In JScript, you can handle the events defined by a class, but you cannot define your own.
You cannot use this event in XAML.

A filter is any code that listens to PreProcessInput or PostProcessInput. Filters can modify the input staging area.

The handlers attached to PostProcessInput are invoked in reverse order so that handlers added by the users are invoked before handlers in the system.

Input is processed in WPF in the follow stages:

  1. Pre-process stage. The input manager raises the PreProcessInput event.

  2. Pre-notify stage. The input manager raises the PreNotifyInput event.

  3. The WPF input event or events are raised.

  4. Post-notify stage. The input manager raises the PostNotifyInput event.

  5. Post-process stage. The input manager raises the PostProcessInput event.
