IXRNotifyCollectionChanged
Methods
| Method | Description |
|---|---|
Retrieves the CollectionChanged custom event defined in a collection object. The collection object must raise this event when the collection changes. |
Thread Safety
Members of this class are thread-safe if you previously called IXRApplication::CreateHostFromXaml and supplied it with an XRWindowCreateParams structure that has AllowsMultipleThreadAccess set to true.
Remarks
Implement this class on a custom collection object. Then, use this class to update the user interface when the collection changes. The action that caused a collection to change is defined in the XRCollectionChangeAction enumeration, which you can retrieve from the CollectionChanged event data. An IXRItemsControl registers a CollectionChanged event handler.
When you create a class instance, use an IXRNotifyCollectionChangedPtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.
.NET Framework Equivalent
