ButtonBaseThe ButtonBase marks the MouseLeftButtonDown event as handled in the OnMouseLeftButtonDown method and raises the Click event. Por lo tanto OnMouseLeftButtonDown , el evento nunca se producirá para un control que ButtonBaseherede de.Hence, the OnMouseLeftButtonDown event will never occur for a control that inherits from ButtonBase. En su lugar, se adjunta un controlador de PreviewMouseLeftButtonDown eventos al evento o AddHandler(RoutedEvent, Delegate, Boolean) se handledEventsToo llama a truecon establecido en.Instead, attach an event handler to the PreviewMouseLeftButtonDown event, or call AddHandler(RoutedEvent, Delegate, Boolean) with handledEventsToo set to true.
