@arivoir thanks for the report. I have tagged the issue so that the correct ends take a look.

viniciusjarina commented 5 years ago

Hi @arivoir what is the custom control your trying to load?

arivoir commented 5 years ago

Any of the GrapeCity controls I'm working on.

viniciusjarina commented 5 years ago

@arivoir can you give more details on how to use the GrapeCity controls? or create a step by step way to repro the issue? Thank you

arivoir commented 5 years ago

Sure, here are the steps

arivoir commented 5 years ago

Here there is the exception I got from the log file

Hello @arivoir thank you for the detailed report.

I've tested here with the latest version of VS4M. From the logs it seems the problem is on the C1.iOS.Grid component side.
