	When I zoom the diagram, I need to get the user's viewable range instead of the visible range of the Diagram(the ruler's range by diagram coordinates). I need the coordinates of the ruler's top left point after zooming on the Diagram. I use the ZoomChanged event, but the coordinates obtained are incorrect, which is the coordinates before the zoom change. So, on the visual tree, I want to get the event after the Diagram is refreshed.

	The ruler repaints its scales from ScrollChanged event raised by its internal ScrollViewer, so you should be in sync if you get scroll position from same event - Code void MainWindow_Loaded(object sender, RoutedEventArgs e) { var sv = (ScrollViewer)Utilities.FindAncestor(diagram, typeof(ScrollViewer)); sv.ScrollChanged += new ScrollChangedEventHandler(sv_ScrollChanged); } void sv_ScrollChanged(object sender, ScrollChangedEventArgs e) { Debug.WriteLine(diagram.ScrollX + ":" + diagram.ScrollY); } Regards, Slavcho Mindfusion
