This chapter began with an overview of the visual structure of the
LongListSelector. You then learned the basics of how to present flat and grouped lists using the control.
The chapter then dove into a sample app that allows the user to group a set of marketplace items. You saw how to create a
CustomGrouping class to allow the user to change the way the control groups items.
Finally, the chapter examined some more advanced features of the
LongListSelector with another sample that demonstrates how to display a list of contacts with the
LongListSelector using a grid layout.
