U can use this validation
function isNumberKey(evt)
{
var charCode = (evt.which) ? evt.which : event.keyCode
if (charCode > 31 && (charCode < 48 || charCode > 57))
return false;
return true;
}
<asp:TextBox ID="txtra" runat="server" CssClass="ddddd" onkeypress="return isNumberKey(event)">
function isNumberKey(evt)
{
var charCode = (evt.which) ? evt.which : event.keyCode
if (charCode > 31 && (charCode < 48 || charCode > 57))
return false;
return true;
}
<asp:TextBox ID="txtra" runat="server" CssClass="ddddd" onkeypress="return isNumberKey(event)">

Use keyup or keypress event
$("#txtQty").keyup(function() {
var $this = $(this);
$this.val($this.val().replace(/[^\d.]/g, ''));
});
or
<html>
<head>
<script language="Javascript">
<!--
function isNumberKey(evt)
{
var charCode = (evt.which) ? evt.which : event.keyCode
if (charCode != 46 && charCode > 31
&& (charCode < 48 || charCode > 57))
return false;
return true;
}
//-->
</script>
</head>
<body>
<input id="txtChar" onkeypress="return isNumberKey(event)">
type="text" name="txtChar">
</input></body>

Aman Gandhi
i am using below code.
function fn_allowDecimal(s, e) {
var searchSpecial = '$Backspace$Del$Home$Tab$Left$Right$Up$Down$End$';
if (searchSpecial.indexOf('$' + e.htmlEvent.key + '$') < 0) {
var theEvent = e.htmlEvent || window.event;
var key = theEvent.keyCode || theEvent.which;
key = String.fromCharCode(key);
var regex = /[0-9 .]/;
if (!regex.test(key)) {
theEvent.returnValue = false;
if (theEvent.preventDefault)
theEvent.preventDefault();
}
}
}
Thats code is working for me in some manner but user can enter decimal point "." multiple times.
how can i avoid that

Hi,
Apart from the above two, you can do it using AJAX by using AJAX Filtered TextBox control.
Try this one, it is simple and easy to handle..
