json - jqGrid 表单编辑 - 如何将编辑行发布到 sql 服务器

Question

我在我的 sharepoint webpart 中使用 jqGrid 并尝试使用表单编辑网格。我不知道如何将数据发布回 sql server 数据库以进行添加/更新/删除。我正在使用将接受来自网格的 JSON 数据的 WCF 服务。

WCF 方法：

[OperationContract]
[WebInvoke(BodyStyle = WebMessageBodyStyle.Wrapped,
    Method = "POST",
    RequestFormat = WebMessageFormat.Json,
    ResponseFormat = WebMessageFormat.Json)]
bool UpdateProjectDeliverable(string ProjectName, string CriticalItemInfo);

JQGrid - 表单编辑：

$('#PrjDeliverablesGrid').jqGrid({
            datatype: 'json',
            colNames: ['ActivityDescription', 'Type', 'CompletionDate'],
            colModel: [
                            { name: 'ActivityDescription', index: 'ActivityDescription', width: 200, sortable: false, editable: true, edittype: "textarea", editoptions: { rows: "2", cols: "10" }, formoptions: { rowpos: 1, elmprefix: "(*)" }, editrules: { required: true} },
                        { name: 'Type', index: 'Type', width: 90, editable: true, edittype: 'select', editoptions: {
                            value: function () {
                                var EditVal = LoadDeliverableTypes();
                                return EditVal;
                            }
