treeview中节点url转向的问题

生成 TreeNode.NavigateUrl的时候生成为
TreeNode.NavigateUrl="message.aspx?id="+id;

您好，我在后台代码里添加 TreeNode.NavigateUrl="message.aspx?id="+id;这句的时候出现了以下错误，好象TreeNode没有NavigateUrl属性
CS0120: 非静态的字段、方法或属性“System.Web.UI.WebControls.TreeNode.NavigateUrl.get”要求对象引用

System.Web.UI.WebControls.TreeNode a = new System.Web.UI.WebControls.TreeNode();
a.NavigateUrl="message.aspx?id="+id;
root.ChildNodes.Add(a);

http://msdn2.microsoft.com/zh-cn/06bed2tx(VS.80).aspx

还是没有解决，我当前的aspx文件是这样的，不知道哪里有问题

net_lover(【孟子E章】) ( )偶像，他是那里人啊

root.ChildNodes.Add(a);
改为 TreeView1.Nodes.Add(a);
或者再加一句：TreeView1.Nodes.Add(root)试一试

在你初始化这颗树的时候就把 ID的值邦定在Node的NavigateUrl属性上就是NavigateUrl = "message.aspx?Node=" + ID;问题是你的treeview到底有没有节点阿

我是通过一个cs文件使treeview和数据库连接的，这个文件如下，有可以和这个有关

                                        AddNode(childNode, rootNode);
                                    }
                                }
                                childRead.Close();
                                AddNode(rootNode, SMNode);
                            }
                            conn.Close();
                        }
                        else
                        {
                            return null;
                        }
                    }
                }
                return SMNode;
            }
        }
    }
}

有可能是在这个文件里改，前面的javascript里的内容不用写

childNode = new SiteMapNode(this, childRead.GetInt32(0).ToString(), childRead.GetString(1), childRead.GetString(2), childRead.GetString(3)); NavigateUrl 对应的那个东东在处理一次就行了具体就是 childRead.GetString(n)+"Node="+childRead.GetString(0) 就行了试一试吧我不知道你是用SiteMapNode的那个资源邦定到 NavigateUrl上的

childRead.GetString(1)+"Node="+childRead.GetInt32(0)
这样就好了，谢谢柔石兄了！
