Introduction
Let’s imagine a scenario in which you have a series of Excel files (.xlsx) on your computer but you don’t have any Microsoft Office installed. What can we do if we want to examine the content of these files?
In this article we will describe a small Silverlight application allowing you to open and view these files and also create line series graphs. I used this exercise as laboratory to familiarize myself with some of the new features of Silverlight 4 like, for instance, drag&drop of files from local folders to the application, drag&drop between controls in the application, right click event handling, theming and so on.
