Creating a horizontally scrolling list #wp7dev

I recently needed to show someone how to make a ListBox scroll horizontally rather than vertically. Here's what I did:

The key part is: '<StackPanel Orientation="Horizontal" />'
It's this that controls the direction. of item display.

The next two parts give us the correct scrolling behaviour that we want.
Setting 'ScrollViewer.HorizontalScrollBarVisibility="Auto"' enables horizontal scrolling.
Setting 'ScrollViewer.VerticalScrollBarVisibility="Disabled"' prevents vertical scrolling.

The thing to note is that setting XxxxScrollBarVisibility doesn't just control the visibility if the scrollbar it also controls whether scrolling in that direction is possible.
