I have the following tree:

```
Animals
 |
 |___Zebra
 |    |__Head
 |    |__Arms
 |    |__Legs
 |   
 |___Monkey
      |__Head
      |__Arms
      |__Legs

```

Each animal has an ID number stored in the Tag field and their name is in Name field of node.I want to press a button that says "Sort by ID" and have the "Zebra" above turn into "14" etc, and then resort numerically. However, I want the children to stay with the head, arms, legs order. When I use the following code, it works, but it also re-sorts the head arms legs into arms, head, legs. I've tried a NodeSorter, but I just didn't get any different results. I'm also very new to C# so I might have implemented it incorrectly. :) I'm also using a custom node with a few extra fields to store data and boolean values. That's what the "JacksNode" refers to below.

Here's the code:

```
public static void sortByAnimalID(TreeView tv)
    {
        tv.BeginUpdate();
        foreach (TreeNode treeNode in tv.Nodes[0].Nodes)
        {
            if (((JacksNode)treeNode).IsAnimal)
            {
                treeNode.Text = Convert.ToString(treeNode.Tag);
                treeNode.Name = Convert.ToString(treeNode.Tag);
            }
        }
        tv.Sort();
        tv.EndUpdate();
    }

```

Any ideas on what I'm doing wrong? I've searched the web for two weeks and have been overwhelmed with all the treeview articles. However, none have been this specific.
Thanks guys/gals for any suggestions.
