Grouping only works in WPF and Silverlight. It is ignored in WinForms because WinForms data binding does not support grouping.
When a GroupDescriptor is applied, the data will inherently be sorted by the grouped property. To force a grouped property to be sorted in descending order, add a SortDescriptor to the SortDescriptors collection for that property using the Descending direction.
