Sorting an observable collection with linq

Question

I have an observable collection and I sort it using linq. Everything is great, but the problem I have is how do I sort the actual observable collection? Instead I just end

Answer 1

If you are using Silverlight 3.0, then using CollectionViewSource is the cleanest way. Refer below example: (it can be done via xaml as well)

ObservableCollection ecAll = new ObservableCollection();
CollectionViewSource sortedcvs = new CollectionViewSource();
sortedcvs.SortDescriptions.Add(new System.ComponentModel.SortDescription("Date", 
    System.ComponentModel.ListSortDirection.Ascending));
sortedcvs.Source = ecAll;
ListBoxContainer.DataContext = sortedcvs;

And in corresponding xaml set

ItemsSource="{Binding}"

for the ListBox or any ItemsControl derived control
