The File picker contracts sample demonstrates how to respond to a FileSavePicker activation point.

// fileSavePicker activated event handler
protected override void OnFileSavePickerActivated(FileSavePickerActivatedEventArgs args)
    var FileSavePickerPage = new SDKTemplate.FileSavePickerPage();

// Overloaded method to respond to fileSavePicker events
internal void Activate(FileSavePickerActivatedEventArgs args)
    // Perform tasks to prepare your app to display its file picker page

    // Get file picker UI
    fileSavePickerUI = args.FileSavePickerUI;

    Window.Current.Content = this;

For C#, args for an OnFileSavePickerActivated override on the Application object references a FileSavePickerActivatedEventArgs object. The OnFileSavePickerActivated override is in the App.xaml.cs file and the Activate method is in the FileSavePickerPage.xaml.cs file of the File picker contracts sample.

A FileSavePickerActivatedEventArgs object is passed to the app's activation point handler when the user saves a file through the file picker and selects the app as the location. This type of activation is indicated by the ActivationKind.FileSavePicker value returned by the Kind property.

Apps written in JavaScript must listen for and handle Windows.UI.WebUI.webUIApplication.activated events.

UWP app using C++, C#, or Visual Basic typically implement activation points by overriding methods of the Application object. The default template app.xaml code-behind files always include an override for OnLaunched, but defining overrides for other activation points such as OnFileSavePickerActivated is up to your app code.

All Application overrides involved in an activation scenario should call Window.Activate in their implementations.

This property returns the logged-in user on platforms that only support single-user sessions. For platforms that support multiple users in a session (such as Xbox) this property returns the logged-in user that the app was activated for.

This property returns null when a multi-user application is activated with no specific user context.

Multi-user apps can use this property to allow or restrict app behavior. For example, you might restrict access to content or features based on the user’s credentials.
