Dependency Property base value precedence

I often reference Adam Nathan‘s excellent Windows Presentation Foundation Unleashed. If you do any WPF development, you should definitely pick up a copy.

The following is from that book, and I’m posting it just to save me from having to find the table at the bottom of page 57 every time I need to know this:

Dependency property base values are determined using the following precedence:

1. Local value
2. Style triggers
3. Template triggers
4. Style setters
5. Theme style triggers
6. Theme style setters
7. Property value inheritance
8. Default value

That means when a style trigger doesn’t work, make sure you aren’t setting a local value. If you are, use a style setter instead.
