	Hi Mindfusion support team, in the WPFDiagram library the Dirty flag gets set to true as soon as a DiagramItem gets selected. In our project we are using the Dirty flag to indicate if we have pending changes (enabling save button and notifying the user of unsaved changes). This is really annoying for the user as he has not really changed anything in the diagram. Would it be possible to remove this behavior and set the Dirty flag only if there was really a change. thanks, Christoph

	When I set breakpoint into DirtyChanged event hadler I see the same bahavior as topic starter. But it goes into this handler 2 times: first with Dirty == true and second with Dirty == false. That's why in our project this behavior doesn't disturb the user

	Hi Christoph, The control saves the selection state of items too when you call SaveToXml, so the Dirty flag is set when selection changes. You could set your own bool flag from handlers of the following events if you wish to ignore selection changes: NodeCreated,NodeModified,NodeDeleted,NodeTextEdited LinkCreated,LinkModified,LinkDeleted,LinkTextEdited I hope that helps, Stoyan
