	Hy stoyo. I'm trying to move a box when the lane where the box is contained is modified. But i'd like that FlowChart.UndoManager will ignore this operation. Code private void grid_CellBoundsChanged(object sender, CellBoundsEventArgs e) { .... box.Move(box.BoundingRect.X,(e.NewBounds.Top + box.Distance)); .... } In this event i want that UndoManager ignore box.Move. Is it possible? Tanks.

	As an alternative, is possible to have access to flow.UndoManager.History.Commands[index] parameters? Tanks.

	Hi, Try to filter out the ModifyItemCmd created for the box movement. Set some boolean flag before you start moving the boxes, and in the ActionRecording event handler set Cancel = true when that flag is set and the typeof(command) is ModifyItemCmd. I hope that helps, Stoyan

	Is also possible set the point where the undoManager will move the box after undoManager.Undo()?

	The node position won't be restored if you filter the command when ActionRecording is raised. You could create a composite command that contains all ModifyItemCmd instances created by the Move method, and also add to it your own command object that resizes the lane grid when undone or redone. Then calling Undo or Redo will move all nodes and resize the lane as a single operation. I hope that helps, Stoyan
