Question

使用带弹出编辑功能的kendo网格。我验证了数据是从视图中发布的（我可以在网络标签中看到它，这里看看它：

{"LetterId":12,"BodyText":"This is a test","CreatedDate":"07/31/2013","CreatedBy":"Grace Rodgers","ModifiedDate":"07/31/2013","ModifiedBy":"Grace Rodgers","PersonId":18,"FirstName":"Jason","LastName":"Bigby"}:

但是，我在控制器中的json方法上有一个断点，当鼠标悬停在model参数上时，显示所有字段都为null。以下是控制器代码的前几行：

    [HttpPost]
    public JsonResult JsonEditLetter(LetterViewModel model)
    {

和视图中的剑道代码：

var PersId = $("#PersonId").val();

    var ds_LettersGrid = new kendo.data.DataSource({
        transport: {
            read: {
                url: '@Url.Action("JsonGetLetterList", "Letter")/' + PersId,
                dataType: 'json'
            },
            update: {
                url: '@Url.Action("JsonEditLetter", "Letter")',
                dataType: 'json',
                type: "POST"
            },
            parameterMap: function (data, type) {
                if (type == "update") {

                    data.models[0].CreatedDate = kendo.toString(new Date(data.models[0].CreatedDate), "MM/dd/yyyy");
                    data.models[0].ModifiedDate = kendo.toString(new Date(data.models[0].ModifiedDate), "MM/dd/yyyy");

              return kendo.stringify(data.models[0]);
                }
            },

        },
        batch: true,
        schema: {
            model: {
                id: "LetterId",
                fields: {
                    BodyText: { editable: true },
                    CreatedDate: { editable: false, type: "date"}, 
                    ModifiedDate: { editable: false, type: "date" },
                    CreatedBy: { editable: false},
                    ModifiedBy: { editable: false },
                    PersonId: { defaultValue: PersId }
                }
            }
        },
        pageSize: 10
    });

    $(document).ready(function () {

        $("#letter-list").kendoGrid({
            dataSource: ds_LettersGrid,
            sortable: true,
            filterable: { extra: false, operators: {
                string: { startswith: "Starts with", eq: "Is equal to" }
            }
            },
            pageable: true,
            columns: [{
                field: "BodyText", title: "Letter Content", width: 400, filterable: false
            }, {
                field: "CreatedBy", title: "Author", filterable: false
            }, {
                field: "CreatedDate", title: "Original Date", format: "{0:g}", filterable: { ui: "datetimepicker" }
            }, {
                field: "ModifiedBy", title: "Edited By", filterable: false
            }, {
                field: "ModifiedDate", title: "Editted On", format: "{0:g}", filterable: { ui: "datetimepicker" }
            }, {
                command: [ "edit" ], title: "", width: "110px"
            }],
            height: "300px",
            resizable: true,
            editable: "popup"
        });
    });

您需要在id字段中添加默认值，因为客户端会生成新的id值，您在服务器自动增量中已经生成的id值及其拍摄错误

schema: {
            model: {
                id: "LetterId",
                fields: {
                    LetterId: {defaultValue: 16000}
                    BodyText: { editable: true },
                    CreatedDate: { editable: false, type: "date"}, 
                    ModifiedDate: { editable: false, type: "date" },
                    CreatedBy: { editable: false},
                    ModifiedBy: { editable: false },
                    PersonId: { defaultValue: PersId }
                }
            }
        }

我想通了，它想要一个特定的内容类型。传递的类型是一个表单，但控制器需要json。所以运输现在看起来像：

            update: {
                url: '@Url.Action("JsonEditLetter", "Letter")',
                dataType: 'json',
     >>>>>>>>   contentType: "application/json",
                type: "POST"
            },

Kendo grid - 在Controller中发布的编辑为空
