If the field is null, I want the calendar to show no date. I cannot pass a predefined date or today's date because this is for the date a project is complete, and if the project is still in progress, that would be very confusing. I tried passing "12:00:00 AM" and Nothing and DBNull.Value, but nothing seemed to work. The error I'm getting seems to be dealing with converting strings to dates and junk like that.
