This method raises the IComponentChangeService.ComponentChanged event.

Most designers that ship with the winsdklong, as well as the Visual Studio design-time environment, typically raise this event for you when a component in a project is changed, so most of the time you do not need to explicitly call this method. The appropriate System.ComponentModel.Design.IComponentChangeService events are automatically raised when a System.ComponentModel.PropertyDescriptor is used to change a property value or components are added or removed from the System.ComponentModel.Design.IDesignerHost container.

Before calling IComponentChangeService.OnComponentChanged(object, System.ComponentModel.MemberDescriptor, object, object), first call IComponentChangeService.OnComponentChanging(object, System.ComponentModel.MemberDescriptor) to indicate that a component is about to change, and make the change. Then call IComponentChangeService.OnComponentChanged(object, System.ComponentModel.MemberDescriptor, object, object) to raise the IComponentChangeService.ComponentChanged event.
