Hi kevinf,
Use JavaScript to validate the TextBoxes. Assign a common class to each TextBox.
Then using the class selector check the value of the TextBox with in the range.
Check the example.
HTML
<html>
<head>
<meta charset="utf-8" />
<title></title>
</head>
<body>
<input type="text" class="validate" />
<input type="text" class="validate" />
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
$(function () {
$('.validate').change(function () {
var number = $(this).val();
if ((isNaN(number))) {
alert('Invalid number');
return false;
}
if (parseFloat(number) >= 0 && parseFloat(number) <= 999.99) {
return true;
} else {
alert('Enter number between 0 to 999.99');
return false;
}
});
});
</script>
</body>
</html>
