给TreeList的根和子节点弹出不同的右键菜单

好象没几个人用dev的treelist,好早就想实现这个效果，经过一个多小时的摸索，终于找到了实现方法

定义两个不同的popup contentMenu
在mouse_down事件中处理

private   void  JobTree_MouseDown( object  sender, MouseEventArgs e)
         {
            if (e.Button == MouseButtons.Right)
            {
                DevExpress.XtraTreeList.TreeListHitInfo hInfo = this.JobTree.CalcHitInfo(new Point(e.X, e.Y));
                if (hInfo.HitInfoType == DevExpress.XtraTreeList.HitInfoType.Cell) //在单元格上右击了
                {
                    if(hInfo.Node.RootNode.Id==hInfo.Node.Id) //说明是根节点　站点
                        this.barManager1.SetPopupContextMenu(this.JobTree, this.popupSite);
                    else  //任务
                        this.barManager1.SetPopupContextMenu(this.JobTree, this.popupJob);
                }
                
            }
        }
