I don't know of any examples. Everything I've seen on MSDN were examples of hooking the treeview up to a .sitemap, but then I wasn't looking for a database hookup either. I'd start there, and see if they have an example of hooking a treeview up to a sqldatasource.

        <asp:TreeView ID="tv" runat="server" />

        if (!IsPostBack)
        {

            TreeNode n1 = new TreeNode("Node 1");
            tv.Nodes.Add(n1);

            TreeNode n2 = new TreeNode("Node 2");
            tv.Nodes.Add(n2);

            TreeNode n3 = new TreeNode("Node 3");
            tv.Nodes.Add(n3);

            TreeNode n1_1 = new TreeNode("Node 1.1");
            n1.ChildNodes.Add(n1_1);

        }

Also:

A treeview will bind to a hierarchical datasource. An XmlDataSource is a hierarchical datasource, as is a sitemap datasource.

If you google around you will be able to find implementations of other hierarchical datasources which can convert a table (table datasource) to a hierarchical datasource given parent/child relationships.
