midnight. In some cases I have written code to handle this situation (user selects all and presses backspace), but I would like to know if there is an easy way of doing this.
