标题: 如何设置带有权限的树控件？
例如：管理员，展示所有的树节点
某用户：没有某树节点的权限不显示
请教一下？怎么做

读取相应的数据源，用递归的方法添加treeNode。

也是我看了官方的动态添加菜单

使用不同的xml读取就行了

两种方式都可以，如果需要控制到具体的某个TreeNode节点的话，还是 zy32002 说的正确。

AppBox首页的菜单树，就是从数据库中读取后应用权限，然后递归生成 TreeNode 集合

发个我的代码供楼主参考
前台：

      /// <summary>
      /// 树型菜单
      /// </summary>
      /// <returns></returns>
      private FineUI.Tree GetTree(Guid rootId)
      {
         AccountEntity Me = Session["Account"] as AccountEntity;
         FineUI.Tree tree = new Tree();
         tree.AutoScroll = true;
         tree.EnableArrows = true;
         tree.EnableLines = false;
         tree.ShowBorder = false;
         tree.ShowHeader = false;
         //动态加载下级节点
         tree.AutoLeafIdentification = false;
         tree.NodeLazyLoad += Tree_NodeLazyLoad;

         //获取一级节点
         Menus menuBll = new Menus();
         bll.Roles bll = new abcebiz.bll.Roles();
         Collection<RolesViewEntity> roles = bll.SelectRolesByParentId(rootId, Me.GroupId);
         foreach (RolesViewEntity ro in roles)
         {
            FineUI.TreeNode node = new FineUI.TreeNode();
            node.Text = ro.Name;
            node.NodeID = ro.MenuId.ToString();
            if (menuBll.SelectByParentId(ro.MenuId).Count > 0)
            {
                  node.Leaf = false;

            }

                  //node.OnClientClick = mainTabStrip.GetAddTabReference(menu.Name, menu.URL, menu.Name, true);
            }
            tree.Nodes.Add(node);
         }
         return tree;
      }

      /// <summary>

      private void Tree_NodeLazyLoad(object sender, FineUI.TreeNodeEventArgs e)
      {
         AccountEntity Me = Session["Account"] as AccountEntity;
         e.Node.Expanded = true;
         Menus menuBll = new Menus();
         Guid ParentId = ValidateHelper.GetNullableGuid(e.NodeID);
         bll.Roles bll = new abcebiz.bll.Roles();
         Collection<RolesViewEntity> roles = bll.SelectRolesByParentId(ParentId, Me.GroupId);
         foreach (RolesViewEntity ro in roles)

            }
            else

                  node.Leaf = true;
                  //node.OnClientClick = mainTabStrip.GetAddTabReference(menu.Name, menu.URL, menu.Name, true);
                  node.NavigateUrl = ro.URL;

            }
            e.Node.Nodes.Add(node);
         }
      }

BLL:
      /// <summary>

      public virtual Collection<RolesViewEntity> SelectRolesByParentId(Guid ParentId, Guid GroupId)
      {
         return dal.SelectRolesByParentId(ParentId, GroupId);
      }

DAL:
      public virtual Collection<RolesViewEntity> SelectRolesByParentId(Guid ParentId, Guid GroupId)
      {
         string sql = @"
SELECT *

[RolesView]

[AccountGroupId] = @AccountGroupId
AND

AND
[visible]=1

";

         SqlParameter[] args = new SqlParameter[]
{
            Parameter.Menus.ParentId,
Parameter.Roles.AccountGroupId

};
         args[0].Value = ParentId;
         args[1].Value = GroupId;

         return RolesViewEntity.FillCollection(SqlHelper.ExecuteReader(CommandType.Text, sql, args));
      }

SQL SERVER做个视图，把MENUS跟ROLES做到一起
