There are three types of Routed events in WPF. They are :
Direct : This event can only be raised by the element in which it was originated.
Tunneling : This event is first raised by the element in which it was originated and then it gets raised by each consecutive container in the visual tree.
Bubbling : This event is first raised by the uppermost container in the visual tree and then gets raised by each consecutive container lying below the uppermost one, till it reaches the element it where it was originated.
