Hi,
As mentioned I didn't give *any* thought to the logic in the return line. My guess is that, as it stands, it would give ascending rather than descending order and so will need to be adjusted...
Best,
Viv

>>         public int Compare(DateTime x, DateTime y)
>>        {
>>            return x.CompareTo(y);
>>        }
>>     }

Return logic might be wrong but you get the idea. HTH
