Using Date Filter fails when row has a null date

[Timothy]

When using the row filter button for DateTime Columns if a row has a null value the filter fails.
This can easily be reproduced using the Demo samples by going into the Nwind.mdb and setting one of the Employees Hiring Dates to NULL and then going to Demo Samples for Winforms -> GridView -> Filtering -> Filtering and clicking the filter button under hiring and selecting Is not null.

Hi Timothy,

I also had this problem and filed a bug report. It's fixed with 2012 Q1 SP1 Internal Build 403.
