Hi,

I have 3 radio buttons on my page with different IDs, but they are grouped
with name "Q1".

I need to add some kind of validator on them so that user must have to
select one of them.

I cannot use radiobuttonlist, its because these 3 radiobuttons have to be
placed in seperate table cells.

Could anyone help me on how i can acheive this?

Thanks in advance.

there a number of ways to do this. use getElementsByTagName, and checking the
name, but the simplest is to add the checkbox id to the validator

ClientScript.RegisterExpandoAttribute(myValidator.ClientID,
"chk1",checkbox1.ClientID);
ClientScript.RegisterExpandoAttribute(myValidator.ClientID,
"chk2",checkbox2.ClientID);
ClientScript.RegisterExpandoAttribute(myValidator.ClientID,
"chk2",checkbox2.ClientID);

then in the client validation function:

function chkValid(oSrc, args)
{
var chk1 = document.getElementById(oSrc.chk1);
var chk2 = document.getElementById(oSrc.chk2);
var chk3 = document.getElementById(oSrc.chk3);
}
