hi rajasekar,
i did not understand your question propally, anyway try this, are you want to disable a text box? what you mean HTML fields?
<body>
<script language='javascript'>
function disablenow(){
document.getElementById('T1').disabled=true
}
</script>
<form method="POST">
<input type="text" id="T1" name="T1" size="20">
<input type="radio" value="V1" onclick="javascript
:disablenow()" name="R1"></p>
</form>
</body>
