Horizontal ScrollViewer

If you want to control a scrollviewer from left-to-right instead top-to-bottom,you can use this trick.

Set ScrollViewer HorizontalScrollBarVisibility property as:

HorizontalScrollBarVisibility="Visible"

By default,its set to "Disabled".

This will help you to navigate from left-to-right and opposite right-to-left

If you have a Grid bigger than ScrollViewer,then you'll be applying a Panorama-like effect

Hope this trick helps!
