In WPF, the CollectionViewSource allows for sorting (SortDescriptions) and grouping (GroupDescriptions). However, I can't find a way to order the groups. Is it possible?

See Question&Answers more detail:os<CollectionViewSource x:Key="cvs" Source="{Binding Source={StaticResource animals}, Path=AnimalList}">
<CollectionViewSource.GroupDescriptions>
<PropertyGroupDescription PropertyName="Category"/>
</CollectionViewSource.GroupDescriptions>
<CollectionViewSource.SortDescriptions>
<scm:SortDescription PropertyName="Category" />
<scm:SortDescription PropertyName="Name" />
</CollectionViewSource.SortDescriptions>
</CollectionViewSource>
Just add two SortDescriptions.Adding two sort descriptions allows us to sort the groups first and then the items within the groups.
