The Control that is currently active on the ContainerControl.
The property activates or retrieves the active control on the container control.
In order to receive a valid value from this property, the object that calls it must either contain or be contained in the control it is calling. If one form tries to call another form's properties, it will receive an undefined value. In this case, you need to define your own communication mechanism between the forms to pass this data.
