Occurs when there is a change in the set of this camera's layers.
The event handler receives an argument of type PPropertyEventArgs containing data related to this event. The following PPropertyEventArgs properties provide information specific to this event.
|NewValue||Gets the new value of the property that changed.|
|OldValue||Gets the old value of the property that changed.|
When a user attaches an event handler to the LayersChanged Event as in LayersChanged += new PPropertyEventHandler(aHandler), the add method adds the handler to the delegate for the event (keyed by PROPERTY_KEY_LAYERS in the Events list). When a user removes an event handler from the LayersChanged event as in LayersChanged -= new PPropertyEventHandler(aHandler), the remove method removes the handler from the delegate for the event (keyed by PROPERTY_KEY_LAYERS in the Events list).
