System.ArgumentOutOfRangeException: Year, Month, and Day parameters describe an un-representable DateTime.

This issue happens when using DayView, MultiDayView, Month view modes and when scrolling through the calendar to change the selected date. 

The issue happens on specific devices with android 14, Pixel 7, Galaxy S22. 

Workaround: 
Setting the time zone in calendar renderer to the DayView timelabelformat

public override bool TrySetViewMode(CalendarViewMode view, bool isAnimated)
        {
            if (view == CalendarViewMode.Day)
            {
                Control.DayView.DayEventsViewStyle.TimeLabelFormat.TimeZone = Java.Util.TimeZone.GetTimeZone("add time zone here");
            }

            return base.TrySetViewMode(view, isAnimated);
        }

Programmatically setting the DisplayDate property of the control doesn't update the UI (just shows the same date/appointments)

 

E.g.   Calendar.DisplayDate = Calendar.DisplayDate.AddMonths(2);

 

This worked in version 2020.1.114.1, but after updating the controls this no longer works.

I have added a TitleCellStyle to the calendar control.

<input:RadCalendar.TitleCellStyle>
    <input:CalendarCellStyle HorizontalTextAlignment="Center" VerticalTextAlignment="Center" BackgroundColor="LightGray" FontAttributes="Bold"/>
</input:RadCalendar.TitleCellStyle>

Then navigate from MonthView to DayView. The Title Text is not updated. It shows the text from the month view

For example, the TitleText in MonthView is January 2021, in the DayView should be the date the month and the year, 13 January 2021, but it displays January 2021

MonthView Title Text:

DayView Title Text

The calendar.ViewMode property isn't updated properly at least in these two scenarios:


Going to the Year view  mode by tapping the title (month name) when in Month view mode.
Going to the Day view mode by tapping a cell (day name) when in Month view mode.

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

Default calendar:

<telerikInput:RadCalendar x:Name="calendar"/>

 

 

Setting some styles (copied from https://docs.telerik.com/devtools/xamarin/controls/calendar/styling/calendar-styling-cell) :

<telerikInput:RadCalendar x:Name="calendar">
    <telerikInput:RadCalendar.TitleCellStyle>
        <telerikInput:CalendarCellStyle BackgroundColor="LightBlue" 
            TextColor="Gray" 
            FontSize="20"/>
        </telerikInput:RadCalendar.TitleCellStyle>
    <telerikInput:RadCalendar.DayNameCellStyle>
        <telerikInput:CalendarCellStyle TextColor="Black"/>
    </telerikInput:RadCalendar.DayNameCellStyle>
</telerikInput:RadCalendar>

 

 

 The month name loses current culture localization once the cell is styled.

Java.Lang.IllegalArgumentException:** 'Comparison method violates its general contract! is thrown when appointment source loads

For example, there are 33 appointments with the same start date and end date and 3 with a different start date and same end date as the other 33 appointments, all appointments are AllDay.
The exception is thrown on Android when loading the appointment source. It works fine on iOS and UWP.

Maybe I am over looking something, but I am unable to show the RadCalendar in the Agenda view mode with a dark background color. I have tried setting the background color of the RadCalendar to a dark color and the AgendaViewSettings only seem to allow me to set text colors and not the background. 

We use the control in three modes, DayView, MonthView and AgendaView and only in agenda we can't seem to change the background color.

Release 2020.3.1106 (R3 2020 minor release)

The background color for appointments is no longer visible in agenda view on iOS (Property "Color" on Appointment). The color works on both Day, Month and Week views, but not Agenda view. But it works on Android. It's only on iOS there is no background color. This worked before the latest update (Release R3 2020, Version 2020.3.916.1).

Is there anything else that needs to be done, except setting the Color property of appointments?

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
