Hi Kamal,
Thanks for the reply. I'm very new to this, and have limited understanding as of yet. Where does this stuff belong (in the aspx.cs?) and where does the onKeyUp="ToUpper(this)" go? Thanks a lot,
jfh

<script language="JavaScript">
<!--
// How to Call: onKeyUp="ToUpper(this)"
function ToUpper(oObject) {
    oObject.value = oObject.value.toUpperCase();
}
//-->
</script>
