Something to keep in mind is that expanding is not the same as selecting a
node. By default, a node that is selected can also fire an expanded event.
Expanding a node therefore doesn't necessarily select it. You have to
capture the Expand event with your own handler. Let's say we had a tree
named objTree. Capturing the node that was expanded may look something like
this:

private void objTree_Expand(object sender, TreeViewClickEventArgs e)
{
    TreeNode objNode = (TreeNode)e.Node;
    string strIndex = objNode.GetNodeIndex();
}

You could probably even set the current index to equal the expanded node.

        Hope this helps,
