RoutedEventArgs Class (System.Windows)

.NET Framework Class Library for Silverlight

RoutedEventArgs Class

Contains state information and event data associated with a routed event.

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

Syntax

Visual Basic (Declaration)

Public Class RoutedEventArgs _
    Inherits EventArgs

Visual Basic (Usage)

Dim instance As RoutedEventArgs

public class RoutedEventArgs : EventArgs

Remarks

This class is responsible for packaging the event data for a routed event, providing extra event state information, and is used by the event system for invoking the handler associated with the routed event.

The most relevant information carried in the event data is the OriginalSource, which reports the object that first raised the event. In the case of a bubbling routed event, this could be a different object in the element tree than the object where the handler being invoked is attached.

In WPF, there is a concept of a Source property that is separate from OriginalSource. This distinction is not present in Silverlight 2, because classes cannot adjust the reported source of a routed event in the Silverlight 2 event system. (In WPF, control classes sometimes adjust the event source as part of their compositing logic.)
