DevExpress 中根據數據庫字典動態生成卡式菜單

最近在寫HR系統用到的第三方的Devexpress套件因為要使用權限機制控制不同用戶進入系統顯示菜單所以要配合字典數據動態生成。在WEB中這種問題灰常的輕松在winform里就稍微有點不同為了用DEV實現卡式菜單有組的概念具體如圖紅色部分

提示：這里用了菜單頭、菜單組、菜單項來逐級生成 ，首先是菜單頭便利創建然后判斷是否有菜單組如果有菜單組就先生成菜單組然后把菜單項加入菜單組最后為按鈕注冊事件，這里的事情用一個公用方法搞定即可

        /// <summary>
        /// 動態加載菜單
        /// </summary>
        private void GetMenuBind()
        {
            //根據登錄用戶角色菜單動態創建
            //循環創建卡菜單
            DataTable baseModuleDT = BLL.BaseModule.GetDataTable("LevelNo=1", "");
            for (int i = 0; i < baseModuleDT.Rows.Count; i++)
            {
                //創建卡
                RibbonPage ribbonPage = new DevExpress.XtraBars.Ribbon.RibbonPage();//菜單卡對象定義
                ribbonPage.Text = baseModuleDT.Rows[i]["FullName"].ToString();
                this.ribbon.Pages.Add(ribbonPage);

                //獲取組菜單
                DataTable baseModuleDTG = BLL.BaseModule.GetDataTable("ParentId=" + baseModuleDT.Rows[i]["Id"].ToString() + " and LevelNo=2", "");
                if (baseModuleDTG.Rows.Count <= 0)
                {
                    //沒有組
                    RibbonPageGroup ribbonPageGroup = new DevExpress.XtraBars.Ribbon.RibbonPageGroup();//菜單卡分組定義
                    ribbonPageGroup.Text = baseModuleDT.Rows[i]["FullName"].ToString();//卡片組名
                    ribbonPage.Groups.Add(ribbonPageGroup);

動態調用事件如下：

        /// <summary>
        /// 動態調出窗體事件 注：動態調用窗體名需和數據庫中名稱完全一致
        /// </summary>
        private void barButtonItem_ItemClick(object sender, ItemClickEventArgs e)
        {
            
            if (!ShowChildrenForm(e.Item.Tag.ToString()))
            {
                if (this.MdiChildren.Length < childFormMaxNumber)
                {
                    DictItemUtil.AddLog("成功打開" + 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的類名。
                    Form childForm = (Form)frmObj;
                    childForm.Tag = e.Item.Tag.ToString();  //tag屬性要重新寫一次，否則在第二次的時候取不到。原因還不清楚。有知道的望告知。
                    childForm.MdiParent = this;
                    childForm.Show();
