[alfredo zuloaga]

When update an appoinment that already exists neither the color, subject or programming was updated this 
also didnt work with any custom object using MVVM pattern.

The Refresh method don't exists for SfSchedule in Xamarin.Forms V.15.3.0.29




XAML
<syncfusion:SfSchedule x:Name="schedule" ScheduleView="MonthView" ShowAppointmentsInline="True"  >
<Button Text="Update" Clicked="Button_Update" />


//Instance variable
// Creating an instance for schedule appointment collection
ObservableCollection<ScheduleAppointment> scheduleAppointmentCollection = new ObservableCollection<ScheduleAppointment>();


...
In constructor of class
after   call InitializeComponent();


        
    //Adding schedule appointment in schedule appointment collection 
        var scheduleAppointment = new ScheduleAppointment()
        {
        	StartTime = new DateTime(2017, 05, 08, 10, 0, 0),
        	EndTime = new DateTime(2017, 05, 08, 12, 0, 0),
        	Subject = "Occurs every alternate day",
        	IsRecursive = true
        };

    //Adding schedule appointment in schedule appointment collection
        scheduleAppointmentCollection.Add(scheduleAppointment);

    //Adding schedule appointment collection to DataSource of SfSchedule
        schedule.DataSource=scheduleAppointmentCollection; 

    // Creating recurrence rule
        RecurrenceProperties recurrenceProperties = new RecurrenceProperties();
        recurrenceProperties.RecurrenceType = RecurrenceType.Daily;
        recurrenceProperties.IsRangeRecurrenceCount = true;
        recurrenceProperties.DailyNDays = 2;
        recurrenceProperties.IsDailyEveryNDays = true;
        recurrenceProperties.IsWeeklySunday = false;
        recurrenceProperties.IsWeeklyMonday = true;
        recurrenceProperties.IsWeeklyTuesday = false;
        recurrenceProperties.IsWeeklyWednesday = false;
        recurrenceProperties.IsWeeklyThursday = false;
        recurrenceProperties.IsWeeklyFriday = false;
        recurrenceProperties.IsWeeklySaturday = false;
        recurrenceProperties.RangeRecurrenceCount = 10;
        recurrenceProperties.RecurrenceRule = DependencyService.Get<IRecurrenceBuilder>().RRuleGenerator(recurrenceProperties, scheduleAppointment.StartTime, scheduleAppointment.EndTime);

    // Setting recurrence rule to schedule appointment
        scheduleAppointment.RecurrenceRule = recurrenceProperties.RecurrenceRule;

....
...


//IN CLICK EVENT

 private void Button_Update(object sender, EventArgs e)
        {

var scheduleAppointment =scheduleAppointmentCollection[0];


RecurrenceProperties recurrenceProperties = new RecurrenceProperties();
        recurrenceProperties.RecurrenceType = RecurrenceType.Daily;
        recurrenceProperties.IsRangeRecurrenceCount = true;
        recurrenceProperties.DailyNDays = 2;
        recurrenceProperties.IsDailyEveryNDays = true;
        recurrenceProperties.IsWeeklySunday = false;
        recurrenceProperties.IsWeeklyMonday = true;
        recurrenceProperties.IsWeeklyTuesday = false;
        recurrenceProperties.IsWeeklyWednesday = false;
        recurrenceProperties.IsWeeklyThursday = false;
        recurrenceProperties.IsWeeklyFriday = false;
        recurrenceProperties.IsWeeklySaturday = false;
        recurrenceProperties.RangeRecurrenceCount = 40; // HERE IS THE NEW VALUE
        recurrenceProperties.RecurrenceRule = DependencyService.Get<IRecurrenceBuilder>().RRuleGenerator(recurrenceProperties, scheduleAppointment.StartTime, scheduleAppointment.EndTime);

    // Setting recurrence rule to schedule appointment
        scheduleAppointment.RecurrenceRule = recurrenceProperties.RecurrenceRule;

        scheduleAppointment.Subject="I Expect the change";
}
