for make datetimepicker column, I'd referenced upper link's post.
when i insert only date, the time is remains with previous value.
1. insert '2013-05-05 11:11:00' by type, then end edit
2. update '2013-05-06' by type, then end edit
then value become '2013-05-06 11:11:00'
I want get value '2013-05-06 00:00:00' at this case
because user did not insert time value.
how can i get date without time when user did not insert time?
