How to Display Local Toast in Universal Windows Apps

In this article I will show how to display local toast notifications in Universal Windows Apps. No backend is required to display local toasts. It can be triggered to show completion of some event or notify about some error in the task being executed.

Step 1: Setup the UI of your page to Trigger a Local Toast

We add a TextBox and Button on our page. On clicking the Button, TextBox’s Text will be displayed as a local Toast. We are keeping the MainPage.xaml in the Shared project itself as the UI for both Windows Phone and Windows app will be common for our sample project.

Step 2: Add a Toast Service class in the Shared project

We create a new ToastService class and add a static method ShowToastNotification which takes a string argument message to it.

This method is responsible for the following:

  • Set toast’s text to the message passed as argument
  • Set image source to some hardcoded value
  • Set toast’s duration. In our sample we are setting the duration to short.
  • Set toast’s navigation. This is the NavigationUri string which can be handled by the app to navigate to a particular page when the notification is tapped. Arguments can also be passed to it.
  • Create the toast notification based on the XML content you’ve specified.
  • Show the toast notification

Step 3: Add a Click event handler to trigger local toast

Add a click event handler for the Button to trigger a local toast to be displayed. In the code behind for the click event, the ShowToastNotification method is called with the TextBox’s text passed as an argument.

Here’s how the toast notification appears in the action center.

Feel free to download the full project’s source code or clone it from GitHub.
