There are lots of ways that you can display data in a list or grid. However, with a portrait orientation and a relatively small amount of screen real estate, tables (grids) are seldom a good way of displaying data. If you can provide more detail about the data you wish to display we may be able to advise more appropriately.

For an example of displaying data in a listbox using a viewmodel and databinding can be seen in the default code which is included when you create a new "Windows Phone Databound Application".
