Interactivity.Behavior vs attached properties

Question

I\'m trying to find some differences between these approaches. Is there any situation where behaviors are used and the same functionality could not be done with attached propert

Answer 1

I tend to use Behaviors to add functionality which makes visible changes. Whereas I use attached properties to add additional information to an object which is subsequently used by other objects.

E.g. Grid.Row makes a good attached property, as it's used by the Grid and not the target. On the other hand, AutoCorrect would make a good behaviour, as this will make visible changes on the object.
