Question

Here is my code (Say we have a single button on the page that initiates the popup):

    private void button1_Click(object sender, RoutedEventArgs e)
    {            
        Rectangle rect = new Rectangle();
        rect.Width = 50;
        rect.Height = 50;

        Popup mypop = new Popup();
        mypop.Child = rect; // just to put something inside the popup for now           
        mypop.PopupAnimation = PopupAnimation.Slide;
        mypop.StaysOpen = false;
        mypop.PlacementTarget = button1; // open next to the button
        mypop.IsOpen = true;
    }

The popup just appears without animating, even though I set the PopupAnimation property.. anyone know why?

See this: Popup class:

A Popup control supports animation when the AllowsTransparency property is set to true and the application is running with full trust
