How to retain scrool position in tree view after postback

I have been looking for an elegant solution to this problem for a while here is the cleanest one I have found so far:

///

/// Handles the click event when a tree node is selected
///

/// treeview reference
///
protected void TreeView_SelectedNodeChanged(object sender, EventArgs e)
{
// Cast the sender to a treeview
TreeView T = sender as TreeView;
//Execute required code
//Finally register the start of JScript to load to selected treeview
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "selectNode", "var elem = document.getElementById('" + T.ClientID + "_SelectedNode');var node = document.getElementById(elem.value);node.scrollIntoView(true);elem.scrollLeft=0;", true);
}
