Remarks

Learn more about providing your app as a location where the user can save files in the Windows.Storage.Pickers.Provider namespace reference.

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.

Windows Store apps 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.

Examples

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();
    FileSavePickerPage.Activate(args);
}

// 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;
    this.OnNavigatedTo(null);
    Window.Current.Activate();
}

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.
