Description
Destroys all of the windows controls that implement the combo box.
The DestroyWnd method calls DestroyWindowHandle to release the underlying Windows control. TCustomCombo overrides the inherited method to reset the EditHandle and ListHandle properties once the underlying Windows controls are gone.
