动态创建的树，给树节点绑定nodecommand事件无效

foreverjjj

如题，做了个实验，发现无效，是不是我代码哪里不对
        Tree tree = new Tree();
        tree.NodeCommand += new EventHandler<TreeCommandEventArgs>(Tree1_NodeCommand);
        FineUI.TreeNode tn = new FineUI.TreeNode();
        tn.EnablePostBack = true;
        tn.Text = "123";
        tree.Nodes.Add(tn);
        tree.NodeCommand += new EventHandler<TreeCommandEventArgs>(Tree1_NodeCommand);
        ContentPanel1.Controls.Add(tree);
