I try to make a combination of 2 of your articles

It works but the column header width's are not matching the data columns.

When i take out the nested gridview it works fine.

Here's my code:

 <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
$("[src*=plus]").live("click", function () {
$(this).closest("tr").after("<tr><td></td><td colspan = '999'>" + $(this).next().html() + "</td></tr>")
$(this).attr("src", "images/minus.png");

[code]....
