Description
Indicates whether a specified control exists within the control.
Use ContainsControl to find out if a particular control exists within this control. ContainsControl returns true if the specified value of the Control parameter is a child control of this control. The Control parameter need not be an immediate child (in the Controls property), but may be contained in a child of the control, or in a child of a child of the control, for indefinitely many levels deep.
If the method returns false, the specified control is not within the control.
