Comentarios

El control Parent valor de propiedad no puede ser el mismo que el Form devuelto por FindForm método.The control's Parent property value might not be the same as the Form returned by FindForm method. Por ejemplo, si un RadioButton control está dentro de un GroupBox control y el GroupBox se encuentra en un Form, el RadioButton del control Parent es el GroupBox y el GroupBox control Parentes el Form.For example, if a RadioButton control is contained within a GroupBox control, and the GroupBox is on a Form, the RadioButton control's Parent is the GroupBox and the GroupBox control's Parent is the Form.
