Checking a checkbox if == data from controller

I know there is already an answer for how to check a checkbox with jQuery (Checking a checkbox with jQuery?) however I am struggling more with iterating through a table and comparing two values.

I have a devexpress GridView and TreeList, the GridView contains a list of Usernames, the TreeList contains a list of right names and id's.

What i would like to happen is:

1. User Clicks on a Username in table.
2. Username is sent to controller and a list of right id's is returned.
3. Returned id's are compared to TreeList's right id's
4. If (returned right id == treelist right id) Tick the Tree List node checkbox.

I am having trouble with part 3 & 4, I guess JQuery is the best way to go about it but i'm not sure how to do it. I do not want to use Devexpress Client-Side Please see my code below:

JQuery

$(".dxgv").click(function () {
    var $row = $(this).closest("tr");    
    var $tds = $row.find("td:nth-child(1)");
    $.each($tds, function () {
        var insertText = $(this).text();
        $.ajax({
            url: '@Url.Action("GetUserRights", "Home")',
            data: { 'userLogin': insertText },
            type: "post",
            cache: false,
            success: function (userrightslist) { @*SOMETHING HERE?*@ }
        });
    });
});

Home Controller

public ActionResult GetUserRights(string userLogin)
{
    if (userLogin != null)
    {
        Manager manager = new Manager();
        var data = manager.GetAllRightsRows();
        var userlogin = manager.GetUserData(userLogin);
        var userrights = userlogin.RightsId.Select(s => new { id = s, text = s });
        var rightdetails = manager.GetAllRightsRows();
        List<int> userrightslist = new List<int>();
        foreach (var u in userrights)
        {

            foreach (var i in rightdetails)
            {
                if (u.id == i.Id)
                {
                    var RightID = i.Id;
                    userrightslist.Add(RightID);

                } 
            }
        }


        return View("Index", userrightslist);
    }

    return View("Index");
}

Checkbox Unchecked Example

<span class="dxWeb_edtCheckBoxUnchecked dxICheckBox dxichSys" id="RightsTreeList_R-2_D"><span class="dxKBSW"><input value="U" type="text" readonly="readonly" /></span></span>

Checkbox Checked Example

<span class="dxICheckBox dxichSys dxWeb_edtCheckBoxChecked" id="RightsTreeList_R-2_D"><span class="dxKBSW"><input value="U" type="text" readonly="readonly" /></span></span>

Please don't recommend any changes to the checkbox code as this is created by Devexpress so I cannot make changes.

Home Controller Results Example

userrightslist  Count = 117 System.Collections.Generic.List<int>

        [0] 1   int

        [1] 2   int

        [2] 3   int

        [3] 5   int

        [4] 6   int

        [5] 686 int

        [6] 7   int

Thanks and please let me know if you need any more information etc.
