Try with Javascript
function isAlphaKey(evt)
{
var charCode = (evt.which) ? evt.which : event.keyCode
if (charCode > 31 && (charCode < 65 || charCode > 90) && (charCode < 97 || charCode > 122))
return false;
return true;
}

<script language="javascript">
function validate()
{
var iChars = "!@#$%^&*()+=-[]\\\';,./{}|\":<>?"+" ";//" " used to avoid space
for (var i = 0; i < document.formname.fieldname.value.length; i++)
{
if (iChars.indexOf(document.formname.fieldname.value.charAt(i)) != -1)
{
alert ("Your username has special characters. \nThese are not allowed.\n Please remove them and try again.");
return false;
}
else
{
return true;
}
}
}
</script>
U just place what ever characters u want to avoid in "iChars" field
Regards,
Harini
