CommandBinding.Executed イベント

定義

この CommandBinding に関連付けられたコマンドが実行されたときに発生します。Occurs when the command associated with this CommandBinding executes.

public:
 event System::Windows::Input::ExecutedRoutedEventHandler ^ Executed;
public event System.Windows.Input.ExecutedRoutedEventHandler Executed;
member this.Executed : System.Windows.Input.ExecutedRoutedEventHandler 
Public Custom Event Executed As ExecutedRoutedEventHandler 
Public Event Executed As ExecutedRoutedEventHandler 

次の例では、ExecutedRoutedEventHandlerCanExecuteRoutedEventArgs ハンドラーを Open コマンドにマップする CommandBinding を作成します。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);
' Creating CommandBinding and attaching an Executed and CanExecute handler
Dim OpenCmdBinding As New CommandBinding(ApplicationCommands.Open, AddressOf OpenCmdExecuted, AddressOf OpenCmdCanExecute)

Me.CommandBindings.Add(OpenCmdBinding)

コマンドの実行時に MessageBox を作成する ExecutedRoutedEventHandler を次に示します。The following shows the ExecutedRoutedEventHandler which creates 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

注釈

RoutedCommand 実行すると、コマンドターゲットで PreviewExecuted イベントが発生します。When a RoutedCommand executes, it raises the PreviewExecuted event on the command target. PreviewExecuted イベントが処理されない場合は、コマンドターゲットで Executed イベントが発生します。If the PreviewExecuted event is not handled, the Executed event is raised on the command target. コマンドターゲットに特定のコマンドの CommandBinding がある場合、その CommandBindingExecuted ハンドラーが呼び出されます。If the command target has a CommandBinding for the specific command, the Executed handler for that CommandBinding is called. コマンドターゲットに特定のコマンドの CommandBinding がない場合、Executed イベントは、コマンドに関連付けられた CommandBinding を持つ要素を検索します。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. CommandBinding が見つからない場合、コマンドは処理されません。If a CommandBinding is not found, the command is not handled.
