<p><b><a href="http://jsfiddle.net/FRdAz/1/" rel="nofollow">Working jsFiddle Demo</a></b></p> <p>Your markup is so complex. So, the best way to make a relation between your <strong>parents</strong> and <strong>childs</strong> is using <strong>attributes</strong> instead of hierarchy of your HTML.</p> <p>Consider the following markup:</p> <pre><code><div><input type="checkbox" data-rel="parent" data-id="1" />Parent 1</div> <div> <div><input type="checkbox" data-rel="child" data-id="1" />Child 1.1</div> <div><input type="checkbox" data-rel="child" data-id="1" />Child 1.2</div> <div><input type="checkbox" data-rel="child" data-id="1" />Child 1.3</div> <div><input type="checkbox" data-rel="child" data-id="1" />Child 1.4</div> </div> <div><input type="checkbox" data-rel="parent" data-id="2" />Parent 2</div> <div> <div><input type="checkbox" data-rel="child" data-id="2" />Child 2.1</div> <div><input type="checkbox" data-rel="child" data-id="2" />Child 2.2</div> <div><input type="checkbox" data-rel="child" data-id="2" />Child 2.3</div> <div><input type="checkbox" data-rel="child" data-id="2" />Child 2.4</div> </div> </code></pre> <p>As you can see, I make a relation between parents and child with <code>data-rel</code> and <code>data-id</code> attributes.</p> <p>Then in your jQuery code:</p> <pre><code>$(document).ready(function () { // whenever the parent checkbox changed $(':checkbox[data-rel="parent"]').on('change', function () { // get the current group by data-id attribute var id = $(this).attr('data-id'); // get childs checkboxes within the current group $(':checkbox[data-rel="child"][data-id="' + id + '"]').prop('checked', this.checked); }); }); </code></pre> <hr /> <p><b><a href="http://jsfiddle.net/CRkJG/2/" rel="nofollow">Working jsFiddle Demo</a></b></p> <p>Because you said that you can't change your markup (as it's a controller in ASP.net), here is the solution to your markup:</p> <pre><code>$(function () { $('.tree').on('change', ':checkbox', function () { var checked = this.checked; var $elem = $(this).closest('table'); var depth = $elem.find('div').length; var $childs = $elem.nextAll('table'); $childs.each(function () { var $child = $(this); var d = $child.find('div').length; if (d <= depth) { return false; } $child.find(':checkbox').prop('checked', checked); }); }); }); </code></pre> <ul> <li><code>[!]</code> Don't forget to check the <a href="http://jsfiddle.net/CRkJG/2/" rel="nofollow">jsFiddle Demo</a>.</li> </ul>

1. COThe HTML in question, is rendered from a asp.net treeview control. And I don't think the attributes which you have used can be put in that control. I need a solution for the HTML that is rendered for me. Thanks.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
