Answer 1

As a test, this code hooked up to button moves the scrollbar with nothing else required:

scroller.ScrollToHorizontalOffset(scroller.HorizontalOffset + 10);

The content was very wide though. AnthonyWJones is correct in his comment. The content must be at least 250 + the width of your scrollviewer to have any effect. HorizontalOffset is the offset of the left side of the scrollview content.

Try smaller values when testing :)
