CSharpUtilities::RoutedKeyEventArgs Class Reference

---

Detailed Description

Encapsulates arguments for KeyDown, KeyUp and KeyPress .NET events for events that may �bubble up� the source component's parent chain.

This is simply a convenience class whose main role is to allow for the exposure of multiple key events via a single event. This helps in situations where we're interested in bubbling up all significant key events without having to expose three new events on each parent component through which the bubbling occurs.
