IActiveViewEvents Interface

Provides access to events that occur when the state of the active view changes.

When To Use

Use this interface to listen for specific events related to the active view, such as AfterDraw and SelectionChanged. Many CoClasses implement this interface and each fires events differently. For example, the Map object does not fire the FocusMapChanged event, whereas the PageLayout object does. Similarly, the Map object fires the ItemDeleted event when a layer is removed from the Map and the PageLayout fires the same event when elements such as a map frame or graphic are deleted.

Be aware of the specific object's events to which you are listening. For example, writing code to listen for the SelectionChanged event on just the FocusMap object will not fire an event by changing the selection in layout view. Also, if the focus map changes you must reset the client.

The AfterItemDraw event will only be fired when the IViewManager::VerboseEvents property is set to True. By default, this property is set to False.
