Control.Parent
Remarks
Use the Parent keyword to access the properties, methods, or controls of a control's container object. You can also use the Parent object reference to access the container object of a page or form.
The Parent keyword is useful in an application in which you pass controls as arguments. For example, you can pass a control variable to a general procedure and use the Parent object reference to access its container object.
You can also use the Parent object reference for objects in a control class that have been placed on an unknown form.
