Avalonia routed events are central to building interactive UIs. This skill covers defining custom RoutedEvent, handling bubbling or tunneling, and wiring handlers with AddHandler, RoutingStrategies, the OnApplyTemplate/PART pattern, or class-level static handlers via AddClassHandler.
Create a custom RoutedEvent on a control, attach handlers with AddHandler using the correct RoutingStrategies, and wire template parts in OnApplyTemplate.

To create a custom routed event in Avalonia, you define and register a RoutedEvent on your control, then attach handlers using AddHandler with the appropriate RoutingStrategies. This enables controls to respond to pointer, keyboard, or custom interactions across the visual tree.
Avalonia routing strategies control event propagation across the visual tree. Bubble routes events upward from child to parent, Tunnel routes downward from parent to child, and Direct routes only to the originating control without traversing the visual tree.
You override OnApplyTemplate in your Avalonia control to locate named template parts using the PART_ pattern. This allows you to safely wire event handlers to visual elements defined in the control template after it has been applied.
Yes, you can attach static class-level handlers using AddClassHandler in Avalonia. This allows you to define routed event handling logic statically at the class level, ensuring consistent event behavior across all instances of a control without manually wiring each instance.
Use AddHandler in Avalonia when you need to intercept routed events with specific RoutingStrategies, such as handling tunneling events before child controls process them, or when attaching handlers to events that bubble up through nested controls in the visual tree.
