動态添加navBarControl1 DXperience學習筆記

在進行DXperience進行項目開發的時候 navBarControl1 提供了組分類的功能 相對于微軟自帶的控件 本人認為DXperience有着不可超越的優勢，在平常學習的過程中，碰到了一些問題 如何對navBarGroup1進行有選擇的顯示 即對于每個登入的使用者進行權限配置設定，今天把學習的經驗寫出來，希望能給DXperience愛好的初學者一點啟發

   資料庫讀取到 dataset後進行編寫如下代碼

以下是代碼片段： if (ds.Tables[0].Rows.Count > 0)                 {                     for (int i = 0; i < ds.Tables[0].Rows.Count; i++)                     {                          string id = ds.Tables[0].Rows[i]["id"].ToString();  //該使用者可管理的id号                          if (User.Power.IndexOf(id) == -1)                              continue;                         string mid = ds.Tables[0].Rows[i]["mid"].ToString(); //隸屬的管理類型                         string name = ds.Tables[0].Rows[i]["PowerName"].ToString(); //管理名稱                         int cls = int.Parse(ds.Tables[0].Rows[i]["type"].ToString());//圖檔号碼                         switch (mid)                         {                             case "1":                                 AddGroup(navBarGroup1, name, "n" + id, cls);//AddGroup函數用于在navBarGroup1控件中寫入新項                                 break;                             case "2":                                 AddGroup(navBarGroup2, name, "n" + id, cls);                                 break;                             case "3":                                 AddGroup(navBarGroup3, name, "n" + id, cls);                                 break;                             case "4":                                 AddGroup(navBarGroup4, name, "n" + id, cls);                                 break;                             case "5":                                 AddGroup(navBarGroup5, name, "n" + id, cls);                                 break;                         }                     }                 }

以下是 AddGroup  函數

以下是代碼片段：  /// <summary>         /// 參數傳遞 添加控件         /// </summary>         /// <param name="nbg"></param>         /// <param name="name"></param>         /// <param name="id"></param>         /// <param name="cls"></param>         private void AddGroup(DevExpress.XtraNavBar.NavBarGroup nbg,string name,string id,int cls )         {             try             {                 DevExpress.XtraNavBar.NavBarItem navBarItem1 = new DevExpress.XtraNavBar.NavBarItem();                 navBarItem1.Caption = name;                 navBarItem1.Name = id;                 navBarItem1.SmallImageIndex = cls;                 navBarItem1.LinkClicked += new DevExpress.XtraNavBar.NavBarLinkEventHandler(navBarItem1_LinkClicked);  //新增項的 點選事件 觸發                 nbg.ItemLinks.AddRange(new DevExpress.XtraNavBar.NavBarItemLink[] { new DevExpress.XtraNavBar.NavBarItemLink(navBarItem1) });             }             catch (Exception ex)             {                MessageBox.Show(ex.Message);             }         }

以下是點選事件代碼

以下是代碼片段： /// <summary>         /// 左側欄點選事件         /// </summary>         /// <param name="sender"></param>         /// <param name="e"></param>         private void navBarItem1_LinkClicked(object sender, DevExpress.XtraNavBar.NavBarLinkEventArgs e)         {             try             {                 string pagename = e.Link.Item.Name; //擷取左側欄的name值                 string caption = e.Link.Caption;    //擷取名字                 switch (pagename)                     {                         case " ":                                 //執行代碼                            break;                      }            }             catch (Exception ex)             {                MessageBox.Show(ex.Message);             }         }
