Hello Telerik Team,
I would like to report a bug I found on Android (not iOS).
If you use a RadCalendar inside a content page which is inside a TabbedPage, you can't swipe on the RadCalendar when it is in ViewMode=Week.
You have to draw a diagonal to make it works otherwise, the swipe (on the RadCalendar) is handled by the TabbedPage and it changes the current page being displayed.
If the RadCalendar ViewMode is set in MultiDay, the Swipe is well handled by the RadCalendar (instead of the TabbedPage).
Expected behavior : swiping on the RadCalendar in ViewMode=Week should change the displayed week (like it does in ViewMode=MultiDay).
Current Behavior : swiping on the RadCalendar in ViewMode=Week should change the selected page of the TabbedPage.
Why I think it is a bug : in ViewMode=MultiDay, the swipe isn't handled the same way : it actually change the displayed day and doesn't change the current page of the TabbedPage control.
PS : if the RadCalendar ViewMode is set to Month, the swipe to change the displayed month is from top to bottom or bottom to top unlike the Week mode which handle swipe from right to left or left to right.
I wish you a happy new year and a lot of bug fix with a lot of new feature released :)
Hi,
The finnish translations are not correct in the calendar component. We would like to change the translations for names of days and month, in the calendar component. As far as we know, this is not possible. We can only change 4 texts (4 calendar views localization keys) according to this documentation: https://docs.telerik.com/devtools/xamarin/controls/calendar/calendar-localization
Localization works, and we can set the language. But for the finnish language, the translations you provide for days and months are not correct. We would like to be able to change these texts ourselves, name of days and months. Is there any way for us to do this? We need the Finnish translations to be correct.
Thank you!
Best Regards,
Joakim

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:

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.
