[CLOSED] DirectEvent throwing error for controls creating at runtime
Hi,
I have created controls at runtime and adding DirectEvent to those controls. while running the form the error throwing like control not found. I am able to access those controls with DirectMethod, but it is not possible in all scenarios. So I need to resolve issue with DirectEvent. Please check the following code
