Pages.PageChanged Event (Visio)
Occurs after the name of a page, the background page associated with a page, or the page type (foreground or background) changes.
If several pages of a document have default names and any page but the last is deleted, Microsoft Visio will automatically rename the remaining pages to preserve the naming sequence, but the renaming will not trigger the PageChanged event. For example, if a document contains Page-1, Page-2, and Page-3, and then Page-1 is deleted, Page-2 will be renamed Page-1, and Page-3 will be renamed Page-2, but no PageChanged event occurs.
If you're using Microsoft Visual Basic or Visual Basic for Applications (VBA), the syntax in this topic describes a common, efficient way to handle events.
If you want to create your own Event objects, use the Add or AddAdvise method. To create an Event object that runs an add-on, use the Add method as it applies to the EventList collection. To create an Event object that receives notification, use the AddAdvise method. To find an event code for the event you want to create, see Event codes.
