showing tree node details separately in the same window

How can I show the details of a tree node, upon selection, in the same window but separately from the hierarchy tree.
So far I have successfully showed details in the treeview class using this code: 

  private void buttonCreateTree_Click(object sender, EventArgs e)
    {
        if (xd != null)
        {
            TreeNode rootNode = new TreeNode(xd.Root.FirstNode.ToString());
            AddNode(xd.Root, rootNode);
            treeView1.Nodes.Add(rootNode);

        }
        if (xd == null)
        {
            MessageBox.Show("No saved XML file!");

        }
    }

I've read about tags, but since I'm not very fond of Windows Forms, I don't know how to implement them correctly. What is the correct syntax for the solution? Update: The details of a tree node are its child components with custom attributes i made like creationDate, LastAccessDate and LastModifiedDate so it needs to show the child elements of a tree node in the same window but apart from the hierarchy tree? that doesn't even make sense O.o

Not sure if that is what you want, or for that matter if you are but you can play with this:

Add a Panel panel1 to the form and hook up this event:

private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{
    if (panel1.Controls.Count == 0)
    {
        panel1.Controls.Add(new TreeView());
        panel1.Controls[0].Dock = DockStyle.Fill;
    }
    TreeView tv = panel1.Controls[0] as TreeView;
    if (tv != null)
    {
        tv.Nodes.Clear();

        // option 1 deep copy:
        TreeNode tc = (TreeNode)e.Node.Clone();
        tv.Nodes.Add(tc);

        // option 2 shallow copy, 1 level
        TreeNode tn =  tv.Nodes.Add(e.Node.Text);
        foreach (TreeNode cn in e.Node.Nodes)
            tn.Nodes.Add(cn.Text);
    }
    tv.ExpandAll();
}

Do pick one of the two options and try..
