collectionChanged Event

Current information about Live Connect is now available in the Windows Live Developer Center. The information in the following sections is provided for legacy purposes only.

Occurs when the collection changes.

Script:  http://js.live.net/4.1/loader.js
Feature:  Microsoft.Live.Services
Namespace:  Microsoft.Live.Services
 

// Your event handler:
function collectionChanged(sender, e) {
    // Event handling code
}

// To add the handler:
instance.add_collectionChanged(collectionChanged);

// To remove the handler:
instance.remove_collectionChanged(collectionChanged);

To raise this event, use the raiseCollectionChanged method.

When the collection changes, you can designate a JavaScript function to invoke by subscribing to the event with the following syntax add_collectionChanged(handler) where handler is the function to call. The function specified takes a CollectionChangedEventArgs as a parameter.

The following example demonstrates how to use the collectionChanged for a ContactCollection class.

            dataContext.loadAll(Microsoft.Live.DataType.contacts, function (contactsLoadedEvent) {
                if (contactsLoadedEvent.get_resultCode() != Microsoft.Live.AsyncResultCode.success) return;
                var contactsCollection = contactsLoadedEvent.get_data();
                contactsCollection.add_collectionChanged(contactsCollectionChanged);
            });
            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();
            }
