What's your preferred approach to the sortable ObservableCollection in WPF?

Question

This article "Write a Sortable ObservableCollection for WPF" appears to be all that's needed (for me) to handle any need to sort ObservableCollection. However, there might be scenarios that need a more complex design. Or, on the other extreme, there may be a way to prevent this need for a sort by design. Am I on the right track here or is this question moot?

Answer 1

This depends on whether you are trying to persist the user-selected ordering, like if the user is prioritizing items.

If the sorting is for display purposes only as is more common, CollectionView and CollectionViewSource are well-adapted to sorting and filtering collections in various ways in the WPF UI.

Answer 2

I have created one application that allows you to Sort, filter, implace editing based on User interaction.

You can check this out, it might help. Sorted ObservableCollection is basically very expensive.
