Hi all!
I have an event which triggers an async loading task in which I change data which is bound to the RadCalendar.
In my development environment I never had any issues but users on RDS-Server have. This is the stack-trace from there log:
ERROR2020-01-20 11:25:28 – Fatal Error - StackTrace: ModuleContainerManager - HandleUnhandledException

Do I have to take care some how of the binding or how can I catch this to prevent app crash?
Thanks for help!!!!!!

Hello Gert,
We are not aware of the reported behavior. Can you share some a additional information on the case? More specifically, code snippets (runnable if possible) showing how the RadCalendar is setup and how its selection is updated.
