And what about sum of checked cells in a column? What to use?

Yes I know. But I am new in javascript. Can you gave me an example for passing value of lbltotal to another page?

Can you gave me a example for add label valie in query string to the url in javascript?

I tried with javascript to get checked cells and it work, But won't pass to another page

I use this script

<script type="text/javascript">
$(function () {
$("input[type=checkbox]").change(function () {
var totalPrice = 0, ctlPrice;
$('#GridView1 tr').each(function () {
if ($(this).find('input:checkbox').attr("checked")) {
ctlPrice = $(this).find('[id$= lblListPrice]');
totalPrice += parseFloat(ctlPrice.text().replace(/[^\d\.]/g, ''));
}
});
$("#<%=GridView1.ClientID %> [id*=lblTotal]").text(totalPrice.toFixed(2));
});
});
</script>

How can i store lblTotal in querystring in js and pass to another page?

throught server side. Is it posible throught client side (JavaScript) and how?

Error message : CallTotal(int) : not all code paths return a value

it is show correctly in footer in lblTotal . But the value won't pass to another page :)

Code is good. This code is in Page1.aspx, I want to get lblTotal value and pass it in Label on Page2.aspx

this is my script for get checked cell sum in footer

<script type="text/javascript">
$(function () {
$("input[type=checkbox]").change(function () {
var totalPrice = 0, ctlPrice;
$('#GridView1 tr').each(function () {
if ($(this).find('input:checkbox').attr("checked")) {
ctlPrice = $(this).find('[id$= lblListPrice]');
totalPrice += parseFloat(ctlPrice.text().replace(/[^\d\.]/g, ''));
}
});
$("#<%=GridView1.ClientID %> [id*=lblTotal]").text(totalPrice.toFixed(2));
});
});
</script>
