Exemples

L’exemple suivant implémente un gestionnaire qui modifie le curseur sur une région DisplayArea nommée (non affichée). Le commentaire indique une UIElement utilisation, mais en fait cet exemple serait identique si DisplayArea était un FrameworkContentElement.

private void CursorTypeChanged(object sender, SelectionChangedEventArgs e)
{
    ComboBox source = e.Source as ComboBox;

    if (source != null)
    {
        ComboBoxItem selectedCursor = source.SelectedItem as ComboBoxItem;

        // Changing the cursor of the Border control 
        // by setting the Cursor property
        switch (selectedCursor.Content.ToString())
        {
            case "AppStarting":
                DisplayArea.Cursor = Cursors.AppStarting;

Remarques

Pour supprimer les menus contextuels fermants, les gestionnaires de l’événement doivent le marquer comme géré.

Pour utiliser cet événement en tant que dans un style, vous devez référencer l’identificateur d’événement EventTrigger de service sous-jacent :

<EventTrigger RoutedEvent="ContextMenuService.ContextMenuClosing">
  <!-- storyboard here ... -->
</EventTrigger>

(Cette utilisation est nécessaire, car l’implémentation d’événement sur FrameworkContentElement qui expose l’événement de service sous-jacent ne mappe pas correctement l’identificateur ContextMenuClosing pour une utilisation dans les déclencheurs).
