Using Asp.net Webforms how can I validate that a checkbox has been checked. (I cannot do a postback) has to be in javascript (either custom - working with the existing validation controls for other fields. or using a .net validation control)

I have the following problem...
I'm developing an an asp.net 2 application in c#. This site is being built with accessibility in mind, and as such I need a to build a registration from that validates using server side scripts and
not use client side validation.I need to validate a textbox (whether any text has been entered), if a check box has been checked.
Bear in mind that I can't use any clientside code such as javascript postback that is wired into the <asp:CheckBox /> control.
<div class="subHead">Stock Options</div>
<table class="settingTable">
<tr>
<td colspan="2"><b>Limited Stock</b></td>
</tr>
[Code]....
How do I make it so that the validator for the stock count wont run unless the limited stock checkbox is checked?
ASP.NET3.5 Webforms. Am trying to put a validator on the drop down list, only if the checkbox is checked.

<script language="javascript" type="text/javascript">
function setVal(sender) {
var myVal = document.getElementById('<%=(DropDownList)CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("ddlSupplierCouncilArea")%>');

Even though im checking the checkbox im not the checkbox checked in code behind.
I have a CheckBox field inside a Formview.
<asp:FormView ID="_fvApplicant" runat="server" DefaultMode="Edit" OnItemDeleting="ApplicantItemDeleting" Width="100%" DataSourceID="_dsApplicant" ondatabound="ApplicantFormBound">
<asp:CheckBox ID="_chkSuitable" OnCheckedChanged="test" AutoPostBack="true" CausesValidation="true" runat="server" Checked='<%# Bind("Suitable") %>' /></td>
In my Code Behind in test method I am trying to set the checked to true, but in the ApplicantFormBound event when i debug it is never true...any reasons why? Basically I want to set the Validator to true when checked.
protected void test(object sender, EventArgs e)
{
CheckBox vld = (CheckBox)_fvApplicant.FindControl("_chkSuitable");
vld.Checked = true;
_fvApplicant.DataBind();
}
protected void ApplicantFormBound(object sender, EventArgs e)
{
var chk = (CheckBox)_fvApplicant.FindControl("_chkSuitable");
if (chk != null)

I want to reach checked rows item in ASP.Net Listview control.
For example:
if 3 Lines of Listview checked, I want to reach checked items value in listview.
I am using the AJAX ReorderList, and inside the ItemTemplate I have a label and a checkbox. Now when in firefox I am able to change the checkbox checked state, but in IE it won't allow me to do anything with it. Its weird because the checkbox becomes that blue colour like when it gets focus, but it won't put the check in it or call the postback. The ReorderList is inside an UpdatePanel, so that I can monitor when the check changes on its postback. Below is the code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<table>
<tr>
<td colspan="2">
