Figure 22.28 demonstrates a so-called master/detail view—one part of the GUI (the master) allows you to select an entry, and another part (the details) displays detailed information about that entry. When the app first loads, it displays the name of the first author in the data source and that author’s books (Fig. 22.28(a)). When you use the buttons on the
Binding-Navigator to change authors, the app displays the details of the books written by the corresponding author (Fig. 22.28(b)). This app only reads data from the entity data model, so we disabled the buttons in the
BindingNavigator that enable the user to add and delete records.
