NavigationService.NavigationFailed Event
Occurs when an error occurs while navigating to the requested content.
Assembly: PresentationFramework (in PresentationFramework.dll)
When either a WebException or an IOException is thrown during a navigation, the NavigationFailed event is raised. NavigationFailed is passed a NavigationFailedEventArgs that encapsulates information about both the exception and the details of the navigation that caused the exception.
When an exception results from a failed navigation, and is unhandled, the following events are raised in the order listed:
NavigationService.NavigationFailed.
Frame.NavigationFailed or NavigationWindow.NavigationFailed.
If a navigator (NavigationWindow, Frame) is hosted by one or more navigators, NavigationFailed is not raised on any of them.
The following example shows how to handle NavigationFailed.
