                //add items to barmanager
                barManager1.Items.Add(btnitem);
                //create links between bar items and popup
                buttonContextMenu.ItemLinks.Add(barManager1.Items["barButtonItem1" + i]);
            }

            //finally set the context menu to the control or use the showpopup method on right click of control
            barManager1.SetPopupContextMenu(btnshowPop, buttonContextMenu);
