KeyboardEventHandler Delegate
Represents the method that will handle keyboard-related routed events.
Assembly: PresentationCore (in PresentationCore.dll)
'Declaration Public Delegate Sub KeyboardEventHandler ( _ sender As Object, _ e As KeyboardEventArgs _ ) 'Usage Dim instance As New KeyboardEventHandler(AddressOf HandlerMethod)
In XAML, you can use delegates but you cannot define your own.
Parameters
- sender
- Type: System.Object
The object where the event handler is attached.
- e
- Type: System.Windows.Input.KeyboardEventArgs
The event data.
No existing keyboard event in WPF uses the KeyboardEventHandler delegate. KeyboardEventHandler uses the KeyboardEventArgs base class as its event data class. KeyboardEventArgs serves as the base class for the more specific KeyEventArgs and KeyboardFocusChangedEventArgs event data classes. These event data classes are used by the KeyEventHandler and KeyboardFocusChangedEventHandler delegates, and those delegates are used by existing WPF events such as UIElement.KeyDown and UIElement.LostKeyboardFocus.
