Windows Universal App Fullscreen Button

Windows Universal App Fullscreen Button

To implement a fullscreen button in a Windows Universal App, you can use the ApplicationView class and its TryEnterFullScreenMode and ExitFullScreenMode methods to enter and exit fullscreen mode.

Here's an example of how to implement a fullscreen button in a Windows Universal App:

private void FullscreenButton_Click(object sender, RoutedEventArgs e) { if (ApplicationView.GetForCurrentView().IsFullScreenMode) { // Exit fullscreen mode ApplicationView.GetForCurrentView().ExitFullScreenMode(); FullscreenButton.Content = "Enter Fullscreen"; } else { // Enter fullscreen mode ApplicationView.GetForCurrentView().TryEnterFullScreenMode(); FullscreenButton.Content = "Exit Fullscreen"; } }

In this example, we're using a Button control with a click event handler to toggle fullscreen mode. We're checking the IsFullScreenMode property of the ApplicationView class to determine whether the app is currently in fullscreen mode. If it is, we call the ExitFullScreenMode method to exit fullscreen mode and change the button text to "Enter Fullscreen". If it is not, we call the TryEnterFullScreenMode method to enter fullscreen mode and change the button text to "Exit Fullscreen".

Note that the ApplicationView class is part of the Windows.UI.ViewManagement namespace, so you will need to add a using statement for this namespace in your code file.
