moving a treeview's scrollbars to the top of the treeview

I am trying to move the scrollbars of a treeview control to the top of the control.  When I add a large number of nodes and expand all the nodes via code, the treeview control moves to the bottom of the treeview.  I want the scrollbars to be at the top of the treeview.  I am pretty sure you can do this using the windows API SendMessage() function, but I dont know what values to give to the function to get it to work.  If there is a way to do it using c# code instead of the API call I would prefer to do that.

Thank You

Add the code below:

directoryTreeView.AfterExpand += new TreeViewEventHandler(directoryTreeView_AfterExpand);

private void directoryTreeView_AfterExpand(object sender, TreeViewEventArgs e)
{
     while(directoryTreeView.SelectedNode.Parent!=null)
     {
          directoryTreeView.SelectedNode = directoryTreeView.SelectedNode.Parent;
     }

     directoryTreeView.SelectedNode.EnsureVisible();
}

hope this is what you want..

Why not just:

if (myTreeView.Nodes.Count > 0)
  myTreeView.Nodes[0].EnsureVisible();
