To expand a parent at a time on click event, you can try the following code:

protected void tvMenu_SelectedNodeChanged(object sender, EventArgs e)
{
    TreeNode tn = tvMenu.SelectedNode;
    tn.ExpandAll();
}

Well, for the root node of the tree, you would do it like this:

TreeView1.CollapseAll();
TreeView1.Nodes[0].Expand();
