The IAsyncAttachedCollectionSource type exposes the following members.

Properties

	Name	Description
	HasItems	Determines whether this IAttachedCollectionSource has any items. (Inherited from IAttachedCollectionSource.)
	IsUpdatingHasItems	Determines whether the HasItems property is currently being updated. Because updating HasItems may be an asynchronous operation, consumers of the IAttachedCollectionSource may want to wait for this property to become false before deciding that there are no items.
	Items	Gets (and creates, if necessary) the collection of items associatedwith this IAttachedCollectionSource. (Inherited from IAttachedCollectionSource.)
	SourceItem	Gets the object used to create this IAttachedCollectionSource. (Inherited from IAttachedCollectionSource.)

Events

	Name	Description
	PropertyChanged	Occurs when a property value changes. (Inherited from INotifyPropertyChanged.)
