Confirm client side RadioButtonGroup

<asp:RadioButton GroupName="EndorsementType" runat="server" ID="rdoAddProperty" Text="Add Property to TIV" />
<asp:RadioButton GroupName="EndorsementType" runat="server" ID="rdoRemoveProperty" Text="Remove Property from TIV" />
<asp:RadioButton GroupName="EndorsementType" runat="server" ID="rdoChangeProperty" Text="Change Property Values" />

I was thinking about implementing a custom validator

and using a client function JavaScript

to reference the RadioButton ID (I am using web forms, not mvc),

something like.. 
 if(document.getElementById(<%= rdoAddProperty.ClientId %>).checked == true) && ...

Does anyone know a way to do this without knowing the clientId?

If your radios are contained in something like a DIV, and because your asp: RadioButtons will appear as HTML inputs, you can do something like:



<script type="text/javascript" language="javascript">
    function Validate()
    {
        var l_elemsRadios = document.getElementById("MyRadios").getElementsByTagName("input");

        if (l_elemsRadios == null)
            return;

        for (var i = 0; i < l_elemsRadios; i++)
        {
            // validate l_elemsRadios[i] through l_elemsRadios[n]
        }
    }
</script>


<div id="MyRadios">
    <input type="radio" name="EndorsementType" value="Remove Property from TIV" >Remove Property from TIV
    .
    .
    .
</div>

You will need to put your client ID in the form, as with INamingContainer your ID can change in relation to other information stored on the server.
