WPF binding - How to bind direction of CollectionViewSource

Hi,

I am unable to bind the Direction property of a CollectionViewSource to a dependency property in my MainWindow.Xaml.cs

I get an error that "Binding must be to a dependency property".. and it is...


CollectionViewSource x:Key="peopleView" x:Name="peopleView"
                                  Source="{Binding Source={StaticResource people}}">
                <CollectionViewSource.SortDescriptions>
                    <scm:SortDescription PropertyName="Name" Direction="{Binding ?????}">


                    </scm:SortDescription>

                </CollectionViewSource.SortDescriptions>

            </CollectionViewSource>

Direction is not a dependency property and hence you cannot bind to it. Alternatively, you could create a data triggner to set the Direction based on a value.
