本来一行可以代替的树节点搜索

txtEditGroupCode.Text = TreeView1.SelectedNode.Text;

我用了递归。。。要多熟悉函数。。。。

 protected void TreeView2_SelectedNodeChanged(object sender, EventArgs e)
    {
        txtEditGroupCode.Text = TreeView2.SelectedNode.Text;

        foreach (TreeNode treenode in TreeView2.Nodes)
        {
            if (treenode.ChildNodes.Count != 0)
            {
                find(treenode);

            }
            else if (treenode.Selected == true)
            {
                txtEditGroupCode.Text = treenode.Value;
                TreeView2.Visible = false;
            }
            else
                continue;
        }
    }
    protected void find(TreeNode n)
    {
        foreach (TreeNode childnode in n.ChildNodes)
        {
            if (childnode.ChildNodes.Count != 0)
                find(childnode);
            else if (childnode.Selected == true)
            {
                txtEditGroupCode.Text = childnode.Value;
                TreeView2.Visible = false;
                //TreeView2.SelectedNode

            }
            else
                continue;
        }

    }
