Question

Jquery + Update one textbox from another textbox inside a gridview

Answer 1

A:

You still haven't provided any markup, so I have to make some assumptions. Assumption 1: "Advance Deducted" input fields have the class "adv-ded". Assumption 2: tds containing an opening advance have a class "adv-open". Assumption 3: "Closing advance" input has class "adv-close".

$('input.adv-ded').live('keypress', function(e) {
    var val;
    try {
        val = parseFloat($(this).val());
        if (val) {
            var tr = $(this).closest('tr');
            var open = parseFloat(tr.find('td.adv-open').text());
            tr.find('input.adv-close').val(open - val);
        }
    } catch (e) {

    }
});

Something like this. You might have to add some code for the formatting, but this should convey the general idea.

I was talking about HTML markup, not Microsoft-specific stuff.

Answer 2

A:

I tried using Javascript and got the answer,

function totalAmount(e, obj) {

    var tbl = document.getElementById('ctl00_ContentPlaceHolder1_gridEmployee');
    var tblRows = tbl.rows.length;
    var result = 0;
    var str1;
    if (obj != null) {
        str1 = obj.id;
    } else {
        str1 = this.id;
    }
    var Splitstr = str1.split('_');
    var lastChar = Splitstr[3].substring(3, Splitstr.length);
    if (str1 == 'ctl00_ContentPlaceHolder1_gridEmployee_ctl' + lastChar + '_TxtAdvanceDeducted') {
        var str2 = 'ctl00_ContentPlaceHolder1_gridEmployee_ctl' + lastChar + '_txtOpeningAdv';
        var str3 = 'ctl00_ContentPlaceHolder1_gridEmployee_ctl' + lastChar + '_TxtClosingAdvance';
        var txtDeduct = document.getElementById(str1).value;
        var txtOpenAdv = document.getElementById(str2).value;
        var txtCloAdv = document.getElementById(str3).value;
        var totRes = txtOpenAdv - txtDeduct;
        document.getElementById(str3).value = totRes.toFixed(2)
    }

}
