A friend contacted me yesterday asking me how to enable some sort of side-to-side scrolling of images, similar to the way to that the Pictures Viewer works. He looked at taking a ListBox, turning it on its side and just scrolling sideways, but it didn’t give him the “feel” that he wanted. I thought it would be a fun diversion from the other stuff I was doing to use this request as an excuse to start looking at the gesture support in WP7.
As it turns out, doing this was very easy, and only required the addition of 2 libraries – both from the XNA Framework for WP7. I’ll use this blog post to document how I did it, and hopefully come back later and add some snazzy transitions and other stuff in the future.
