Question

    // Property
    IsSelectedProperty = DependencyProperty.Register("IsSelected", typeof(bool), typeof(MyControl),new UIPropertyMetadata(false, 
        new PropertyChangedCallback(OnIsSelectedChanged)));

    // Event
    public event RoutedEventHandler SelectedChanged
    {
        add { AddHandler(SelectedChangedEvent, value); }
        remove { RemoveHandler(SelectedChangedEvent, value); }
    }

    // How Do I Raise the Event ???
    static void OnIsSelectedChanged(DependencyObject source, DependencyPropertyChangedEventArgs e)
    {
        var s = (MyControl)source;

        // ???? 
        s.OnSelectedChanged(source, EventArgs.Empty);

Answer 1

if you are trying to raise a RoutedEvent, just call this.Raise(...);

if you are calling in a static method, call it like so:

((MyControl)s).Raise( new RoutedEventArg( MyControl.MyEvent ) );
