Bug Report
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);
}

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 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).

It would be handy to enable dates/disable dates based on an array of dates.
I have a situation where drivers are scheduled jobs that may exclude days within a 3-week period. Currently I can only select set the minimum and maximum dates for this period which allows them to select dates where no work is scheduled. Consequently my code must check if the selected date "is valid" before allowing displaying the jobs for the selected date.
Obviously it would be far easier if those dates were never enabled in the first place.

Hi,
I have been using Telerik controls for the last 4 years in WPF. One of the controls widely used is the RadScheduleView in which I manage customer appointments in hair dresser salons. Recently I tried to implement the same functionality on Mobile Apps using Xamarin.
Some of the appointments generated by users contain overlapping times since they are serviced by different employees. This functionality in WPF is managed perfectly using RadScheduleView. Now I am using the same data by downloading it into a MobileApp (for now Android App) and reproducing similar appointments but on RadCalendar. Every time an appointment have overlaps, the way system is recreating it on the calendar is misleading and sometimes appointments are also hidden.
The following is a Code snippet that also produce the same results.
Steps to reproduce:
1. Appointment View module that inherits from Telerik.XamarinForms.Input.Appointment and add additional properties to manage appointments:
public class AppointmentViewModel : Telerik.XamarinForms.Input.Appointment
{
public Int32 PK { get; set; } = -1;
public String DisplayStartTime
{
get
{
return StartDate.ToString("HH:mm");
}
}
public String DisplayEndTime
{
get
{
return EndDate.ToString("HH:mm");
}
}
public double AppointmentDate
{
get
{
return StartDate.Date.ToOADate();
}
}
public string AppointmentDisplayDate
{
get
{
return StartDate.Date.ToString("ddd dd MMM");
}
}
}Note: To render appointments, I am still using default properties of the class Telerik.XamarinForms.Input.Appointment, see point 3.
2. Create Page (XAML) with calendar and a refresh button:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"

4. After running the above code, the following issues are encountered when appointments are generated on the calendar (screens taken from original application):
- Customer_8.jpg - Appointment for Customer 8 is overlapping appointment with customer 7 when on calendar there is enough space in the other columns;
- Customer_14.jpg - Appointment for Customer 14 is overlapping appointment with customer 12. Appointment for Customer 13 is hidden under Customer 14;
- Customers_26_27_28.jpg - Appointments for Customers 26,27,28 are overlapping with appointment for customer 24 when on calendar their is ample space were to generate these appoints.
- Customer_32.jpg - This is the worst scenario. Appointments for Customer 32 and 33 are sharing the same time slot. This appointments overlapping and users can only view appointment 33.
Can you please give me an indication what I am doing wrong in my code or how can avoid such cases. The scenarios indicated above are misleading to the final users. I notised that such tickets for similar issues where raised since 2017 but never finally answered.
