I have a toolbar command where I like to change the position within the toolbar. The following code does not work:

NDiagramCommand cmd = nDiagramCommandBarsManager1.Commander.Commands.GetCommandFromId((int)DiagramCommand.ToggleSnapToGrid);
nDiagramCommandBarsManager1.Commander.Commands.Remove(cmd);
nDiagramCommandBarsManager1.Commander.Commands.Insert(0, cmd);
