Gestire gli appuntamenti
Attraverso lo spazio dei nomi Windows.ApplicationModel.Appointments è possibile creare e gestire appuntamenti nell'app calendario di un utente. Qui viene mostrato come creare un appuntamento, aggiungerlo a un'app calendario, sostituirlo nell'app calendario e rimuoverlo dall'app calendario. Verrà inoltre mostrato come visualizzare un intervallo di tempo per un'applicazione calendario e come creare un oggetto appuntamento-ricorrenza.
Creare un appuntamento e applicarvi dati
Creare un oggetto Windows.ApplicationModel.Appointments.Appointment e assegnarlo a una variabile. Applicare quindi ad Appointment le proprietà dell'appuntamento fornite tramite l'interfaccia da un utente.

Aggiungere un appuntamento al calendario dell'utente
Creare un oggetto Windows.ApplicationModel.Appointments.Appointment e assegnarlo a una variabile. Chiamare quindi il metodo AppointmentManager.ShowAddAppointmentAsync(Appointment, Rect, Placement) per visualizzare l'interfaccia utente del componente aggiuntivo del provider di appuntamenti predefinita, per consentire all'utente di aggiungere un appuntamento. Se l'utente ha fatto clic su Aggiungi, nell'esempio viene stampato l'identificatore dell'appuntamento restituito da ShowAddAppointmentAsync.
private async void Add-Click(object sender, RoutedEventArgs e)
{
// Create an Appointment that should be added the user's appointments provider app.
var appointment = new Windows.ApplicationModel.Appointments.Appointment();
// Get the selection rect of the button pressed to add this appointment
var rect = GetElementRect(sender as FrameworkElement);
// ShowAddAppointmentAsync returns an appointment id if the appointment given was added to the user's calendar.
// This value should be stored in app data and roamed so that the appointment can be replaced or removed in the future.
// An empty string return value indicates that the user canceled the operation before the appointment was added.
String appointmentId = await Windows.ApplicationModel.Appointments.AppointmentManager.ShowAddAppointmentAsync(
appointment, rect, Windows.UI.Popups.Placement.Default);
if (appointmentId != String.Empty)
{
ResultTextBlock.Text = "Appointment Id: " + appointmentId;
}
else
{
ResultTextBlock.Text = "Appointment not added.";
}
}
Nota Per le app del Windows Phone Store, ShowAddAppointment funziona esattamente come ShowEditNewAppointment in quanto la finestra di dialogo visualizzata per l'aggiunta dell'appuntamento è modificabile.
Sostituire un appuntamento nel calendario dell'utente
Creare un oggetto Windows.ApplicationModel.Appointments.Appointment e assegnarlo a una variabile. Chiamare quindi il metodo AppointmentManager.ShowReplaceAppointmentAsync appropriato per visualizzare l'interfaccia utente di sostituzione appuntamento del provider di appuntamenti predefinito per consentire all'utente di sostituire un appuntamento. L'utente fornisce anche l'identificatore di appuntamento che desidera sostituire. Questo identificatore è stato restituito da AppointmentManager.ShowAddAppointmentAsync. Se l'utente ha fatto clic su Sostituisci, l'esempio stampa l'identificatore dell'appuntamento aggiornato.
private async void Replace-Click(object sender, RoutedEventArgs e)
{
// The appointment id argument for ReplaceAppointmentAsync is typically retrieved from AddAppointmentAsync and stored in app data.
String appointmentIdOfAppointmentToReplace = AppointmentIdTextBox.Text;
if (String.IsNullOrEmpty(appointmentIdOfAppointmentToReplace))
{
ResultTextBlock.Text = "The appointment id cannot be empty";
}
else
{
// The Appointment argument for ReplaceAppointmentAsync should contain all of the Appointment' s properties including those that may have changed.
var appointment = new Windows.ApplicationModel.Appointments.Appointment();
// Get the selection rect of the button pressed to replace this appointment
var rect = GetElementRect(sender as FrameworkElement);
// ReplaceAppointmentAsync returns an updated appointment id when the appointment was successfully replaced.
// The updated id may or may not be the same as the original one retrieved from AddAppointmentAsync.
// An optional instance start time can be provided to indicate that a specific instance on that date should be replaced
// in the case of a recurring appointment.
// If the appointment id returned is an empty string, that indicates that the appointment was not replaced.
