Like subject says I'm trying to remove some commands I don't use from the DiagramCommandBarsManager.
I searched about it and found this:

I tried to remove the PDF Export... icon + command from the toolbar and from the "File" context menu but it didn't work, here is my code:

            NPdfExportCommand newD = (NPdfExportCommand)nDiagramCommandBarsManager1.Commander.Commands.GetCommandFromId((int)DiagramCommand.PdfExport);
            int index = nDiagramCommandBarsManager1.Commander.Commands.IndexOf(newD);
            nDiagramCommandBarsManager1.Commander.Commands.RemoveAt(index);
            nDiagramCommandBarsManager1.Refresh();

It disables the command so when I click the icon it doesn't show me anything... but I would like to remove the icon so it doesn't appear.
