It’s a great post and an interesting control, however I work primarily using MVVM so having the Search handled by an event is a little bit cumbersome. To change the theme you will need to take the following few steps. Ran into a problem that needed solving that was kind of fun. Lenovo Yoga, Dell Inspiron Series 2-in-1, etc. One thing I like about WPF is the fact that you can take just about anything that you render on the canvas and dump it out as a bitmap file.
