    <script type="text/javascript" language="javascript">

    function enableTextBox()

    {

        if (document.getElementById("chkAssociation").checked == true)

            document.getElementById("txtAddress").disabled = false;

        else

            document.getElementById("txtAddress").disabled = true;

    }

    </script>
