DevExpress 组件动态在PopupMenu中添加项

示例中是：

private DevExpress.XtraBars.PopupMenu popupMenu1;
添加一些项：
((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 才能正确显示

后来看到后面的博文，变通下，用这个方法：

popupMenu1.AddItem(new 一个 item);

如果加载已有的项目，则用：

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

原文：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;

}
