1.Start a swipe gesture to the right (as like when you navigate to next three days) but stop it by return your finger back (holding the finger on the screen);
2. Since the gesture was canceled, you stay at 15th to 17th of July;
3.. Tap on some event to open it on other screen. Then come back to the calendar;
4.. Now you see other dates on the calendar, less than before, somewhat like 11th to 14th or 8th to 10th. Each time when you open other screen, calendar changes its displayed date. To cancel this behavior do new navigation swipe gesture.

Workaround:  get the DisplayDate before the navigation and set it when navigating back

If you try to explicitly set the Locale property of the native CalendarView through a custom renderer, the change is not applied in AgendaView ( the same works properly in other views).

While in DayView (or any other appropriate view), allow for appointments to be draggable to another time slot for rescheduling. 

When the calendar is in DayView mode and you tap on the 3rd of November, it incorrectly scrolls you back to the 27th of October. Another issue appears if you are on the 2nd and you try to swipe to the 3rd (by swiping the day area) - it does not allow you to do so.

On Android,  when the user selects a date on CalendarViewMode.Month mode, the DisplayDateChanged event is fired twice and the displayed date in CalendarViewMode.Day is incorrect. 

Sometimes the display date is 4-6 months ahead/behind or just with one month.

If Calendar TitleCellStyle and DisplayDate are set, control shows the title as current month ..not the month of the display date.

If the TimelineInterval property of the DayViewSettings is set to 1 hour, and the DayEndTime is, for example, "18.30", the last 30 minutes are not visualized in the Calendar View.

appointment color is not coming for ALL Day event in day or multi-day view.

Solution:

Use AppointmentTemplate https://docs.telerik.com/devtools/xamarin/controls/calendar/calendar-appointments#appointment-template

While testing our app around timezones, we found a case where the cell selection would not render if timezone was set to Portugal, Azores (GMT+00:00). Selector reappears after switching to another month though. For some weird reason we were not able to replicate this issue for a similar timezone like Casablanca, Morocco (GMT+00:00).

If you have an appointment with duration 15 min, it is not properly rendered in DayView/MultiDayView on Android - it is visualized as a 30 min appointment

When the Start and EndDate properties are changed one after another and each of them calls PropertyChanged the appointment does not render accurately. If for example there is an appointment from 3 PM to 4 PM (duration 1 hour) and the Appointment is changed to one hour earlier (from 2 PM to 3 PM) on the screen the Appointment is displayed from 2 PM to 4 PM (duration 2 hours).

Add support for pull to refresh gesture. 

When change my calendar view to Agenda, appointments with too large Title, overlap the time section in the container box.

Currently the first label marking the DayStartTime is not visualized in the timeline of the DayView (and MultiDayView) on Android. This leads to inconsistency with iOS, where the first label is displayed.

Xamarin Forms, Newest everything

Out of the box, all Calendar views for iOS are in AM/PM

In Android the MultiDay is 24 hour, but the Day view is AM/PM

How can I force Android MultiDay to be AM/PM ?

 

 

How can I hide week and month headers in Agenda View Mode?

Add a View that displays a list of the scheduled appointments.

When RadCalendar is used in Xamarin.Forms Shell project, the vertical scrolling is not possible.

Region.Op.REPLACE is deprecated and therefore the exception is thrown:

Provide events raised when a new appointment is created and when an existing appointment is updated/deleted.
