下面是今天实际例子，动态加载菜单的代码。非常好用哦

 下面有两种方式添加事件：

MenuItem mi = new Ext.Net.MenuItem(entity.FullName)

                {

                    IconCls = iconCls,

                    Menu =

                        {

                            new Ext.Net.Menu

                            {

                                Items = {

                                  new Ext.Net.MenuItem { IconCls="x-loading-indicator", Text="Loading...", CanActivate=false, HideOnClick=false }

                                },

                                TagString = entity.FullName,

                                Loader = new ComponentLoader

                                {

                                    Mode = LoadMode.Component,

                                    DirectMethod = "#{DirectMethods}.Items",//加载方法

                                    RemoveAll = true,

                                    Params = {//设置调用事件时给的参数

                                        new Ext.Net.Parameter("tag", "this.tag", ParameterMode.Raw),

                                        new Ext.Net.Parameter("id", entity.Id.ToString(), ParameterMode.Raw)

                                    }

                                }

                            }

                        }

                     //第一种方法，在初始时给listeners事件初始

                    // ,Listeners =

                    //{

                    //    Click = { Handler = "loadMenuExample('" + this.UserInfo.GetUserParameter(entity.NavigateUrl) + "','" + entity.Id + "','" + entity.FullName + "','" + iconCls + "');" }

                    //}

                };

                var childList = this.UserModuleList.Where(child => child.ParentId != null && child.ParentId.ToString().Equals(entity.Id.ToString())).OrderBy(child => child.SortCode);

                if (childList.Count() <= 0) //是否有子菜单，如果有不本级菜单不加载事件. 第二种方式：在创建完menuitem时再追加进去事件

                    mi.Listeners.Click.Handler = "loadMenuExample('" + this.UserInfo.GetUserParameter(entity.NavigateUrl) + "','" + entity.Id + "','" + entity.FullName + "','" + iconCls + "');" ;

                items.Add(mi);

 

 

调用的Items方法使用：

 

[DirectMethod]

        public new string Items(Dictionary<string, string> parameters)

        {

            //System.Threading.Thread.Sleep(1500); //emulate net delay

            string tag = parameters["tag"];

            string id = parameters["id"];

 

        ｝
