I’ve been using jQuery quite a bit lately.  I’ve grown very fond of it.  At the same time, I have been digging into ASP.NET AJAX 4.0.  I just read a post from Bertand Le Roy that made me smile.  In his post, he shows how you can do the following:

<ul class="dv">
    <li>{{ $dataItem }}</li>
</ul>
<script type="text/javascript">
   1:     $(".dv").dataView({ data: ["foo", "bar", "baz"] });
</script>

To me, being able to instantiate a DataView control using the jQuery plugin syntax is PRETTY COOL!  Check out the details of how all this works and download the sample at:
