Standardization: Extended
Syntax kind: Modifier


When applied to a class or interface property, this indicates that the property returns an event object that event handlers can be attached to. The event-handling API is implementation-defined, but typically the property return type would be a class with members such as addHandler() and removeHandler(). A documentation tool can display such properties under an “Events” heading instead of the usual “Properties” heading.


class MyClass {
    * This event is fired whenever the application navigates to a new page.
    * @eventProperty
  public readonly navigatedEvent: FrameworkEvent<NavigatedEventArgs>;
