If I understand you correct, you need select rows with selected checkbox and pass data of this rows to ajax. Yes, this possible, but please provide your code first. This is the way how to iterate over tr with checkbox cheked.

<script type="text/javascript">
        $(document).ready(function () {
            $('#MainContent_gvOrders  tr:has(:checkbox:checked)').filter(function () {
                //Insert your ajax call here. You must use jQuery foreach to be able work with each of rows that match criteria.
                });
        });
    </script>

Something like that to iterate over filtered tr:

     $("div.test-block").each(function () {
            var id = $(this).find('input[type=hidden]').val();
            var style = $(this).find("h3").text();
            var option = $(this).find("a").text();
            var selected;
            if (option == "Добавить") {
                selected = false;
            }
            else if (option == "Добавлено") {
                selected = true;
            }
            //Данные
            var json = "{'Id': " + id + ", 'UserGUID':'" + $("#MainContent_guid").val() + "', 'Style':'" + style + "', 'Selected':'" + selected + "'}"
            $.ajax({
                type: "PUT",
                dataType: "json",
                contentType: 'application/json; charset=utf-8',
                url: "/api/usersprofiles/" + id,
                data: json,
                success: function () {
                    setTimeout(function () {
                        window.location.replace("default.aspx");
                    }, 3000);
                },
                error: function (xhr, status, error) {
                    var err = eval("(" + xhr.responseText + ")");
                    alert(err.Message);
                }
            });
        });

In ajax call you must change method accordingly to PUT, POST or DELETE.
