How to get hidden field value when check box is checked in a repeater controller?
<p>I have asp.net repeater controller and I am trying to get the value of a hidden field when <code>CheckBox1_CheckedChanged</code></p>

<pre><code>&lt;ul id="sortable"&gt;
    &lt;asp:Repeater runat="server" ID="rep_sortable"&gt;
        &lt;ItemTemplate&gt;
            &lt;li class="ui-state-default"&gt;
               &lt;span class="ui-icon ui-icon-arrowthick-2-n-s"&gt;&lt;/span&gt;
               &lt;%# DataBinder.Eval(Container.DataItem, "Body") %&gt; 
               &lt;%# DataBinder.Eval(Container.DataItem, "Completed") %&gt; 
               &lt;asp:CheckBox ID="chb_com"  runat="server" AutoPostBack="True" Checked='&lt;%# DataBinder.Eval(Container.DataItem, "Completed")  %&gt;' oncheckedchanged="CheckBox1_CheckedChanged"/&gt;
               &lt;asp:HiddenField ID="hf_reminderID" runat="server" Value='&lt;%# DataBinder.Eval(Container.DataItem, "ReminderID")  %&gt;'/&gt;
            &lt;/li&gt;
        &lt;/ItemTemplate&gt;
    &lt;/asp:Repeater&gt;
&lt;/ul&gt;
</code></pre>

<p>c#</p>

<pre><code>protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
   foreach()
}
</code></pre>
