Two controls are Container Controls: Group, and ControlGroup (Strictly speaking, Form is also a container.) A control that is contained by a container control (e.g. a Group control) will have the container control as its parent.
Contained by as used here needs to be defined. A control that is contained by a container control appears in the Object Tree as a child of the container control. Consider:
Here Checkbox1 is contained by Group1. But Radio1 is not.
Checkbox1 was created by visually placing it within the visual bounds of Group1. Radio1 was created outside the bounds and then dragged and dropped where it is now.
Because Checkbox1 was created within Group1, if you select Group1 and move it, Checkbox1 moves with the group – but Radio1 stays where it is.
How can I get Radio1 to move with Group1?
