Examples

The File picker sample demonstrates how to respond to a FileSavePicker activated event.

// 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 contains a FileSavePickerActivatedEventArgs object. Additionally, the OnFileSavePickerActivated is in the App.xaml.cs file and the Activate method is in the FileSavePickerPage.xaml.cs file of the File picker sample.

Remarks

If your app participates in the File Save Picker contract, you can access this object using a fileSavePickerUI property while you handle a FileSavePicker activated event.

Use the FileSavePickerActivatedEventArgs.FileSavePickerUI property to retrieve a fileSavePickerUI object.
