The corresponding tunneling event is PreviewExecuted.
When a RoutedCommand executes, it raises the PreviewExecuted event on the command target. If the PreviewExecuted event is not handled, the Executed event is raised on the command target. If the command target has a CommandBinding for the specific command, the Executed handler for that CommandBinding is called. If the command target does not have a CommandBinding for that specific command the Executed event bubbles up the element tree searching for an element that has a CommandBinding associated with the command. If a CommandBinding is not found, the command is not handled.
The following example creates a CommandBinding that maps an ExecutedRoutedEventHandler and a CanExecuteRoutedEventArgs handler to the Open command.
<Window.CommandBindings> <CommandBinding Command="ApplicationCommands.Open" Executed="OpenCmdExecuted" CanExecute="OpenCmdCanExecute"/> </Window.CommandBindings>
// Creating CommandBinding and attaching an Executed and CanExecute handler CommandBinding OpenCmdBinding = new CommandBinding( ApplicationCommands.Open, OpenCmdExecuted, OpenCmdCanExecute); this.CommandBindings.Add(OpenCmdBinding);
The following shows the ExecutedRoutedEventHandler which creates a MessageBox when the command is executed.
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
