You must snoop into your app..

Via John Gossman...  

At first, I could not believe this there would be a utlility that helped me troubleshoot my WPF bindings... but snoop does :)  ...

This also walks you through Visual Tree ( a trick/utlity I use often now a days)

It just happened that I was messing w/ a dynamic layout for overflow stuff ... and snoop also looks handy because I can check exactly the size of my controls as I resize...
