    Have updated to the latest version of Telerik.Xamarin.iOS (2014.3.1326.0) to use in a Xamarin Unified API project.


    override TKCalendarEventProtocol[] EventsForDate (TKCalendar calendar, NSDate date)
            return new TKCalendarEventProtocol [] {
                new TKCalendarEventProtocol {
                    StartDate = date,
                    EndDate = date

    and get error

    Foundation.ModelNotImplementedException: Exception of type 'Foundation.ModelNotImplementedException' was thrown.
    at TelerikUI.TKCalendarEventProtocol.set_StartDate (Foundation.NSDate value)

    This worked fine before the upgrade to the latest Telerik. Please help?

    Hello, Martin, 

    Thank you for contacting us.

    TKCalendarEventProtocol is just an abstract interface describing an event in TKCalendar. Adopting this interface allows using custom business objects as data source for TKCalendar.  Its default implementation is TKCalendarEvent. You have two options when handling EventsForDate method. The first one is to replace TKCalendarEventProtocol with its default implementation - TKCalendarEvent. The second one is creating your own class which inherits from TKCalendarEventProtocol.

    I hope this helps, If you have any questions do not hesitate to contact us.
