You can set value=true for any one radio button. So no need to validate. Anyway one radio button will be selected.

Radio button always must have to set the default properties to true just for one button.

As per my understanding, you want to validate in client side whether any one of the radio button is selected. If my understanding is correct, u can use the following code to validate in client side.

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ page errorPage="/wdk/errorhandler.jsp" %>
<%@ taglib uri="/WEB-INF/tlds/dmform_1_0.tld" prefix="dmf" %>

function buttonclick()

{

if(document.getElementById('radio1').checked || document.getElementById('radio2').checked){

//Place ur code here

alert("Valid");
} else {

                         //Place ur code here
                         alert("Select any one");
                   }

}

</script>
<webform/>
<body>

<dmf:form>
Enter Some Value

<dmf:panel name="mypanel">

<dmf:radio name="radio1" group="myradio" id="radio1"/>

<dmf:radio name="radio2" group="myradio" id="radio2"/>

</dmf:panel>

<dmf:button name="mybutton" label ='Test' onclick="buttonclick" runatclient='true'/>

</dmf:form>
</body>

</html>

- You can't validate a panel for required field.

<dmf:requiredfieldvalidator controltovalidate="mypanel" errormessage="non selected" name="myquirede"></dmf:requiredfieldvalidator>

Try giving controltovalidate='myradio', which is name of the group.

Thanks,
