Customvalidator control - SetFocusOnError="True" not working for CheckboxList
<p>I am validating a checkbox list using custom validator and jquery to check required validation, its validating fine but its not getting focus on error. </p>

<p>the asp.net for CheckBoxList and CustomValidator is : </p>

<pre><code>&lt;asp:CheckBoxList ID="cblSellerCategories" 
 runat="server" 
 RepeatDirection="Horizontal"&gt; 
&lt;/asp:CheckBoxList&gt;


&lt;asp:CustomValidator ID="CustomValidator2" 
 runat="server"
 ClientValidationFunction="CheckSellerCategory"
 CssClass="errorBox" 
 ErrorMessage="Select seller type" 
 SetFocusOnError="True"&gt; 
&lt;/asp:CustomValidator&gt;
</code></pre>

<p>and Jquery is </p>

<pre><code>function CheckSellerCategory(sender, args) {
args.IsValid = false;
$("[id$='cblSellerCategories']").find(":checkbox").each(function () {
    if (jQuery(this).attr("checked")) {
        args.IsValid = true;
        return;
    }
});
}
</code></pre>

<p>How to get focus on error(if any check box is not selected). I tried with validation group as well but no luck.</p>
