Difference between Framework.Triggers and Style.Triggers?

Question

There are two properties of same type but exists in different classes.

• FrameworkElement.Triggers Property
• Style.Triggers Property

This confuses me a lot, and so I've few questions whose answer I'm looking for:

• Why two properties of same type exist?
• When should I use what?
• What one can do that other cannot?

Answer 1

As the documentation page that you've linked to in the question says:

FrameworkElement.Triggers can only contain EventTriggers and is not usually used. You cannot define (Property based) Triggers or (data-bound value based) DataTriggers with this method.

For most practical purposes, you should be using Style.Triggers or DataTemplate.Triggers or ControlTemplate.Triggers. (Sorry for adding to the confusion).
