	Hi Stoyan, We have nodes with attached subordinate nodes. If we select the parent node and we move it (using the mouse) all the subordinate nodes follow the parent node automatically. If in the NodeModifyig event we set e.cancel=true and we release the mouse the selected (parent) node comes back to its original position but the subordinate nodes position is not restored. Is it possible to automatically reset subordinate nodes position too? Best Regards, Danilo

	Hi Danilo, Setting e.Cancel in my test app returns the attached nodes to their original locations. Is there anything else that you do from the NodeModifying handler? Stoyan

	Hi Stoyan, In effect setting only e.Cancel=true it works well. In my NodeModifying event I call the Move method on the parent node because I want to keep aligned to the grid one of its point (not the standard top left point) This Move seems causing the problem. In attach you find a simplified example reproducing the issue. Danilo

	Hi Danilo, Calling Move to change nodes positions from validation events isn't that good idea because it clears some internal flags used during interaction. Using the more lower-level SetBounds method seems to work though: Code private void TubeDesignerDiag_NodeModifying(object sender, NodeValidationEventArgs e) { var dstPt = new Point(e.Node.Bounds.X + 1, e.Node.Bounds.Y - 1); var r = new Rect(dstPt, e.Node.Bounds.Size); e.Node.SetBounds(r, false, true); e.Cancel = true; } I hope that helps, Stoyan

	OK Stoyan, your solution is working perfectly. Thank you, Danilo
