Saves the required information on the current state of the View Item to the Application Model.
This method is called by the View.SaveModel method for each View Item, to save their current state before setting a new value for the View.Model property. After this property is changed, the View's settings are updated and the controls (View Items and their controls) are created (recreated, if they were previously created). So, you do not have to call this method manually.
This method calls the SaveModelCore method, which does nothing. However, you can override this method in the ViewItem class' descendants, so that the required settings of your View Item's control are saved to the Application Model.
