Ext.Net动态加载菜单执行事件

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"];
