#612 – Application Event Sequence for Page-Based Applications

When you create a page-based application in WPF, you use a NavigationWindow as the main window, which in turn hosts one or more Page objects.  (If you set the StartupUri property of the Application to point to a Page, a NavigationWindow will be created automatically).

The sequence of Application events that fire for a page-based application are listed below.

When you start the application (assuming that a Page is specified as the StartupUri):

• Startup
• Navigating
• Navigated
• LoadCompleted
• Activated

When you shut the application down normally:

• Deactivated
• Exit

When you navigate to a new Page:

• Navigating
• NavigationProgress  (1 or more times)
• Navigated
• LoadCompleted

User is logging out of or shutting down Windows:

• Deactivated
• SessionEnding

Application gains focus:

• Activated

Application loses focus:

• Deactivated
