Examples

The following example implements a handler that changes the cursor over a named region DisplayArea (not shown). The comment hints at a UIElement usage, but in fact this sample would be identical if DisplayArea were a 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;
                break;
            case "ArrowCD":                        
                DisplayArea.Cursor = Cursors.ArrowCD;
                break;
            case "Arrow":
                DisplayArea.Cursor = Cursors.Arrow;
                break;
            case "Cross":
                DisplayArea.Cursor = Cursors.Cross;
                break;

Remarks

To suppress closing context menus, handlers of the event should mark it as handled.

To use this event as an EventTrigger in a style, you must reference the underlying service event identifier:

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

(This usage is required because the event implementation on FrameworkContentElement that exposes the underlying service event does not correctly map the ContextMenuClosing identifier for use in triggers).
