Hi,
i have a table in my view. which is bind data by jquey. I have a checkbox column in my table. which have unique Id foe each row. i have paging in my table. now my problem is when i checked some record and go to another page and checked some record here. now when i back to my previous page check box not checked.
my code is

//for getting checked id
 function GetCheckedRecord() {
        var Ids = $('input[name=chkres]:checked').map(function () {
            return $(this).val();
        }).toArray();
        if (checkval.length > 0) {          
            checkval = checkval + ',' + Ids;
        }
        else {
            checkval = Ids;
        }
       // alert(checkval);
    }

// now click on prev button
 $(".prevPageBtn").on("click", function (e) {
            e.preventDefault();
            GetCheckedRecord();
 $('input[name=chkres]').map(function () {
                var a = ($.inArray($(this).val(), checkval) != -1);               
                $(this).prop("checked", a);
            });
            fetchData(page - 1);                      
        });

//  fetchData(page - 1); is a function which bind data in to table

function fetchData(whichPage)
    {
 var request = $.ajax({          
            url: '@Url.Action("GetJsonResult", "myController")',
            method: "POST",
            data: { "page": whichPage }
        });

        request.done(function (data) {
$.each(data, function (key, val) {
                var today = new Date();
                var bgClass = (key % 2 == 0) ? "search-result-bg" : "";
                var item = '<tr class="' + bgClass + '">';
                item += '<td width="15"><input type="checkbox" id=' + val["RecordID"] + ' value=' + val["RecordID"] + ' name="chkres" class="chkres" /> </td>';
                item += '<td >' + val["RecordID"] + '</td>';
 item += '</tr>';
                items.push(item);
            });
var result = '<div id="loadingOverlay"></div><tr class="search-result-heading">';
                result += '<td width="15">Select All<br/><input class=' + 'check_all' + ' type="checkbox" /></td>';
                result += '<td >RecordId</td>';
 result += '</tr>';
                result += items.join("");
                $("#dtsResult").html(result);
            } });} 
the problem is  <pre lang="c#">$('input[name=chkres]').map(function () {var a = $(this).val();}
show last pages id's of check box.
