CommandBinding.Executed 事件
重要
部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
與此 CommandBinding 相關聯的命令執行時發生。
public:
event System::Windows::Input::ExecutedRoutedEventHandler ^ Executed;C#
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 下列範例會建立 ，CommandBinding將 和 CanExecuteRoutedEventArgs 處理程式對應ExecutedRoutedEventHandler至 Open 命令。
XAML
<Window.CommandBindings>
<CommandBinding Command="ApplicationCommands.Open"
Executed="OpenCmdExecuted"
CanExecute="OpenCmdCanExecute"/>
</Window.CommandBindings>
C#
// 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)
以下顯示 ExecutedRoutedEventHandler 執行命令時所建立 MessageBox 的 。
C#
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
RoutedCommand執行時，它會在命令目標上引發 PreviewExecuted 事件。 PreviewExecuted如果未處理事件，則會Executed在命令目標上引發事件。 如果命令目標具有 CommandBinding 特定命令的 ，則會 Executed 呼叫該命令 CommandBinding 的處理程式。 如果命令目標沒有 CommandBinding 該特定命令的 ，事件 Executed 就會向上反升元素樹狀結構，以搜尋與 CommandBinding 命令相關聯的專案。 CommandBinding如果找不到 ，則不會處理命令。
