Add a property for setting the start day of the week.

Available in minor release 2018.1.0315. It will also be available in the R2 2018 release.

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 ?

 

 

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

SelectionChanged starts calling twice when appointments collection is changed at runtime from within the event.

The problem occurs when I update the Events property on either of the events DisplayDateChanged or SelectionChanged. It seems these events are triggered another time, sometimes, when the AppointmentSource gets refreshed. I say sometimes because you can navigate through the weeks as normal, but as some points you notice something went wrong. Here’s a list of what I have encountered so far :
When sliding through the weeks from the days header, let’s say the selected day is a Monday, the next weeks would have the Monday selected as expected. Then a random week would have an other selected day (Friday). It would happen randomly until some weeks get skipped completely.
When sliding through the weeks from the days header, let’s say the selected day is a Monday, the next weeks would have the Monday selected as expected. If I touch the Friday box,  the selected date gets initially updated  to Friday and then a random day between Monday and Friday gets selected.
When sliding through the weeks from the days header, the calendar gets stucked on a random week, and sliding forward or backward through the days header just put you back to the same week. In this case the only way to move to the next/previous week is to slide through the time slot.

The calendar does not scroll to the updated DisplayDate when MultiDayView is used and the DisplayDate is set in DisplayDateChanged event.

When RadCalendar is inside Xamarin Forms Tabbed Page. Switching between tabs triggers Calendar SelectionChanged and the calendar DisplayDate is changed. 

Workaround:
the issue could not be reproduced when RadTabView is used and its IsContentPreserved property is set to true.

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

As of the R3 2019 Release of Telerik UI for Xamarin, Day View and Multi-Day View are the only two views where Appointments can have custom data templates.
This is done via setting Appointment Content Template to a template selector in the Day view or Multi-Day view settings object.
It would be useful to add Appointment Content Templates to the Agenda View, allowing for finer customization of the appointment. 
Similar to Day View and Multi-Day View, it could be set via AgendaViewSettings.
Agenda view has differing functionality from Day and MultiDay view which makes it better suited to certain user experiences, however it is currently limited and missing the same appointment customization options that the day and multi-day views allow.

In the RadCalendar, if we set the DisplayDate to future date (For example, current date is 04-03-2024 and the display date as 08-April-2024), application gets crashed in iOS platform. This issue occurs only in iOS 17 and above versions.

Exception

NSInternalInconsistencyException Reason: UIGraphicsBeginImageContext() failed to allocate CGBitampContext: size={0, 0}

It would be nice to see the current displayed year in the Header while displaying the RadCalendar in 'MonthName' CalendarViewMode.

Will be good to have a property in the Calendar control for Xamrin Forms, to hide the columns in the calendar to show only business days.  The new property name could be:

HideWeekends or ShowWeekends or ShowOnlyBusinessDays.   The idea would be have the availabilty to display a calendar only for working days (Monday thu Friday).

Thanks

Currently, some days of the previous and next month are available when the Calendar is in MonthView. We can consider exposing a mechanism to show only the days from the current month as the TKCalendarViewMode.Flow mode in iOS(http://docs.telerik.com/devtools/ios/calendar/view-modes#flow-layout-with-months-and-month-days).

Hi!

I've tried your TKCalendar and it looks really good. But unfortunately, there is an issue on iOS(Xamarin). I set MaxDate = DateTime.Today and SelectionMode == Range. When I tap on date grater than today they don't selected, as expected. But when I select dates by drag gesture I can select every days in month.The worst thing is that it seems that there is no way to turn off drag selection on iOS in Range selection mode. I could provide you with any files if it's necessary.

In a scenario where you are trying to set the AppointmentsSource of the RadCalendar in the OnAppearing event of the Page, a NullReferenceException is thrown in the Telerik.XamarinForms.InputRenderer.WinRT.CalendarAdapter UpdateAppointmentsSource method.

A workaround is to make the OnAppearing method async and await the action that sets the AppointmentSource.

The more appointments you add to the AppointmentsSource, the poorer the performance of the Calendar is. 

This can be observed when switching months in month view. In case you have a huge amount of appointments, switching the months takes time. The issue is specifically obvious when a single month contains lots of appointments(600 for example). However, it is present when you are switching months that do not have any appointments at all as well.
