How to get a child control from a Tr?
<p>I have a hidden field in each <code>Tr</code> in my template:</p>

<pre><code>&lt;ItemTemplate&gt;
    &lt;tr style="" class="ui-selectee trClass ui-widget-content"&gt;
        &lt;td style="width: 100px"&gt;
            &lt;asp:HiddenField ID="idField" runat="server" Value='&lt;%# Eval("Id") %&gt;' /&gt;
            &lt;asp:Label ID="IdLabel" runat="server" Text='&lt;%# Eval("Id") %&gt;' /&gt;
        &lt;/td&gt;
        &lt;td&gt;
            &lt;asp:Label ID="NameLabel" runat="server" Text='&lt;%# Eval("Name") %&gt;' /&gt;
        &lt;/td&gt;
        &lt;td&gt;
            &lt;asp:Label ID="EmailLabel" runat="server" Text='&lt;%# Eval("Email") %&gt;' /&gt;
        &lt;/td&gt;
    &lt;/tr&gt;
&lt;/ItemTemplate&gt;
</code></pre>

<p>No, in the <code>each</code> loop on the selected <code>Tr</code>, how can I get the hidden field ?</p>

<pre><code>$(".ui-selected", this).each(function () {
    var index = $(".selectable tr").index(this);

    var idField = ??
});
</code></pre>

<p>I've already started with:</p>

<pre><code>var idField = $(".selectable tr &gt; [id*='idField']");
</code></pre>

<p>But seems it does not work!</p>

<p>Any help!</p>
