DevExpress 組件動態在PopupMenu中添加項

示例中是：

private DevExpress.XtraBars.PopupMenu popupMenu1;
添加一些項：
 ((System.ComponentModel.ISupportInitialize)(this.popupMenu1)).BeginInit();
this.popupMenu1.LinksPersistInfo.AddRange(new DevExpress.XtraBars.LinkPersistInfo[] {
            new DevExpress.XtraBars.LinkPersistInfo(this.iCut),
            new DevExpress.XtraBars.LinkPersistInfo(this.iCopy),
            new DevExpress.XtraBars.LinkPersistInfo(this.iPaste),
            new DevExpress.XtraBars.LinkPersistInfo(this.iClear),
            new DevExpress.XtraBars.LinkPersistInfo(this.iFont, true),
            new DevExpress.XtraBars.LinkPersistInfo(this.iBullets)});
((System.ComponentModel.ISupportInitialize)(this.popupMenu1)).EndInit();
加入BeginInit 和 EndInit 才能正確顯示

后來看到后面的博文，變通下，用這個方法：

popupMenu1.AddItem(new 一個 item);

如果加載已有的項目，則用：

popupMenu1.AddItem(new DevExpress.XtraBars.LinkPersistInfo(this.iCut).Item);

原文：DevExpress 組件動態在PopupMenu中添加項

由於使用DevExpress 的控件，需要在PopupMenu動態添加項。根據PopupMenu的后台代碼，自己寫怎么添加都不顯示，不知道原因何在。代碼如下：

            BarButtonItem tBBI = new BarButtonItem();

            tBBI.Name = "Item1";

            tBBI.Caption = "myItem";

            this.barManager1.Items.Add(tBBI);

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

 

后來無意中,發現PopupMenu有一個AddItem方法，用了之后，可以了。很高興。但問題接踵而至。按鈕中的項，不能分組。繼續找原因。知道發現這篇博客：

很受啟發，尤其是關鍵代碼

        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;

        }
