@Html.CheckBoxListFor(model => model.sbuIDs, 
                      model => model.Availablesbu,
                      sb => sb.sbuID,

[HttpGet]
public ActionResult AddUsers()
{
    var Uvm = new UsersViewModel();

    var Selectedsbu = new List<sbu>();
    Uvm.Availablesbu = _User.Getallsbu();
    Uvm.Selectedsbu = Selectedsbu;
    return View(Uvm);
}

public class sbu
{
    public int UserID { get; set; }
    public int sbuID { get; set; }
    public string sbuName { get; set; }
}

public class UsersViewModel()
{
    public IEnumerable<sbu> sbu = null;
    sbu = new List<sbu>();
    public IEnumerable<sbu> Availablesbu { get; set; }
    public IEnumerable<sbu> Selectedsbu { get; set; }
    public string[] sbuIDs { get; set; }
}

Update

Below is the ajax request i will use:

<script>
    $("#CheckBoxListFor").change(function () {
        debugger;
        var favorite = [];
        $.each($("input[name='sbuIDs']:checked"), function () {
            favorite.push($(this).val());
        });

        $.ajax({
            type: "POST",
            dataType: "json",
            contentType: "application/json",
            url: '@Url.Action("Getvalues", "Home")',

            data: JSON.stringify({ values: favorite })
        });

    });
</script>

Controller code

public JsonResult Getvalues(string[] values)
{
    //
}

Rendered in HTML a check box list will have a shared name but will have different ids being the name followed by a - and a number identifying the index.

You can use jQuery to get a list of those selected.

$('[name="checkBoxListName"]:checked');

To get an array of their values:

var values = $('[name="checkBoxListName"]:checked').get();

Your sample script should work with some minor changes. 1) use the name selector as your checkboxes will have different ids. 2) Wrap the code in $(document).ready . 3) Just post the raw object and not a string:

<script>
$(document).ready(function() {
    $("[name='checkBoxListName']).change(function () {
        // code here.
        data: { values: favorite }
    });
 });
</script>
