DevExpress 组件动态在PopupMenu中添加项

由于使用DevExpress 的控件，需要在PopupMenu动态添加项。根据PopupMenu的后台代码，自己写怎么添加都不显示，不知道原因何在。代码如下：

            BarButtonItem tBBI = new BarButtonItem();

            tBBI.Name = "Item1";

            tBBI.Caption = "myItem";

            this.barManager1.Items.Add(tBBI);

            this.pPop.LinksPersistInfo.Add(new LinkPersistInfo(tBBI));

 

后来无意中,发现PopupMenu有一个AddItem方法，用了之后，可以了。很高兴。但问题接踵而至。按钮中的项，不能分组。继续找原因。知道发现这篇博客：

很受启发，尤其是关键代码

        public PopupMenu CreateContextMenu()

        {

            PopupMenu contextMenu = new PopupMenu();

            contextMenu.Popup += new EventHandler(ContextMenuPopupHandler);

            foreach (object item in buildItems)

            {

                if (item is BarItem)

                {

                    bool beginGroup = false;

                    beginGroup = (bool)(item as BarItem).Tag;

                    //contextMenu.LinksPersistInfo.AddRange(new LinkPersistInfo[] { new LinkPersistInfo((item as             BarItem),         beginGroup) });

                    BarItem barItem = item as BarItem;

                    AddMenuItem(barManager, barItem);

                    //用LinksPersistInfo右键菜单不出来

                    //contextMenu.LinksPersistInfo.Add(new LinkPersistInfo(barItem, beginGroup));

                    BarItemLink itemLink = contextMenu.AddItem(barItem);

                    itemLink.BeginGroup = beginGroup;

                }

            }

            contextMenu.Manager = barManager;

            return contextMenu;

        }

学习了！
