DevExpress 中根据数据库字典动态生成卡式菜单 z

第三方的Devexpress套件由于要使用权限机制控制不一样用户进入系统显示菜单因此要配合字典数据动态生成。在WEB中这种问题灰常的轻松在winform里就稍微有点不一样为了用DEV实现卡式菜单有组的概念具体如图红色部分

提示：这里用了菜单头、菜单组、菜单项来逐级生成 ，首先是菜单头便利建立而后判断是否有菜单组若是有菜单组就先生成菜单组而后把菜单项加入菜单组最后为按钮注册事件，这里的事情用一个公用方法搞定便可

/// <summary>
        /// 动态加载菜单
        /// </summary>
        private void GetMenuBind()
        {
            //根据登陆用户角色菜单动态建立
            //循环建立卡菜单
            DataTable baseModuleDT = BLL.BaseModule.GetDataTable("LevelNo=1", "");
            for (int i = 0; i < baseModuleDT.Rows.Count; i++)
            {
                //建立卡
                RibbonPage ribbonPage = new DevExpress.XtraBars.Ribbon.RibbonPage();//菜单卡对象定义
                ribbonPage.Text = baseModuleDT.Rows[i]["FullName"].ToString();
                this.ribbon.Pages.Add(ribbonPage);

                //获取组菜单

动态调用事件以下：

/// <summary>
        /// 动态调出窗体事件 注：动态调用窗体名需和数据库中名称彻底一致
        /// </summary>
        private void barButtonItem_ItemClick(object sender, ItemClickEventArgs e)
        {
            
            if (!ShowChildrenForm(e.Item.Tag.ToString()))
            {
                if (this.MdiChildren.Length < childFormMaxNumber)
                {
                    DictItemUtil.AddLog("成功打开" + e.Item.Caption.ToString());  
                    Assembly asm = Assembly.Load("MemberManager");//程序集名
                    object frmObj = asm.CreateInstance("MemberManager." + e.Item.Tag.ToString());//程序集+form的类名。
                    Form childForm = (Form)frmObj;
                    childForm.Tag = e.Item.Tag.ToString();  //tag属性要从新写一次，不然在第二次的时候取不到。缘由还不清楚。有知道的望告知。
                    childForm.MdiParent = this;
                    childForm.Show();
                }
                else
                    MessageUtil.ShowWarning(message);
            }
