<script>
        $("#ddlTrainingType").change(function (e) {
            $.ajax({
                url: "TrainingReport.aspx/BindTrainingModule",
                data: '{"Id": + $(this).val() }',
                debugger;

                    $("#lstTrainingModule").html(result.d);
                },
                error: function (xhr, status, error) {
                    alert("error0");
                    alert("Result: " + status + " " + error + " " + xhr.status + " " + xhr.statusText)
                }
