I am using a 3rd party control that exposes a bunch of dependency properties (ex: SomeNumber) but do not supply corresponding changed events (ex: SomeNumberChanged). I would like to handle the event when the value changes. I know there is the OnPropertyChanged callback when you register the DP, but is there a way to hook into this when you are not the one registering it?
Instead of trying to hook into the third party metadata, just make your own Dependency Property and data bind to the third party property.
This way, you’ll get the notification on your property, whenever either one is changed.
