UIElement.RaiseEvent Method

Raises a specific routed event. The RoutedEvent to be raised is identified within the RoutedEventArgs instance that is provided (as the RoutedEvent property of that event data).

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

'Declaration
Public Sub RaiseEvent ( _
	e As RoutedEventArgs _
)

Parameters

e
Type: System.Windows.RoutedEventArgs

A RoutedEventArgs that contains the event data and also identifies the event to raise.

Implements

IInputElement.RaiseEvent(RoutedEventArgs)

The e parameter is typed as the common base type for all routed event data; however, the event data should be given as the most specific event data type that is available for the event being raised, because RoutedEventArgs derived classes contain the actual specific data properties that are intended for the specific event when it is raised.

RoutedEventArgs is not just the state properties for the event; it also identifies which routed event to raise. This event-raising pattern and the routed event data both differ from common language runtime (CLR) events and data classes, which typically just contain properties that are related to the event.

The following example creates event data, appends the event identifier to the data, and then uses the event data instance to raise a custom routed event.

Private Sub RaiseTapEvent()
    Dim newEventArgs As New RoutedEventArgs(MyButtonSimple.TapEvent)
    MyBase.RaiseEvent(newEventArgs)
End Sub
