CustomValidator for Radio Button

[Ricky Williams]

I have a CustomValidator for a Radio Button that works fine with IE, but
doesn't trigger with Firefox or Netscape.

I have been stuck on this one for 3 weeks; any suggestions greatly
appreciated.

Thanks!

<script language="javascript">
function ValidateRadiobutton(oSrc, args) {
if(document.getElementById("<%=rbChoiceA.ClientID%>").checked == false
&&
document.getElementById("<%=rbChoiceB.ClientID%>").checked ==
false){
args.IsValid = false;
}
}
</script>

<asp:CustomValidator id="vld1PaymentType"
ClientValidationFunction="ValidateRadiobutton" runat="server"
ErrorMessage="Payment Type must be selected"
CssClass="ValidationMessage"></asp:CustomValidator>

Hi Ricky,

The ASP.NET 1.x validators do not support client-side validation on anything
but DHTML browsers (IE and IE/Mac). *always* create validation on the server
side to handle cases where the browser doesn't get supported or has
javascript turned off.

ASP.NET 2.0 and my Professional Validation And More
(http://www.peterblum.com/vam/home.aspx) both support client-side validation
on more browsers than the original ASP.NET 1.x validators.
In my Professional Validation And More, there are 25 validators including
those that can detect the rules you've described below (use my
CheckStateValidator and MultiConditionValidator).
