The Parent object returns the form, object, or collection that contains the control. Returns the object or collection that contains another object or collection. Read-only.
object.Parent
The object placeholder represents an object expression that evaluates to an object.
Most objects have either a Parent property or a Collection property that points to the object's parent object in this object model. The Collection property is used if the parent object is a collection.
Use the Parent property to access the properties, methods, and controls of an object's parent object.

The Parent property is useful in an application in which you pass objects as arguments. For example, you could pass a control variable to a general procedure in a module, and use the Parent property to access its parent form.
