Hi,

I use the .EventSinkService.NodeBoundsChanged event to check the place for the new position during dragging a shape.

So far it works fine. It also makes a hittest with other shapes and there I'm having trouble to find out the START-position of the dragged shape, if I want let the shape bounds back to the origin position.

For example:

I drag a shape -> the preview-shape shows me a new position:

a) if the place is free of other elements is that the new position for the shape. (works fine)

b) if the preview-shape hits an other element than jump back to the origin position. (how to find this position?)

You know this effect also from windows, if you drag a file in an unacceptable location the file stay on the origin postion.

I tried this in the eventfunction "Dim draggedshape As Nevron.Diagram.NShape = CType(args.Node, Nevron.Diagram.NShape)" but the location of the node is of course the current position and not the position where I started to drag the shape. 

I search something like DraggedShape.Startdragpostition or shape.position_befor_bouncing

Thanks in advance,

Leon
