动态添加权限navBarControl1设置 DXperience学习笔记



在进行DXperience进行项目开发的时候 navBarControl1 提供了组分类的功能 相对于微软自带的控件本人认为DXperience有着不可超越的优势，在平常学习的过程中，碰到了一些问题 如何对navBarGroup1进行有选择的显示即对于每个登录的用户进行权限分配，今天把学习的经验写出来，希望能给DXperience爱好的初学者一点启发

  数据库读取到 dataset后进行编写如下代码
 

以下是代码片段： 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();  //该用户可管理的id号                          if (User.Power.IndexOf(id) == -1)                              continue;                         string mid = ds.Tables[0].Rows[i]["mid"].ToString(); //隶属的管理类型                         string name = ds.Tables[0].Rows[i]["PowerName"].ToString(); //管理名称                         int cls = int.Parse(ds.Tables[0].Rows[i]["type"].ToString());//图片号码                          switch (mid)                         {                             case "1":                                 AddGroup(navBarGroup1, name, "n" + id, cls);//AddGroup函数用于在navBarGroup1控件中写入新项                                 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  函数

以下是代码片段：  ///         /// 参数传递 添加控件         ///         ///         ///         ///         ///         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);  //新增项的 点击事件 触发                 nbg.ItemLinks.AddRange(new DevExpress.XtraNavBar.NavBarItemLink[] { new DevExpress.XtraNavBar.NavBarItemLink(navBarItem1) });             }             catch (Exception ex)             {                MessageBox.Show(ex.Message);             }         }

以下是点击事件代码

以下是代码片段： ///         /// 左侧栏点击事件         ///         ///         ///         private void navBarItem1_LinkClicked(object sender, DevExpress.XtraNavBar.NavBarLinkEventArgs e)         {             try             {                 string pagename = e.Link.Item.Name; //获取左侧栏的name值                 string caption = e.Link.Caption;    //获取名字                 switch (pagename)                     {                         case " ":                                  //执行代码                            break;                      }            }             catch (Exception ex)             {                MessageBox.Show(ex.Message);             }                    }

Devexpress 之 NavBar 添加/删除

--添加新的ItemLink到 Active Group

int i = 0;

private void button1_Click(object sender, System.EventArgs e) {
    DevExpress.XtraNavBar.NavBarItem item = navBarControl1.Items.Add();
    item.LargeImageIndex = item.SmallImageIndex = imageComboBoxEdit1.SelectedIndex;
    item.Caption = "Item " + (i++).ToString();
    navBarControl1.ActiveGroup.ItemLinks.Add(item);
    ExistSelectedItemLink();
}

--删除当前所选ItemLink

private void button2_Click(object sender, System.EventArgs e) {
    if(navBarControl1.ActiveGroup.SelectedLink != null)
        navBarControl1.ActiveGroup.SelectedLink.Item.Dispose();
    ExistSelectedItemLink();
}

 

--改变样式

private void listBox1_SelectedIndexChanged(object sender, System.EventArgs e) {
navBarControl1.View = listBox1.SelectedItem as DevExpress.XtraNavBar.ViewInfo.BaseViewInfoRegistrator;
navBarControl1.ResetStyles();
}
