DevExpress 的帮助文档是在太缺乏了，他自己的帮助只有简单描述，没有样例，而它的网站上的在线帮助只有利用它的设计器设计的ToolBar、PopupMenu ，没有利用代码开发的。

虽然要利用代码开发，可以参照它设计器背后的代码，但还是有些区别的。我最近就碰见了问题：

我通过反射初始化BarButtonItem，BarSubItem按钮实例，最后在主程序把这些按钮加到ToolBar上：

在用反射实例化BarSubItem时，要用该方法：

                        BarSubItem newItem = new BarSubItem();

                        newItem.Name = intMenuItemCount.ToString();

                        newItem.Id = intMenuItemCount++;

 newMenu.LinksPersistInfo.Add(new DevExpress.XtraBars.LinkPersistInfo((BarItem)item, beginGroup));

这里要注意：

1、Id必须唯一。

2、不要使用newMenu.AddItem((BarItem)item),这个方法会引起很多问题，如：beginGroup菜单分组无法实现， 我试图通过以下方法实现，但还是徒劳，而且有些编辑菜单不能使用该方法，如：BarToolbarsListItem工具栏列表菜单                   

                         BarItemLink itemLink = newMenu.AddItem((BarItem)item);

                          itemLink.BeginGroup = beginGroup;

3、在将实例化的BarSubItem加到ToolBar以后，还要递归把BarSubItem以及它的子菜单加入BarManager。

 private void AddMenuItem(DevExpress.XtraBars.BarItem menuItem)

        {

            if (menuItem != null)

            {

                //如果是编辑框工具条时使用

                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、如果右键菜单也是通过反射实现的，那么在加载右键菜单时需要注意：

 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;

}

//在此方法中注意 BarItemLink itemLink = (menuItem as BarSubItem).AddItem(item);此方法看似又多加了菜单，但实际不然，如果不用该方法，右键菜单中的菜单有子菜单时会无法显示。我就是让这个问题耗了我很多事间

 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);

                    }

                }

            }

        }
