Hi all,

I have a group of radio buttons. How do I check whether any of those radio buttons is not checked. The validation have to be done using VBscript.

Thanks in advance.

Is it server-side checking or client-side?
Server-side.
When you submit form to server all its parameters are sent to script.
If user didn't check any radio button you get empty value of parameter with same name as your radio button name.

E.g.
HTML:

<input type="radio" name="gender" value="male">Male
<input type="radio" name="gender" value="female">Female


Server script:
<%if request.Form("gender")="" then
'place your code here
end if
%>

or
<%if isEmpty(request.Form("gender")) then
'place your code here
end if
%>

choroque,

if you have 10 radio button,

Name all radio button same name, but different value

Sample:

<input type="checkbox" name="C1" value="ON1">
<input type="checkbox" name="C1" value="ON2">
<input type="checkbox" name="C1" value="ON3">

asp script:
i = 1
For Each Item in Request.Form("C1")
   IF Item.Value = "" Then Response.Write("C1.value = On" &i&" is no checked")
   i = i + 1
Next
