The SearchableObservableArrayList class is a base class that provides the functionality for change notification for the DataCollection class. The SearchableObservableArrayList class can be used to search for items in the collection.

The following example demonstrates how to use the functionality of the SearchableObservableArrayList class in a derived ContactCollection class.

            dataContext.loadAll(Microsoft.Live.DataType.contacts, function (contactsLoadedEvent) {
                if (contactsLoadedEvent.get_resultCode() != Microsoft.Live.AsyncResultCode.success) return;
                var contactsCollection = contactsLoadedEvent.get_data();
            function contactsCollectionChanged(collectionChangedEventArgs) {
                var changedCollection = collectionChangedEventArgs.get_changedCollection();
                var countChanged = collectionChangedEventArgs.get_changedItems().length;
                if (countChanged == 0) return;
                var firstChangedItemName = (collectionChangedEventArgs.get_changedItems()[0]).get_firstName();
