GridView validation using JQuery

Question

Here I've 2 columns containing checkboxes, for selecting that I'm using JQuery mention as follows

 

$("[id*=Bankcb]").live("click", function () {

var chkHeader = $(this);

var grid = $(this).closest("table");

$("input[id*=BankApprovecb]", grid).each(function () {

if (chkHeader.is(":checked")) {

$(this).attr("checked", "checked");

$("td", $(this).closest("tr")).addClass("selected");

} else {

$(this).removeAttr("checked");

$("td", $(this).closest("tr")).removeClass("selected");

}

});

});

$("[id*=BankApprovecb]").live("click", function () {

var grid = $(this).closest("table");

var chkHeader = $("[id*=Bankcb]", grid);

if (!$(this).is(":checked")) {

$("td", $(this).closest("tr")).removeClass("selected");

chkHeader.removeAttr("checked");

} else {

$("td", $(this).closest("tr")).addClass("selected");

if ($("[id*=BankApprovecb]", grid).length == $("[id*=BankApprovecb]:checked", grid).length) {

chkHeader.attr("checked", "checked");

}

}

});

$("[id*=TReDScb]").live("click", function () {

var chkHeader = $(this);

var grid = $(this).closest("table");

$("input[id*=TReDS_Statuscb]", grid).each(function () {

if (chkHeader.is(":checked")) {

$(this).attr("checked", "checked");

$("td", $(this).closest("tr")).addClass("selected");

} else {

$(this).removeAttr("checked");

$("td", $(this).closest("tr")).removeClass("selected");

}

});

});

$("[id*=TReDS_Statuscb]").live("click", function () {

var grid = $(this).closest("table");

var chkHeader = $("[id*=TReDScb]", grid);

if (!$(this).is(":checked")) {

$("td", $(this).closest("tr")).removeClass("selected");

chkHeader.removeAttr("checked");

} else {

$("td", $(this).closest("tr")).addClass("selected");

if ($("[id*=TReDS_Statuscb]", grid).length == $("[id*=TReDS_Statuscb]:checked", grid).length) {

chkHeader.attr("checked", "checked");

}

}

});
