Examples

This example demonstrates how to display AppointmentEditPage to edit general appointment, pattern, occurrence, or to add a new appointment when users taps on the scheduler:

const string EditPatternAction = "Edit pattern";
const string EditOccurrenceAction = "Edit occurrence";
const string EditNormalAction = "Edit";

async void Handle_OnTap(object sender, SchedulerGestureEventArgs e) {
    if (e.AppointmentInfo != null) {
        string selectedAction = await DisplaySelectAppointmentEditActionSheet(e.AppointmentInfo.Appointment);
        switch (selectedAction) {
            case EditPatternAction:
                PushEditAppointmentPage(scheduler.GetPattern(e.AppointmentInfo.Appointment));
                break;
            case EditOccurrenceAction:
            case EditNormalAction:
                PushEditAppointmentPage(e.AppointmentInfo.Appointment);
                break;
            default:
                break;
        }
    } else {
        if (e.IntervalInfo != null) { PushNewAppointmentPage(e.IntervalInfo); }
    }
}

async void PushEditAppointmentPage(AppointmentItem target) {
    var page = new AppointmentEditPage(scheduler, target);
    await Navigation.PushAsync(page);
}
async void PushNewAppointmentPage(IntervalInfo info) {
    var page = new AppointmentEditPage(scheduler, info.Start, info.End, info.AllDay);
    await Navigation.PushAsync(page);
}

async Task<String> DisplaySelectAppointmentEditActionSheet(AppointmentItem target) {
    string[] actions = null;
    string deleteAction = null;
    switch (target.Type) {
        case AppointmentType.Normal:
            actions = new string[] { EditNormalAction };
            break;
        default:
            actions = new string[] { EditPatternAction, EditOccurrenceAction };
            break;
    }
    return await this.DisplayActionSheet(null, "Cancel", null, actions);
}
