    or write a converter like stackoverflow.com/questions/5722835/… or expand the observableCollection. It may be possible to connect itemsource via ICollectionView and var desc = new SortDescription (MyProp, ListSortDirection.Ascending); myCollectionView.SortDescriptions.Add (desc); - user2455111

 collection_node = new ObservableCollection( collection_node.OrderBy(n => n.Name) );

    Good example how to use sort.
