How can i make in treeView1 in TreeNode EnsureVisible() that it will show the top first child node and not the bottom as first ?

In this method i'm doing a search in a TreeNodes:

private void FindByText()
        {
            TreeNodeCollection nodes = treeView1.Nodes;
            foreach (TreeNode n in nodes)
            {
                FindRecursive(n);
            }
        }

And the FindRecursive:

private void FindRecursive(TreeNode treeNode)
        {
            foreach (TreeNode tn in treeNode.Nodes)
            {
                string result = Regex.Replace(tn.Text, @"^\d*\.\s*", string.Empty);
                if (tn.Text.Contains(this.txtNodeTextSearch.Text))
                {
                    tn.BackColor = Color.Yellow;
                    tn.EnsureVisible();
                    count++;
                    label11.Text = count.ToString();
                }

                FindRecursive(tn);
            }
        }

In the FindRecursive method i did:

tn.EnsureVisible();

But if for example i searched and it found 20 items it will scroll down and show me the last found item. Then i will need to scorll up to see the other items it found.

I need that it will make like tn.EnsureVisible(); but will point on the top first item and if i will like i will scroll down to see the others.
