Examples

The following example creates an ExecutedRoutedEventHandler that opens a MessageBox when the command is executed.

void OpenCmdExecuted(object target, ExecutedRoutedEventArgs e)
{
    String command, targetobj;
    command = ((RoutedCommand)e.Command).Name;
    targetobj = ((FrameworkElement)target).Name;
    MessageBox.Show("The " + command +  " command has been invoked on target object " + targetobj);
}

Private Sub OpenCmdExecuted(ByVal sender As Object, ByVal e As ExecutedRoutedEventArgs)
    Dim command, targetobj As String
    command = CType(e.Command, RoutedCommand).Name
    targetobj = CType(sender, FrameworkElement).Name
    MessageBox.Show("The " + command + " command has been invoked on target object " + targetobj)
End Sub

Remarks

ExecutedRoutedEventHandler represents the method that implements the command logic of a RoutedCommand. Separating the implementation logic from the command allows the command to be invoked from different sources and types and enables the centralization of command logic.

This event data class is also used for CommandManager.Executed and CommandManager.PreviewExecuted. But most practical handlers will handle the Executed events from a particular CommandBinding, rather than work at the CommandManager level.

Properties

Command	Gets the command that was invoked.
Handled	Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. (Inherited from RoutedEventArgs)
OriginalSource	Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. (Inherited from RoutedEventArgs)
Parameter	Gets data parameter of the command.
RoutedEvent	Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. (Inherited from RoutedEventArgs)
Source	Gets or sets a reference to the object that raised the event. (Inherited from RoutedEventArgs)

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
InvokeEventHandler(Delegate, Object)	When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. (Inherited from RoutedEventArgs)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
OnSetSource(Object)	When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. (Inherited from RoutedEventArgs)
ToString()	Returns a string that represents the current object. (Inherited from Object)
