Read this article it shows you that there currently is no official way of getting notified of the end of the rendering but instead shows you a trick that you could use.

I don't haev a proper solution for you, but you can make the following hack in the loaded event:

Dispatcher.BeginInvoke(new Action(delegate {      
        // here you are pretty shure that all rendering is done                
        // Put in your code here
        }), System.Windows.Threading.DispatcherPriority.ContextIdle, null); 

Probably it will also work with DispatcherPriority.Background, check it out.
