asp hidden field not retaining values after postback

Hi.

I have a webpage (say W) that is displayed inside an iframe of a main page (say M) .

All the below events are in the webpage (W).

I calculate the gridview total using jquery and store it in a hidden variable.

I then take the value in code behind from this hidden variable for further calculations on button click.

This process works neatly when i run the webpage separately.

But when its inside the main page (M), the hidden fields do not retain their values and i get error.

jquery is as follows

function TotalTC() {

var txtTotal = 0;

$(".TCTotal").each(function () {

txtTotal += isNaN(parseFloat($(this).html())) ? 0 : parseFloat($(this).html());

});

$('.calTCTotal').html(txtTotal.toFixed(2));

$('#gvToolingCost_hdnTCTotal').val(txtTotal.toFixed(2));

}

inside buttonclick

string hdnAmtTotal = (gvCostWorking.FooterRow.FindControl("hdnAmtTotal") as HiddenField).Value;

this value is blank.

Thanks in advance.....

Hi all... Thanks for your time and efforts....

I sorted it out by using a hidden field outside the grid and passed the value to it. Hidden field inside the grid got changed. The one outside did not.

Thank you all..

Hi Subhashini,
You are not able to set hidden field value when you are using it inside iframe.First find iframe in page and then set hidden field value
var frame = $('#frame_id');
$('#gvToolingCost_hdnTCTotal', frame).val(txtTotal.toFixed(2));

If the above solution is helpful then,accept the answer.
