When exporting a chart, I first create a print friendly chart (a new instance of RadChart) where the legend, title, etc differs from the on-screen chart. The print friendly chart is then shown in a hidden window with a DocumentViewer. Should the chart be exported or saved before the print friendly chart is fully rendered, the saved bitmap is incorrect and incomplete. How can one determine that a RadChart has been completely rendered? Is there an event to which an event handler can be hooked?
