Hi, I'm pretty new to XAML, and my first task in a new job is to untangle a particularly malodorous collection of spaghetti code. Learning XAML at the same time as untangling this horror-show is proving somewhat beyond me, so my apologies for the homework-level questions I'm asking, these days. Anyway, I have the following XAML code: ...
