In WPF you can use the RenderTagetBitmap class to convert a Visual to an image, however this is not present in Sivlerlight. The following article details a rather long winded approach you can use to (sort of) save visuals in Silverlight. It's not a great solution though.

It also looks as though you can use this method in WriteableBitmap, although I have never tried it.
