Hi

As advised in Ticket 883426, I have cloned https://github.com/telerik/ios-sdk/tree/master/TelerikUIExamplesInCSharp. However, when I run the C# Calendar examples and I select "Calendar with events", I get the following exception:

System.InvalidCastException: Unable to cast object of type 'TelerikUI.TKCalendarPresenterWrapper' to type 'TelerikUI.TKCalendarMonthPresenter'.<br>  at Examples.CalendarWithEvents.ViewDidLoad () [0x00125] in <redacted>Telerik/ios-sdk/TelerikUIExamplesInCSharp/Examples/Calendar/CalendarWithEvents.cs:65<br>  at at (wrapper managed-to-native) MonoTouch.UIKit.UIApplication:UIApplicationMain (int,string[],intptr,intptr)<br>  at MonoTouch.UIKit.UIApplication.Main (System.String[] args, IntPtr principal, IntPtr delegate) [0x00005] in /Developer/MonoTouch/Source/monotouch/src/UIKit/UIApplication.cs:62<br>  at MonoTouch.UIKit.UIApplication.Main (System.String[] args, System.String principalClassName, System.String delegateClassName) [0x00038] in /Developer/MonoTouch/Source/monotouch/src/UIKit/UIApplication.cs:46<br>  at Examples.Application.Main (System.String[] args) [0x00008] in <redacted>Telerik/ios-sdk/TelerikUIExamplesInCSharp/Main.cs:17


 I am using version 2014.3.1022.0 of the Tekerik.Xamarin.iOS lib

Thanks

Hi Martin,

Thank you for contacting us.

I confirm the observed issue. We found that this issue appears because the latest release of mono touch changed the way how Objective-C protocols are handled. We are in contact with Xamarin representatives and we are investigating how to resolve the issue. 

Please note that the latest version of our Xamarin examples is located in xamarin-sdk repository. The ios-sdk repository will contain only native iOS SDK examples in future.

Should you have any other questions, we will be glad to help.

Regards,
Jack
