Gerenciar compromissos
Pelo namespace Windows.ApplicationModel.Appointments, você pode criar e gerenciar compromissos no aplicativo de calendário de um usuário. Aqui, mostraremos como criar um compromisso, adicioná-lo a um aplicativo de calendário, substituí-lo no aplicativo de calendário e depois removê-lo desse aplicativo de calendário. Também mostraremos como exibir um intervalo de tempo para um aplicativo de calendário e criar um objeto de recorrência de compromisso.
Criar um compromisso e aplicar dados a ele
Crie um objeto Windows.ApplicationModel.Appointments.Appointment e atribua-o a uma variável. Em seguida, aplique ao Compromisso as propriedades de compromisso que foram fornecidas por meio da interface do usuário por um usuário.

Adicionar um compromisso ao calendário do usuário
Crie um objeto Windows.ApplicationModel.Appointments.Appointment e atribua-o a uma variável. Em seguida, chame o método AppointmentManager.ShowAddAppointmentAsync(Appointment, Rect, Placement) para mostrar a interface do usuário de compromisso de adição do provedor de compromissos padrão, para permitir que o usuário adicione um compromisso. Se o usuário clicou em Adicionar, o exemplo imprimirá o identificador de compromisso retornado por 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.";
}
}
Observação Para aplicativos da Loja do Windows Phone, ShowAddAppointment funciona exatamente como ShowEditNewAppointment, pois a caixa de diálogo exibida para adicionar o compromisso é editável.
Substituir um compromisso no calendário do usuário
Crie um objeto Windows.ApplicationModel.Appointments.Appointment e atribua-o a uma variável. Em seguida, chame o método AppointmentManager.ShowReplaceAppointmentAsync apropriado para mostrar a interface do usuário de substituição de compromisso do provedor de compromissos padrão para permitir que o usuário substitua um compromisso. O usuário também fornece o identificador de compromisso que deseja substituir. Esse identificador foi retornado de AppointmentManager.ShowAddAppointmentAsync. Se o usuário clicou em Substituir, o exemplo imprimirá que ele atualizou esse identificador de compromisso.
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.";
}
}
}
Remover um compromisso do calendário do usuário
Chame o método AppointmentManager.ShowRemoveAppointmentAsync apropriado para mostrar a interface do usuário de remoção de compromisso do provedor de compromissos padrão, para permitir que o usuário remova um compromisso. O usuário também fornece o identificador de compromisso que deseja remover. Esse identificador foi retornado de AppointmentManager.ShowAddAppointmentAsync. Se o usuário clicou em Excluir, o exemplo imprimirá que ele removeu o compromisso especificado por esse identificador de compromisso.
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";
}
}
}
Mostrar um período de tempo para o provedor de compromissos
Chame o método AppointmentManager.ShowTimeFrameAsync para mostrar um intervalo de tempo específico para a interface do usuário principal do provedor de compromissos padrão se o usuário clicou em Mostrar. O exemplo imprime que o provedor de compromissos padrão apareceu na tela.
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.";
}
Criar um objeto de recorrência de compromisso e aplicar dados a ele
Crie um objeto Windows.ApplicationModel.Appointments.AppointmentRecurrence e atribua-o a uma variável. Em seguida, aplique ao AppointmentRecurrence as propriedades de recorrência que foram fornecidas por meio da interface do usuário por um usuário.
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.";
}
}
Adicionar um novo compromisso editável
ShowEditNewAppointmentAsync funciona exatamente como ShowAddAppointmentAsync , exceto que a caixa de diálogo para adicionar o compromisso é editável para que o usuário possa modificar os dados do compromisso antes de salvá-los.
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.";
}
}
Mostrar detalhes do compromisso
ShowAppointmentDetailsAsync faz com que o sistema mostre detalhes do compromisso especificado. Um aplicativo que implementa calendários de aplicativos pode optar por ser ativado para mostrar detalhes de compromissos em calendários que possui. Caso contrário, o sistema mostrará os detalhes do compromisso. Uma sobrecarga do método que aceita um argumento de data de início é fornecida para mostrar detalhes de uma instância de um compromisso recorrente.
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);
}
}
