InputManager.PreNotifyInput Event

Occurs when the PreProcessInput handlers have finished processing the input, if the input was not canceled.

Namespace:  System.Windows.Input
Assembly:  PresentationCore (in PresentationCore.dll)
'Declaration
Public Event PreNotifyInput As NotifyInputEventHandler
'Usage
Dim instance As InputManager 
Dim handler As NotifyInputEventHandler 

AddHandler instance.PreNotifyInput, handler
You cannot use this event in XAML.

A monitor is any code that listens to PreNotifyInput or PostNotifyInput. Monitors cannot modify the input staging area.

The handlers attached to PreNotifyInput 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.
