We have a RadCalendar and we set the CalendarViewMode to "Year". And we tap on an arbitrary month in order to open it (change the ViewMode to "Month").


EXPECTED result: The selected (tapped) month is opened, i.e. the ViewMode is changed to "Month". And this is happening on Android.

ACTUAL result: On iOS the result is this exception:
System.InvalidCastException: Unable to cast object of type 'TelerikUI.TKCalendarYearPresenter' to type 'UIKit.UIView'

We are only using the Rad ListView, so have only needed the Lite package but it requires the SkiaSharp package as well. It seems that Map, ImageEditor, PdfViewer and DataGrid controls are added in the lite nuget package.

There are 2 approaches to customize the theme -> directly override the resources in the BlueResources dictionary or create a custom resource dictionary and merge it instead of the BlueResources one.

If you take the first approach in a .NET standard project and override one of the colors -> an ArgumentException is thrown:

Use the second approach as a workaround where you create a custom resource dictionary, copy all the colors from the original one and modify them within your custom one.

Available in the R3 2018 SP release.

The reason for the exception is that when the IsBusy of the indicator changes, the Content is added to and removed from the visual tree. Because it is data-bound, the chart immediately tries to notify its native counterpart that an update is necessary, and the iOS control is looked up. However, sometimes, the old iOS control is found, which has been disposed.
A possible workaround is not to put content inside the busy indicator. Use the busy indicator as a simple overlay.

Available in the R3 2018 SP release.
