Behaviour prop. of Diagram and selection retangle (Read 1101 times)

	Hi, if I set the behaviour property of the diagram to 'Modify', I get the selection retangle, when I click and hold the left mouse button. Is it possible to deactivate this selection retangle? We just want to select single nodes. This also happens with the behaviour 'Custom', when the NodeCreating event is canceled. One possible way could be to set the behaviour to 'DoNothing', but in that case we also have to handle the selection directly in the mouseevents and need to find the node to select via the position of the mousecursor. But perhaps you have a better idea. Thanks for your help. Kai-Uwe

	Hi, You can do that via custom behavior class that overrides StartDraw as below. Code public override InteractionState StartDraw(Point point) { DiagramItem ac = Diagram.ActiveItem; int handle = 0; if (ac != null && !ac.NotInteractive() && ac.HitTestHandle(point, ref handle)) return new InteractionState(ac, handle, Action.Modify); return null; } I hope that helps, Stoyan
