    <p>Your javascript is throwing an error at src.endsWith("plus.png") because there is no built in endsWith function in js. replace that with src.substr(-8) == "plus.png" instead and it works:</p> <pre><code>&lt;script type="text/javascript"&gt; //master: id of div element that contains the information about master data //details: id of div element wrapping the details grid function showhide(master, detail) { //First child of master div is the image var src = $(master).children()[0].src; //Switch image from (+) to (-) or vice versa. if (src.substr(-8) == "plus.png") src = src.replace('plus.png', 'minus.png'); else src = src.replace('minus.png', 'plus.png'); //Set new image $(master).children()[0].src = src; //Toggle expand/collapse $(detail).slideToggle("normal"); } &lt;/script&gt; </code></pre> <p>EDIT - Working example:</p> <p><strong>MasterPage.master</strong></p> <pre><code>&lt;%@ Master Language="C#" AutoEventWireup="true" %&gt; &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head runat="server"&gt; &lt;title&gt;Untitled Page&lt;/title&gt; &lt;script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; //master: id of div element that contains the information about master data //details: id of div element wrapping the details grid function showhide(master, detail) { //First child of master div is the image var src = $(master).children()[0].src; //Switch image from (+) to (-) or vice versa. if (src.substr(-8) == "plus.png") src = src.replace('plus.png', 'minus.png'); else src = src.replace('minus.png', 'plus.png'); //Set new image $(master).children()[0].src = src; //Toggle expand/collapse $(detail).slideToggle("normal"); } &lt;/script&gt; &lt;asp:ContentPlaceHolder id="head" runat="server"&gt; &lt;/asp:ContentPlaceHolder&gt; &lt;/head&gt; &lt;body&gt; &lt;form id="form1" runat="server"&gt; &lt;div&gt; &lt;asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server"&gt; &lt;/asp:ContentPlaceHolder&gt; &lt;/div&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p><strong>Default2.aspx</strong></p> <pre><code>&lt;%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" Title="Untitled Page" %&gt; &lt;asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server"&gt; &lt;/asp:Content&gt; &lt;asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server"&gt; &lt;div class="searchgroup" id='master0' onclick='showhide("#master0","#detail0")'&gt; &lt;img id="ctl00_ContentPanel_gvMaster_ctl02_imgCollapsible" class="first" src="plus.png" style="border-width:0px;margin-right: 5px;" /&gt; &lt;span class="searchheader"&gt;ABC&lt;/span&gt; &lt;/div&gt; &lt;div id='detail0' class="searchdetail"&gt; &lt;div&gt; &lt;table class="searchgrid" id="ctl00_ContentPanel_gvMaster_ctl02_gvDtails"&gt; &lt;tr&gt; &lt;th&gt;Status&lt;/th&gt; &lt;/tr&gt; &lt;tr class="searchrow"&gt; &lt;td&gt;2&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/div&gt; &lt;/div&gt; &lt;/asp:Content&gt; </code></pre>

    1. COHow come I don't get this error when I don't use a master page. As soon as I put the script in the head section of the master page, showhide function does not fire and when I set breakpoints in firebug, it says undefined for everything

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
