I’m dragging a node into the diagram. Upon drop, I want to display a Dialog to enter additional Information for the node (which until then is only a kind of proxy node to have the visual effect of dragging a node). I am currently fiddling around with the dragging tool DoDrop method. But somehow, the node which I manipulate there seems to get removed later on and re-added to the model (but without my modifications).
Any idea or hint how I could implement this requirement?
Any help is appreciated,
