10. <f:TwinTriggerBox ID="ttbxMyBox2" ShowLabel="false" OnTrigger1Click="ttbxMyBox2_Trigger1Click"
    
11. Trigger1Icon="Search" ShowTrigger2="false" EmptyText="新标题" Trigger2Icon="Date" runat="server">
    
12. </f:TwinTriggerBox>
    
13. <f:Tree ID="tree2" Width="350px" ShowHeader="true" Title="修改标题" EnableFrame="true" EnableCollapse="true"
    
14. runat="server">

16. </form>
    
17. －－－－－－－－－－－－－－－－
    
18. protected void yTreeItem(FineUI.Tree d, string Fs)
    
19. {
    
20. int i = 0;
    
21. FineUI.TreeNode N;
    
22. while (i < d.Nodes.Count)
    
23. {
    
24. N = d.Nodes[i];
    
25. N.Text = Fs+"-"+N.Text;
    
26. i++;
    
27. }
    
28. }
    
29. protected void ttbxMyBox2_Trigger1Click(object sender, EventArgs e)
    
30. {
    
31. tree2.Nodes.Clear();
    
32. foreach (FineUI.TreeNode N in tree1.Nodes)
    
33. {
    
34. tree2.Nodes.Add(N);
    
35. }
    
36. yTreeItem(tree2, ttbxMyBox2.Text);
    
37. }

修改Tree2的标题同时又修改了Tree1的标题，点解？只想修改Tree2的标题，不修改Tree1的标题。

是不是说得不明白？
首先复制Tree1到Tree2,然后修改Tree2的节点的标题。
