Selection.PersistsEvents Property (Visio)
Indicates whether an object is capable of containing persistent events in its EventList collection. Read-only.
Every object that has an EventList property also has a PersistsEvents property. To be persistable, an event's action code must be visActCodeRunAddon, but it must also be in the EventList collection of an object whose PersistsEvents property is True. The only objects that currently persist events are Document, Master, and Page objects.
Whether a persistable event actually does persist depends on the value of its Persistent property.
This Microsoft Visual Basic for Applications (VBA) macro shows how to use the PersistsEvents property to determine if an object is capable of containing persistent events. Executing the macro prints 1 (True), 1 (True), and 0 (False) in the Immediate window for the Document, Page, and Window objects, respectively.
