The Difference Between Routed Events and Direct Events in WPF

In WPF, the main difference between routed events and direct events is the routing strategy they follow.

Direct Events:

Direct events in WPF follow a simple bubbling or tunneling route. This means that the event is raised and handled within the same element where it occurred.

Routed Events:

Routed events in WPF follow a complex route through the visual tree, allowing events to be handled by multiple elements. Routed events can be handled at different levels in the visual tree, such as the originating element, its ancestors, or the entire application.

Understanding the difference between routed events and direct events is crucial for effective event handling and UI development in WPF.
