Question

Is there a template reverse order in Listbox? I’m using ObservableCollection and I would like to avoid any extra sorting, inserting etc.

If you use Linq, you should be able to just .OrderByDescending()? Have a look at an example here – http://msdn.microsoft.com/en-us/vcsharp/aa336756.aspx

If this is for the score list you were working on from a previous question, you should be able to just order by the score amount if it’s stored as an integer, without having to create a custom comparer function. An example linq query to order your list would be something like:

        var sortedItems =
            from item in myObservableCollection
            orderby item.Score descending
            select item;

Once you have the IEnumerable result of the Linq, you can recreate an ObservableCollection and reassign to your ViewModel (Cast LINQ result to ObservableCollection)
