Adaptive and interactive toast notifications let you create flexible pop-up notifications with more content, optional inline images, and optional user interaction. You can use pictures, buttons, text inputs, actions, and more!

The ToastNotificationService is in charge of sending notifications directly from code in the application. The service contains a method ShowToastNotification() that sends a notification to the Windows action center. The code in this feature also includes a ShowToastNotificationSample class that shows how to create and send a notification from code.
ToastNotificationsService extends ActivationHandler to handle application activation from a toast notification. This code is not implemented on the template because the logic is application dependent. The following contains an example of one way to handle application activation from a toast notification.
Check out the activation documentation to learn more about handling app activation.
The relevant parts of the sample app that handle activation are shown below.
// ToastNotificationService.cs
protected override async Task HandleInternalAsync(ToastNotificationActivatedEventArgs args)
{
// Handle the app activation from a ToastNotification
NavigationService.Navigate<Views.ActivatedFromToastPage>(args);
await Task.CompletedTask;
}
// ActivatedFromToastPage.xaml.cs
protected override void OnNavigatedTo(NavigationEventArgs e)
{
base.OnNavigatedTo(e);
ViewModel.Initialize(e.Parameter as ToastNotificationActivatedEventArgs);
}
// ActivatedFromToastViewModel.cs
public void Initialize(ToastNotificationActivatedEventArgs args)
{
// Check args looking for information about the toast notification
if (args.Argument == "ToastButtonActivationArguments")
{
// ToastNotification was clicked on OK Button
ActivationSource = "ActivationSourceButtonOk".GetLocalized();
}
else if(args.Argument == "ToastContentActivationParams")
{
// ToastNotification was clicked on main content
ActivationSource = "ActivationSourceContent".GetLocalized();
}
