I'm working in a grid with two fields, one for effective date and the other for retirement date with the retirement date defaulting to DateTime.MaxValue. When I edit the field (inCell mode, if that matters) on the effective date all is well and I get what I'm expecting - MM/dd/yyyy format. However, when I edit the retirement date I get the full date and time format no matter how many different places I specify the format. To test this, I changed the date manually and was able to do so up until December 31st, 2099. After that date, the field went blank. Has anybody else noticed this? Ideas for a workaround other than adding a checkbox for the max date in the template?
