Example: Binding Sorted ObservableCollection to an ItemControl-Derived Control
ObservableCollection<LookupListItem> lookupList = DataCache.GetLookupList();
CollectionViewSource collectionViewSource = new CollectionViewSource();
collectionViewSource.SortDescriptions.Add(new
System.ComponentModel.SortDescription("ItemName",
System.ComponentModel.ListSortDirection.Ascending));
collectionViewSource.Source = lookupList;
this.DataContext = collectionViewSource; // sorted data
Set ItemSource of the ItemsControl-derived control (combobox in this case)
to {Binding} so that the control gets the sorted data from the DataContext
which holds the sorted CollectionViewSource:
<ComboBox x:Name="theList" Grid.Column="0"
DisplayMemberPath="ItemName" ItemsSource="{Binding}"/>
