CommandBinding.Executed Event
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
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 Event Type
Examples
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)
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
Remarks
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.
