David Waz... #2 Radio Button List server control and java script
The aspx control obviously renders as normal HTML. Use
the ID/Name of the html control as usual.
An easy way to get the HTML name:
htmlName=replace(RadioButtonControl.UniqueName,":" ,"_")

Hi
Example ( Should work... I did not check :) )
Replace FORMNAME/RADIONAME with yours
<html>
<head>
<script language="JavaScript">
function checkRadio(){
var bIsChecked = false;
var r = document.forms["myForm"].r1;
for(i=0;i<r.length;i++)
{
if( r[i].checked )
{
bIsChecked = true;
break;
}
}
if(!bIsChecked ) alert("Please check.... ");
return bIsChecked;
}
</script>
</head>
<body>
<form name="myForm">
<input type="radio" name="r1">
<input type="radio" name="r1">
<input type="radio" name="r1">
<input type="radio" name="r1">
<input type="radio" name="r1">
<input type="submit" onclick="return checkRadio()" value="Click to test
radio">
</form>
</body>
</html>
Note if for some reason the list has only 1 item the length will be
undefined.
And also we have a good group for client issues
microsoft.public.scripting.jscript
