Public Custom Event Failed As TypedEventHandler(Of ToastNotification, ToastFailedEventArgs)

Event Type

TypedEventHandler<ToastNotification,ToastFailedEventArgs>

Remarks

The reason for the toast's failure can be found in the ErrorCode property of the ToastFailedEventArgs parameter.

The most common failure that you'll see when you raise a toast is a settings error, for instance a block on toast notifications for this user. We recommend that you call ToastNotifier.Setting before you call Show instead of handling that situation through this event.