String updatedAppointmentId;
if (InstanceStartDateCheckBox.IsChecked.Value)
{
// Replace a specific instance starting on the date provided.
var instanceStartDate = InstanceStartDateDatePicker.Date;
updatedAppointmentId = await Windows.ApplicationModel.Appointments.AppointmentManager.ShowReplaceAppointmentAsync(
appointmentIdOfAppointmentToReplace, appointment, rect, Windows.UI.Popups.Placement.Default, instanceStartDate);
}
else
{
// Replace an appointment that occurs only once or in the case of a recurring appointment, replace the entire series.
updatedAppointmentId = await Windows.ApplicationModel.Appointments.AppointmentManager.ShowReplaceAppointmentAsync(
appointmentIdOfAppointmentToReplace, appointment, rect, Windows.UI.Popups.Placement.Default);
}
if (updatedAppointmentId != String.Empty)
{
ResultTextBlock.Text = "Updated Appointment Id: " + updatedAppointmentId;
}
else
{
ResultTextBlock.Text = "Appointment not replaced.";
}
}
}
Rimuovere un appuntamento dal calendario dell'utente
Chiamare il metodo AppointmentManager.ShowRemoveAppointmentAsync appropriato per visualizzare l'interfaccia utente di rimozione appuntamento del provider di appuntamenti predefinito per consentire all'utente di sostituire un appuntamento. L'utente fornisce anche l'identificatore di appuntamento che desidera rimuovere. Questo identificatore è stato restituito da AppointmentManager.ShowAddAppointmentAsync. Se l'utente ha fatto clic su Elimina, l'esempio stampa che ha rimosso l'appuntamento specificato dall'identificatore dell'appuntamento.
private async void Remove-Click(object sender, RoutedEventArgs e)
{
// The appointment id argument for ShowRemoveAppointmentAsync is typically retrieved from AddAppointmentAsync and stored in app data.
String appointmentId = AppointmentIdTextBox.Text;
// The appointment id cannot be null or empty.
if (String.IsNullOrEmpty(appointmentId))
{
ResultTextBlock.Text = "The appointment id cannot be empty";
}
else
{
// Get the selection rect of the button pressed to remove this appointment
var rect = GetElementRect(sender as FrameworkElement);
// ShowRemoveAppointmentAsync returns a boolean indicating whether or not the appointment related to the appointment id given was removed.
// An optional instance start time can be provided to indicate that a specific instance on that date should be removed
// in the case of a recurring appointment.
bool removed;
if (InstanceStartDateCheckBox.IsChecked.Value)
{
// Remove a specific instance starting on the date provided.
var instanceStartDate = InstanceStartDateDatePicker.Date;
removed = await Windows.ApplicationModel.Appointments.AppointmentManager.ShowRemoveAppointmentAsync(
appointmentId, rect, Windows.UI.Popups.Placement.Default, instanceStartDate);
}
else
{
// Remove an appointment that occurs only once or in the case of a recurring appointment, replace the entire series.
removed = await Windows.ApplicationModel.Appointments.AppointmentManager.ShowRemoveAppointmentAsync(
appointmentId, rect, Windows.UI.Popups.Placement.Default);
}
if (removed)
{
ResultTextBlock.Text = "Appointment removed";
}
else
{
ResultTextBlock.Text = "Appointment not removed";
}
}
}
Mostra un intervallo di tempo per il provider di appuntamenti
Chiamare il metodo AppointmentManager.ShowTimeFrameAsync per visualizzare un intervallo di tempo specifico per l'interfaccia utente primaria del provider di appuntamenti predefinito se l'utente ha fatto clic su Mostra. L'esempio stampa che il provider di appuntamenti predefinito è apparso sullo schermo.
private async void Show-Click(object sender, RoutedEventArgs e)
{
var dateToShow = new DateTimeOffset(2015, 6, 12, 18, 32, 0, 0, TimeSpan.FromHours(-8));
var duration = TimeSpan.FromHours(1);
await Windows.ApplicationModel.Appointments.AppointmentManager.ShowTimeFrameAsync(dateToShow, duration);
ResultTextBlock.Text = "The default appointments provider should have appeared on screen.";
}
Creare un oggetto di ricorrenza appuntamento e applicarvi dati
Creare un oggetto Windows.ApplicationModel.Appointments.AppointmentRecurrence e assegnarlo a una variabile. Applicare quindi ad AppointmentRecurrence le proprietà di ricorrenza fornite tramite l'interfaccia da un utente.
private void Create-Click(object sender, RoutedEventArgs e)
{
bool isRecurrenceValid = true;
var recurrence = new Windows.ApplicationModel.Appointments.AppointmentRecurrence();
// Unit
switch (UnitComboBox.SelectedIndex)
{
case 0:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Daily;
break;
case 1:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Weekly;
break;
case 2:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Monthly;
break;
case 3:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.MonthlyOnDay;
break;
case 4:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Yearly;
break;
case 5:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.YearlyOnDay;
break;
}
// Occurrences
// Note: Occurrences and Until properties are mutually exclusive.
if (OccurrencesRadioButton.IsChecked.Value)
{
recurrence.Occurrences = (uint)OccurrencesSlider.Value;
}
// Until
// Note: Until and Occurrences properties are mutually exclusive.
