	Two questions: 1) When a shape is dropped onto a diagram, is it possible to automatically make sure that the shape is aligned to the grid? I think I can do that algorithmically myself, but I was wondering if there is a property setting that handles this itself? 2) I'd like to make sure that the default diagram behavior (when the mouse drags a rectangle on the diagram) is that nothing at all happens. Right now, a shape object is drawn, but I'd like nothing to happen.

	1) You could call the Diagram.AlignPointToGrid method to find out which grid point is nearest to the mouse position, and call DiagramNode.Move to move the node there. 2) Set DiagramView.Behavior = DoNothing. I hope that helps, Stoyan

I hope that helps, Stoyan Well, the current Behavior is LinkShapes, which is good, since I can then link shapes that are already in the view. However, if I depress the left mouse button while the cursor is not over a shape, then the behavior is to draw a shape. I only want to prevent that latter behavior, not the linking. Jon
