<div>
    <table>
        <tr>
            <td>
                <div>
                    <label for="ID">ID</label>
                </div>
                <div data-container-for="data.ID">
                    <input id="id" data-bind="value: data.ID" style="width: 250px;" name="ID" type="text" />
                </div>
            </td>
        </tr>
        <tr>
            <td>
                <div>
                    <label for="NID" id="lcid">NID</label>
                </div>
                <div>
                    <input id="cid" />
                </div>
            </td>
            <td>
            </td>
        </tr>
    </table>
</div>

Service:

$(document).ready(function () {
    $("#cid").kendoDropDownList({
        dataTextField: "NID",
        dataValueField: "NID",
        dataSource: {
            transport: {
                read: {
                    dataType: "jsonp",
                    url: "/Services/getNID",
                }
            }
        }
    });
});
