DevExpress 組件ToolBar、PopupMenu 使用有感

DevExpress 的協助文檔是在太缺乏了，他自己的協助只有簡單描述，沒有範例，而它的網站上的線上協助只有利用它的設計器設計的ToolBar、PopupMenu ，沒有利用代碼開發的。
雖然要利用代碼開發，可以參照它設計器背後的代碼，但還是有些區別的。我最近就碰見了問題：
我通過反射初始化BarButtonItem，BarSubItem按鈕執行個體，最後在主程式把這些按鈕加到ToolBar上：
在用反射執行個體化BarSubItem時，要用該方法：
                        BarSubItem newItem = new BarSubItem();
                        newItem.Name = intMenuItemCount.ToString();
                        newItem.Id = intMenuItemCount++;
 newMenu.LinksPersistInfo.Add(new DevExpress.XtraBars.LinkPersistInfo((BarItem)item, beginGroup));
這裡要注意：
1、Id必須唯一。
2、不要使用newMenu.AddItem((BarItem)item),這個方法會引起很多問題，如：beginGroup菜單分組無法實現， 我試圖通過以下方法實現，但還是徒勞，而且有些編輯菜單不能使用該方法，如：BarToolbarsListItem工具列列表菜單                   
                         BarItemLink itemLink = newMenu.AddItem((BarItem)item);
                          itemLink.BeginGroup = beginGroup;
3、在將執行個體化的BarSubItem加到ToolBar以後，還要遞迴把BarSubItem以及它的子功能表加入BarManager。
 private void AddMenuItem(DevExpress.XtraBars.BarItem menuItem)
        {
            if (menuItem != null)
            {
                //如果是編輯框工具條時使用
                if (menuItem is BarEditItem)
                {
                    this.BarMenuManager.RepositoryItems.Add((menuItem as BarEditItem).Edit);
                }
                this.BarMenuManager.Items.Add(menuItem);
                if (menuItem is DevExpress.XtraBars.BarSubItem)
                {
                    DevExpress.XtraBars.LinksInfo linksInfo = (menuItem as DevExpress.XtraBars.BarSubItem).LinksPersistInfo;
                    for (int i = 0; i < linksInfo.Count; i++)
                    {
                        AddMenuItem((BarItem)linksInfo[i].Item);
                    }
                }
            }
4、如果右鍵菜單也是通過反射實現的，那麼在載入右鍵菜單時需要注意：
 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右鍵菜單不出來
                        //contextMenu.LinksPersistInfo.Add(new LinkPersistInfo(barItem, beginGroup));
                        BarItemLink itemLink = contextMenu.AddItem(barItem);
                        itemLink.BeginGroup = beginGroup;
                    }
                }
                contextMenu.Manager = barManager; 
            return contextMenu;
}
//在此方法中注意 BarItemLink itemLink = (menuItem as BarSubItem).AddItem(item);此方法看似又多加了菜單，但實際不然，如果不用該方法，右鍵菜單中的菜單有子功能表時會無法顯示。我就是讓這個問題耗了我很多事間

 private void AddMenuItem(DevExpress.XtraBars.BarManager barManager,DevExpress.XtraBars.BarItem menuItem)
        {
            if (menuItem != null)
            {             
                barManager.Items.Add(menuItem);
                if (menuItem is DevExpress.XtraBars.BarSubItem)
                {
                    DevExpress.XtraBars.LinksInfo linksInfo = (menuItem as DevExpress.XtraBars.BarSubItem).LinksPersistInfo;
                    int count = linksInfo.Count;
                    for (int i = 0; i < count; i++)
                    {
                        BarItem item = (BarItem)linksInfo[i].Item;
                        item.Manager = barManager;

                        BarItemLink itemLink = (menuItem as BarSubItem).AddItem(item);
                        itemLink.BeginGroup = linksInfo[i].BeginGroup;
                        AddMenuItem(barManager, item);
                    }
                }
            }
        }
