I read about it on MSDN and many forums and understood that any value with its date portion as 1900-01-01 is treated as null, but user doesn’t see completely empty field, user sees 00:00:00 or 12:00:00 am (depends on the time format settings on user’s computer). So my question is, can I make UTCDateTime field completely empty when it holds the null value
That’s how the form control works. You can hide the time part if you don’t need it, but I don’t think you can display time as empty space.
