	hi,I Create several User-defined ShapeNode in my Code and I want to use the toolbar that when I click one button in toolbar(it's mean the related shapenode shoud be created after I click in the diagram) For example： I click the "Add New EvElectronicSwitch" button in toolbar,and move the mouse into the diagram and click.then the "EvElectronicSwitch" Shapenode should be create at the mouse�s position. Do you know how to do this？and I attach my project to you for asking for you help. thanks

	Hi, If using standard ShapeNodes, you could set Diagram.DefaultShape from toolbar click handlers, and call Factory.CreateShapeNode from Diagram.Clicked handler: Code Size newNodeSize = new Size(100, 100); private void OnDiagramClicked(object sender, DiagramEventArgs e) { diagram.Factory.CreateShapeNode( e.MousePosition - new Vector(newNodeSize.Width, newNodeSize.Height) / 2, newNodeSize); } // in toolbar click diagram.DefaultShape = Shape.FromId("EvElectronicSwitch"); If using custom node types, you could keep a prototype node for each type, set a current prototype from toolbar handlers, and handle Diagram.Clicked by call Diagram.Nodes.Add(currentPrototype.Clone()); I hope that helps, Stoyan
