Hi,

We use the OnChildModified method to initialize a resize when removing a child node e.g. dragging a child E-shape node out of a parent E-shape (upper half). As I understand it, OnChildModified is only called when the AttachTo method is called on the 2 nodes. I followed this with the debugger and I do see that the parent has a SubordinateGroup with the child node in the AttachedNodes collection and the child has a MasterGroup with the parent as MainItem. However, the OnChildModified isn't called if I drag the child away from the parent (I put a breakpoint in the method). Do you have an idea as to why this doesn't happen?

protected override void OnChildModified(DiagramNode node, AdjustmentHandles handle)
        {
            base.OnChildModified(node, handle);
            if ((node.GetCenter() - this.GetCenter()).Length > 50)
                SendResizeNodeOnChildRemoveRequest((BRNode) node);
        }
 

The 2 nodes do seem to be attached. After aligning the 2 nodes, if I drag the parent the child also moves accordingly.

Thanks!

Vincent
