    I do something like this in php, I don't know if this is what you mean?

    PHP Code:
    function php_navigation($nav_page$page_set) {
    // Format for php_navigation 
            // <ul>
            //    <li><a href="{link}">Name of Link</a></li>
            // </ul>
    global $db;        
    $query "SELECT id, blog_name FROM pages ORDER BY new_blog_date ASC LIMIT 25";
    $output "<ul>";
            if (
    $result mysqli_query($db$query)) {
                while (
    $page mysqli_fetch_array($result)) {
    $output .= "<li><a href=\"" $nav_page "?page=" urlencode($page["id"]) . "\">";
                   if (
    $page_set == $page['id']) {
    $output .= "<span class=\"selected\" >{$page["blog_name"]}</span>";       
                   } else {
    $output .= "{$page["blog_name"]}";
    $output .= "</a></li>";               
    /* free result set */
    $output .= "</ul>";

    If you're working in ASP.NET, you can put a menu control, and write the query as a stored procedure then stick a datasource on the page and hook them all up. For menus like this that are unlikely to change frequently but appear on all pages, you should also use caching, which can easily be turned on in the control in .net. If you're serving 10,000 pages per day, you don't want to be making 10,000 round trips to the db to get exactly the same data when you can do just one.
