I think there is a bug with the DataTimeOffset field when used in a Grid. It cannot display correctly and is showing something like /Date(1364927400000)/. I have to retrieve my data from database as DateTimeOffset format and then use a new ViewModel to convert the DateTimeOffset values to DateTime values. This is really annoying.
Could you let me know if there is a way a DateTimeOffset field can be supported in the grid? Sometimes you do have to display the time zone info.
I hope this can be fixed in a future release.
