We cannot reproduce the problem with the latest 2.05.39 version. I have created the Form1 instance with the SqlConnection object, then Form2 was created as an instance of the Form2 class inherited from Form1. As a result, Form Designer of Form2 contained the instance of SqlConnection inherited from the base form. There were no errors.

Please try the 2.05.39 version. If the problem persists, please provide us the steps we should follow to reproduce the issue. A test project will be appreciated.

I have tried DevExpress RibbonForm v9.1 (9.1.5.0) and performed the steps mentioned in my post above. There were no errors. Please provide us with the exact steps to reproduce the problem. Does this problem persist in different environment?
