	Hi Stoyan, I try to ZoomIn/ZoomOut the Diagram and save it to xml file. But when I get it back, the Diagram is restored to the original size and the ScrollViewer position is not correct. How can I save the ZoomFactor when Diagram is saved to xml file and bring it back without changing ScrollViewer position? The code I used to ZoomIn/Out is from the following link: http://mindfusion.eu/Forum/YaBB.pl?board=wpfdg_disc;action=display;num=123755029... Thanks a lot!

	Hi Chris, When saving, you could use the SaveToXml(XmlDocument) method and add elements for the zoom and scroll values to the XML document. When reading, call LoadFromXml(XmlDocument) and read the zoom and scroll values from your custom elements. If you have a version with source code, you might look for the internal DiagramView_SaveToXml / LoadFromXml methods and make them public - they save the Zoom, Scroll and Behavior properties in addition to the diagram data. I hope that helps, Stoyan
