NavigationService.NavigationFailed Event

 

Occurs when an error occurs while navigating to the requested content.

Namespace:   System.Windows.Navigation
Assembly:  PresentationFramework (in PresentationFramework.dll)

Public Event NavigationFailed As NavigationFailedEventHandler

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:

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.

Private Sub NavigationService_NavigationFailed(ByVal sender As Object, ByVal e As NavigationFailedEventArgs)
    Dim msg As String = String.Format("Navigation to {0} failed: {1}.", e.Uri.OriginalString, e.Exception.Message)
    Me.progressStatusBarItem.Content = msg
End Sub
