We recommend installing the QueryString.NET NuGet package to help construct and parse query strings for your notification arguments, as seen below.

The first step in making your notifications actionable is to add some launch args to your notification, so that your app can know what to launch when the user clicks the notification (in this case, we're including some information that later tells us we should open a conversation, and we know which specific conversation to open). We often recommend combining OnLaunched and OnActivated into your own OnLaunchedOrActivated method since the same initialization needs to occur in both. OnLaunched is NOT called if the user clicks on your toast, even if your app was closed and is launching for the first time. You must initialize your frame and activate your window just like your OnLaunched code. ValueSet userInput = toastActivationArgs.UserInput Obtain any user input (text boxes, menu selections) from the notification String args = toastActivationArgs.Argument Obtain the arguments from the notification If (e is ToastNotificationActivatedEventArgs toastActivationArgs) When the user clicks your notification (or a button on the notification with foreground activation), your app's OnActivated will be invoked.Īpp.xaml.cs protected override void OnActivated(IActivatedEventArgs e) ToastNotificationManager.CreateToastNotifier().Show() Var notif = new ToastNotification(content.GetXml()) AddText("Check this out, Happy Canyon in Utah!") AddToastActivationInfo("picOfHapp圜anyon", ToastActivationType.Foreground) Construct the notification content (using the Notifications library), and show the notification! // Construct the content We'll start with a simple text-based notification. See the toast content documentation for more information. In Windows 10, your toast notification content is described using an adaptive language that allows great flexibility with how your notification looks. Windows.UI.Notifications includes the toast APIs. This package allows you to create toast notifications without using XML. At the end of the article we'll provide the "plain" code snippets that don't use any NuGet packages. Important APIs: ToastNotification Class, ToastNotificationActivatedEventArgs Class Step 1: Install NuGet package Please see the Win32 apps documentation to learn how to implement toasts. Win32 applications (including packaged MSIX apps, apps that use sparse packages to obtain package identity, and classic non-packaged Win32 apps) have different steps for sending notifications and handling activation.
