将新行添加到网格

Question

我需要Kendo Grid 让用户输入“n”个结果，然后单击一个按钮（与网格控件分开），它将获取添加到网格中的所有结果并将它们保存到数据库中。这应该是一项简单的任务，考虑到网格本身没有进行CRUD 操作，除了为数据输入添加额外的空白行...

然而，

问题是网格的内容不是静态的，并且可以根据用户输入的列大小（从 1 到 6）变化（我的示例显示了如何以数组 Lots 的形式表示它） .似乎大多数（如果不是全部）可用的教程似乎只关注静态内容，而在其他方面几乎没有帮助。

到目前为止（来自 Telerik 的一些反馈）我想出了以下...

为数组中的每个Lot 设置一个 Lot Schema 即所有数据的占位符：

var Lots = [];
    Lots.push({ ID: 13, LotNumber: "158UL" }),
    Lots.push({ ID: 14, LotNumber: "646UE" });

var LotResultsSchema = [];
    for (var p = 0; p < Lots.length; ++p) {
        LotResultsSchema.push({
            Result: {
                Count: '', 
                Mean: '',  
                SD: ''     
            }
        });
    }  

设置整体网格Schema Model ID：

var schemaModel = kendo.data.Model.define({
        id: "ID",
        fields: {
            ID: { editable: false, nullable: true },
            ResultDateTime: {
                type: "date", validation: {
                    required: true
                }
            },
            LotResults: LotResultsSchema,           
            StandardComment: {
                ID: {
                    nullable: true, validation: {
                        required: false
                    }
                },
                Description: {
                    defaultValue: "<empty>",
                    validation: {
                        required: false
                    }
                }
            },
            ReviewComment: {
                ID: {
                    nullable: true, validation: {
                        required: false
                    }
                },
                Description: {
                    defaultValue: "<empty>",
                    validation: {
                        required: false
                    }
                }
            }
        }
    });

根据上述架构为网格设置数据源：

var gridConfigDataSourceAdd = new kendo.data.DataSource({
        data: [],           
        schema: {
            model: schemaModel
        }
    });

设置列模式（再次考虑到可以根据数组大小创建多个列）：

var columnSchema = [];
columnSchemaAdd.push({ field: "ResultDateTime", format: "{0:yyyy/MM/dd hh:mm:ss}", editor: dateTimeEditor, title: 'Date Time' });
    for (var j = 0; j < Lots.length; ++j) {
        columnSchemaAdd.push({
            title: Lots[j].LotNumber,
            field: Lots[j].ID,
            columns: [{
                field: "LotResults[" + j + "].Result.Count",
                title: 'Count'
            }, {
                field: "LotResults[" + j + "].Result.Mean",
                title: 'Mean'
            }, {
                field: "LotResults[" + j + "].Result.SD",
                title: 'SD'
            }]
        });
    }
    columnSchemaAdd.push({ field: "StandardComment", title: 'Comment', editor: standardCommentDropDownEditor, template: "#=StandardComment.Description#" });
    columnSchemaAdd.push({ field: "ReviewComment", title: 'Review Comment', editor: reviewCommentDropDownEditor, template: "#=ReviewComment.Description#" });
    columnSchemaAdd.push({ command: ["edit", "destroy"] });

设置整体网格：

$("#configAddGrid").kendoGrid({
        dataSource: gridConfigDataSourceAdd,
        height: 550,
        navigatable: true,
        autoBind: false,
        editable: {
            mode: "inline"
        },
        toolbar: ["create"],
        columns: columnSchemaAdd
    });

运行此代码并单击“添加新”按钮创建新行会产生以下错误：

未捕获的类型错误：无法读取未定义的属性“结果”

我了解为什么我收到此错误，因为新项目是使用未定义的LotResults 创建的。我无法理解的是，在 Lot Schema 中设置默认值时会发生这种情况。

感谢您的任何建议，我希望有人曾经出于同样的目的使用过 Kendo Grids，因为我真的很想看看一个可行的示例！

我认为问题出在 LotResultsSchema。与其将其创建为单独的数组，不如尝试将其合并到字段类中？

<script>
var Lots = [];
    Lots.push({ ID: 13, LotNumber: "158UL" }),
    Lots.push({ ID: 14, LotNumber: "646UE" });


  var fields1 =  {
            ID: { editable: false, nullable: true },
            ResultDateTime: {

                    required: true
                }
            },          
            StandardComment: {

            field: Lots[j].ID,
            columns: [{
                field: 'Count' + Lots[j].ID ,

            },