if (UntilRadioButton.IsChecked.Value)
{
recurrence.Until = UntilDatePicker.Date;
}
// Interval
recurrence.Interval = (uint)IntervalSlider.Value;
// Week of the month
switch (WeekOfMonthComboBox.SelectedIndex)
{
case 0:
recurrence.WeekOfMonth = Windows.ApplicationModel.Appointments.AppointmentWeekOfMonth.First;
break;
case 1:
recurrence.WeekOfMonth = Windows.ApplicationModel.Appointments.AppointmentWeekOfMonth.Second;
break;
case 2:
recurrence.WeekOfMonth = Windows.ApplicationModel.Appointments.AppointmentWeekOfMonth.Third;
break;
case 3:
recurrence.WeekOfMonth = Windows.ApplicationModel.Appointments.AppointmentWeekOfMonth.Fourth;
break;
case 4:
recurrence.WeekOfMonth = Windows.ApplicationModel.Appointments.AppointmentWeekOfMonth.Last;
break;
}
// Days of the Week
// Note: For Weekly, MonthlyOnDay or YearlyOnDay recurrence unit values, at least one day must be specified.
if (SundayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Sunday; }
if (MondayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Monday; }
if (TuesdayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Tuesday; }
if (WednesdayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Wednesday; }
if (ThursdayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Thursday; }
if (FridayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Friday; }
if (SaturdayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Saturday; }
if (((recurrence.Unit == Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Weekly) ||
(recurrence.Unit == Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.MonthlyOnDay) ||
(recurrence.Unit == Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.YearlyOnDay)) &&
(recurrence.DaysOfWeek == Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.None))
{
isRecurrenceValid = false;
ResultTextBlock.Text = "The recurrence specified is invalid. For Weekly, MonthlyOnDay or YearlyOnDay recurrence unit values, " +
"at least one day must be specified.";
}
// Month of the year
recurrence.Month = (uint)MonthSlider.Value;
// Day of the month
recurrence.Day = (uint)DaySlider.Value;
if (isRecurrenceValid)
{
ResultTextBlock.Text = "The recurrence specified was created successfully and is valid.";
}
}
Aggiungere un nuovo appuntamento modificabile
ShowEditNewAppointmentAsync funziona esattamente come ShowAddAppointmentAsync, a eccezione del fatto che la finestra di dialogo per l'aggiunta dell'appuntamento è modificabile in modo che l'utente possa modificare i dati dell'appuntamento prima di salvarli.
private async void AddAndEdit-Click(object sender, RoutedEventArgs e)
{
// Create an Appointment that should be added the user' s appointments provider app.
var appointment = new Windows.ApplicationModel.Appointments.Appointment();
appointment.StartTime = DateTime.Now + TimeSpan.FromDays(1);
appointment.Duration = TimeSpan.FromHours(1);
appointment.Location = "Meeting location";
appointment.Subject = "Meeting subject";
appointment.Details = "Meeting description";
appointment.Reminder = TimeSpan.FromMinutes(15); // Remind me 15 minutes prior
// ShowAddAppointmentAsync returns an appointment id if the appointment given was added to the user' s calendar.
// This value should be stored in app data and roamed so that the appointment can be replaced or removed in the future.
// An empty string return value indicates that the user canceled the operation before the appointment was added.
String appointmentId =
await Windows.ApplicationModel.Appointments.AppointmentManager.ShowEditNewAppointmentAsync(appointment);
if (appointmentId != String.Empty)
{
ResultTextBlock.Text = "Appointment Id: " + appointmentId;
}
else
{
ResultTextBlock.Text = "Appointment not added.";
}
}
Mostrare i dettagli dell'appuntamento
ShowAppointmentDetailsAsync fa sì che il sistema mostri i dettagli per l'appuntamento specificato. Un'app che implementa i calendari dell'app può scegliere di essere attivata per visualizzare i dettagli per gli appuntamenti nei calendari di cui è proprietaria. In caso contrario, il sistema mostrerà i dettagli dell'appuntamento. Viene fornito un overload del metodo che accetta un argomento data di inizio per visualizzare i dettagli per un'istanza di un appuntamento ricorrente.
private async void ShowAppointmentDetails-Click(object sender, RoutedEventArgs e)
{
if (instanceStartTime == null)
{
await Windows.ApplicationModel.Appointments.AppointmentManager.ShowAppointmentDetailsAsync(
currentAppointment.LocalId);
}
else
{
// Specify a start time to show an instance of a recurring appointment
await Windows.ApplicationModel.Appointments.AppointmentManager.ShowAppointmentDetailsAsync(
currentAppointment.LocalId, instanceStartTime);
}
}
