As the diagram suggest, from the View hierarchy on the left we can remove the CommentsView and all the child view, such as CommentsList, CommentsInsert, CommentsEdit and CommentsPreview will be removed as well. The hierarchy beneath CommentsView will be completely change also if we replace the CommentsView View some other View.
Finally, we can add CommentsView View to another hierarchy (perhaps in a different module) and at the same time all the child views of the CommentsView will be moved to this new hierarchy. You can find out more about this approach in this article and also examine the sample products module to see the implementation where CommentsView View has been transplanted from Generic Content module to Products module.
The image above depicts an imaginary hierarchy of Views, where the top level View is Control Panel, followed by ShopsView and finally the last View in the current hierarchy is NewShopView. Since all the ViewModeControls have Host property, we can call the Host property to access the immediate parent, but since immediate parent is also a View mode control, we can also call it’s Host property to access its parent and so on.
So on the image, we see how we can access the ShopChainName property of the ShopsView, by simply calling this.Host.ShopCainName on NewShopView. If we need to go all the way to the top of the hierarchy, we can call this.Host.Host to get access to the members of the top View two nodes up the hierarchy.
