Solution 1

Try this

JavaScript

$(document).ready(function()
{
var qtytxt='<%=TxtAtQuantityBNW.ClientID%>';
var amounttxt='<%=LblATTotalAmntBNW.ClientID%>';
var pricetxt='<%=LblATUPriceBNW.ClientID%>';
$('#qtytxt').focusout(function()
{
$('#amounttxt').val()=$('#qtytxt').val()*$('#pricetxt').val();
});
});

Hope this helps
