This simple enhancement of the Parent field and filter templates allows you to provide all
metadata information required to generate a
dynamic
list page that displays information
not only from the Product entity itself, but also from its parent entity, Supplier, without
having to create a custom page template. Figure 13.6 shows a screenshot of the Product
list page, which includes the
Country
property both as a filter control at the top of the
page and as a column in the
GridView
. Both display and filtering of
Country
property
values works in this dynamically generated page just as well as in the
custom
page created
with the help of the Parent field and filter templates earlier.
