I am facing similar problem. When I define field.DataType = typeof(DateTime), cell just displays Date and no time, how do I make sure cell displays date and time.

If date format is d/M/yy then sorting fails as number are single digits so sorting order becomes

1,11,13,14,2,21,22, 3,30 where as it should be like 1,2,3,13,14,21.

I am sure this is basic issues and might already be addressed.

please advise.

Thanks,

Mahesh
