NotifyInputEventHandler Delegate

Represents the method that will handle PreNotifyInput and PostNotifyInput events.

Namespace: System.Windows.Input
Assembly: PresentationCore (in presentationcore.dll)

public delegate void NotifyInputEventHandler (
	Object sender,
	NotifyInputEventArgs e
)
/** @delegate */
public delegate void NotifyInputEventHandler (
	Object sender, 
	NotifyInputEventArgs e
)
In XAML, you can use delegates but you cannot define your own.

Parameters

sender

The source of the event.

e

The event data.

The input staging area processes input into WPF events.

The NotifyInputEventHandler is used with the PreNotifyInput and PostNotifyInput events.

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.

When you create a NotifyInputEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events and Delegates.
