I was wondering How do I add an image to a grid square and is it possible to line them up horizontally only as am only needing three grid squares and I want to use images for each square that when pressed will take the user to a different page in the app.
Any examples that show how to do this?
I strongly recommend going through the
Getting Started docs to get an overview of how to write Windows Store apps. This will address many of your questions and give you the tools to answer many others.
