	Hi, If i have a DiagramNode in a diagram, i am able to access the diagram by DiagramNode.Parent property. Same way, can i access DiagramView from a diagram node? Thanks Chiru

	Hi, Neither a Diagram nor its nodes know what DiagramViews they are displayed in. There's a way to access the view from a DiagramNode.Draw override - use the TargetView property of the options argument. If you are using multiple views and need to access them in other situations, you could build a Dictionary<Diagram, List<DiagramView>> map that lets you find them. I hope that helps, Stoyan

	Code private Dictionary<Diagram, List<DiagramView>> viewMap = new Dictionary<Diagram, List<DiagramView>>(); void AddView(Diagram d, DiagramView v) { if (!viewMap.ContainsKey(d)) viewMap[d] = new List<DiagramView>(); viewMap[d].Add(v); } List<DiagramView> GetViews(DiagramNode node) { return viewMap[node.Parent]; } Call AddView each time you create a new view for a diagram, and GetViews when you need to find out the views that display some node. I hope that helps, Stoyan
