Frame.NavigationFailed Event
Occurs when an error is encountered while navigating to the requested content.
Namespace: System.Windows.Controls
Assembly: System.Windows.Controls.Navigation (in System.Windows.Controls.Navigation.dll)
The following example shows the XAML for a frame that includes an event handler for the NavigationFailed event.
<sdk:Frame x:Name="ContentFrame" Style="{StaticResource ContentFrameStyle}" Source="/Home" Navigated="ContentFrame_Navigated" NavigationFailed="ContentFrame_NavigationFailed"> <sdk:Frame.UriMapper> <sdk:UriMapper> <sdk:UriMapping Uri="/ProductDetail/{productid}" MappedUri="/Views/ProductDetail.xaml?ProductId={productid}"/> <sdk:UriMapping Uri="/Reports/{type}/{selection}" MappedUri="/Views/ReportsPage.xaml?type={type}&selection={selection}"/> <sdk:UriMapping Uri="/{pageName}" MappedUri="/Views/{pageName}.xaml"/> </sdk:UriMapper> </sdk:Frame.UriMapper> </sdk:Frame>
The following example shows a handler for the NavigationFailed event. When navigation to a page within the frame fails, a child window is displayed that contains an error message and the URI of the requested page. The code for the child window named ErrorWindow is not shown in this example, but must be included in the application for the example to work. The Handled property is set to true to indicate that the event has been handled and an exception should not be thrown.
