Esempio

Questo codice di esempio prepara la pagina per l'uso di ContactPickerUI:

ContactPickerUI contactPickerUI = MainPagePicker.Current.contactPickerUI;
CoreDispatcher dispatcher = Window.Current.Dispatcher;

public ContactPickerPage()
{
    this.InitializeComponent();
    ContactList.ItemsSource = contactSet;
    ContactList.SelectionChanged += ContactList_SelectionChanged;
}

protected override void OnNavigatedTo(NavigationEventArgs e)
{
    contactPickerUI.ContactRemoved += contactPickerUI_ContactRemoved;
}

protected override void OnNavigatedFrom(NavigationEventArgs e)
{
    contactPickerUI.ContactRemoved -= contactPickerUI_ContactRemoved;
}

async void contactPickerUI_ContactRemoved(ContactPickerUI sender, ContactRemovedEventArgs args)
{
    // The event handler may be invoked on a background thread, so use the Dispatcher to run the UI-related code on the UI thread.
    string removedId = args.Id;
    await dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
    {
        foreach (SampleContact contact in ContactList.SelectedItems)
        {
            if (contact.Id == removedId)
            {
                ContactList.SelectedItems.Remove(contact);
                OutputText.Text += "\n" + contact.DisplayName + " was removed from the basket";
                break;
            }
        }
    });
}

Questo codice di esempio mostra come aggiungere un contatto al carrello con il metodo AddContact(Contact).

switch (contactPickerUI.AddContact(contact))
{
    case AddContactResult.Added:
        // Notify the user that the contact was added
        OutputText.Text = contact.DisplayName + " was added to the basket";
        break;
    case AddContactResult.AlreadyAdded:
        // Notify the user that the contact is already added
        OutputText.Text = contact.DisplayName + " is already in the basket";
        break;
    case AddContactResult.Unavailable:
    default:
        // Notify the user that the basket is unavailable
        OutputText.Text = contact.DisplayName + " could not be added to the basket";
        break;
}

Questo codice di esempio illustra come rimuovere un contatto dal carrello e rispondere alla rimozione.

foreach (SampleContact removed in e.RemovedItems)
{
    if (contactPickerUI.ContainsContact(removed.Id))
    {
        contactPickerUI.RemoveContact(removed.Id);
        OutputText.Text = removed.DisplayName + " was removed from the basket";
    }
}
