enable/disable radiobuttonlist with javascript
<p>I am trying to enable/disable radiobuttonlist with javascript code. This javascript is working fine with textboxes but it looks like that it doesn't work with radiobuttonlist.
Here is the code I am using:</p>

<pre><code> var chkEPM = document.getElementById("&lt;%=chkEPM.ClientID %&gt;");
        chkEPM.onchange = function () {
            if (this.checked == true)
                document.getElementById("&lt;%=rblEPM.ClientID %&gt;").disabled = false;
            else
                document.getElementById("&lt;%=rblEPM.ClientID %&gt;").disabled = true;
        };
</code></pre>

<p>Thanks in advance for each reply and have a good day/night</p>
