    I was trying to move a MarkedZone on my chart by changing its StartY and EndY in my code behind, but the MarkedZone disappears instead of moving to the new position unless I reload the silverlight app or refreshing the userControl. Is there anyway that I can make it update dynamically?

    We have tested your scenario by updating the marked zone on a button click and it works as expected on our side.Please, consider the following code snippet :
    private void button_Click(object sender, RoutedEventArgs e)
                MarkedZone markedzone = this.radChart.DefaultView.ChartArea.Annotations[0] as MarkedZone;
                markedzone.StartY = 0;
                markedzone.EndY = 1.5;
                markedzone.Background = new SolidColorBrush(Color.FromArgb(255, 248, 109, 90));

    Alternatively, you can clear all annotations on button click and set new ones if needed.

    Hope this helps.
