Want to see you is how to control closed?
FormB "closed", refers to the release of the Form object or remove pagecontrol page? Or is it just hide? Or call the Close? .

In addition, the "how to save in formA reminder or cancel the data in the fromB?"
- from the single responsibility principle consideration, this matter, should be handled by FormB: in "closed", namely to make prompt, trigger to FormA FormB and control way of "closed"
