I have post the code for How to fire JavaScript and JQuery in Textbox Keypress event.

Client Side Code.

<html xmlns="">
<head runat="server">
<script language ="javascript" src="Scripts/jquery-1.4.1.js"></script>
<script language ="javascript" src="Scripts/jquery-1.4.1.min.js"></script>

<script type="text/javascript" language="javascript">
function validateNumbersOnly(e) {
var unicode = e.charCode ? e.charCode : e.keyCode;
if ((unicode == 8) || (unicode == 9) || (unicode > 47 && unicode < 58)) {
return true;
else {
window.alert("This field accepts only Numbers");
return false;

$(document).ready(function () {
$("#TextBox2").keypress(function () {
alert('Check this');


<form id="form1" runat="server">
Asp TextBox : <asp:TextBox ID="numericTextBox" runat="server" onkeypress="return validateNumbersOnly(event);"></asp:TextBox> <br />
