You can do this by using Jquery.

Not tested with the actual data, but hope this should work for you.

 $(function () {
        $('#CheckBox2').change(function () {
            $("#TextBox1").val(($(this).is(':checked')) ? "1" : "0");
        });
    });

Also you must need to add jquery plugin right before the javascript code which I gaved u. Below is one of the plugin which you can use

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>

Do let us know if it works or not
