Dependency Properties

If开发者_开发百科 I am setting one dependency property equal to another dependency property, will they automatically get updated if one chagnes, or do I still need to bind them. Also if two dp are part of the same object (same type too) and I set them equal to each does the same apply as above, or only this case works and the one above doesn't?

will they automatically get updated if one chagnes, or do I still need to bind them

No. Each is a separate property, and setting one to the other just sets the value. If you want them to be "bound together" then you should create a binding that binds them together.

This is true whether they're in the same class or different classes.
