If you want to try jQuery and delete using asp.net in general to help separate the concepts or technologies that you are learning, you can simply use jQuery with html to have a page with a menu that is "without postback" loaded into the content .. .
index.html
<html>
<head>
<title>A website</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
$(".navigation a").click(function() {
$("#content").load($(this).attr("href"));
return false;
});
});
</script>
</head>
<body>
<ul class="navigation">
<li><a href="content-1.html">Content 1</a></li>
<li><a href="content-2.html">Content 2</a></li>
<li><a href="content-3.html">Content 3</a></li>
</ul>
<div id="content">
</div>
</body>
</html>
content-1.html
<h1>Content 1</h1>
<p>Hello there...</p>
content-2.html
<h1>Content 2</h1>
<p>etc etc etc</p>
and then you can just create sample html pages (insert two extremely simple pages) and the content will be loaded into your div ... and from there you can clearly deploy many ways!
