问题 I am using a ListBox control in a Windows Phone 7 application, and I would like to show a divider/line between the list rows.

It is very easy to wrap your ItemTemplate content in a Border control and specify the BorderThickness and BorderBrush. I went this way, because it doesn't require changes to
