【问题描述】：
我正在使用 Kendo UI Grid 并且当前适当地显示父子记录。然而，事实证明，我实际上需要显示 n 级与严格的父子级。并非每条记录都会有子记录，但有些记录会有多个级别。
当前网格代码：
var jgrid = $("#boxesgrid").kendoGrid({
columns: [
{
field: "JobId",
hidden: true
},
{
field: "PercentComplete",
hidden: true
},
{
field: "JobStatusId",
hidden: true
},
{
field: "AppName",
title: "App",
template: "<span>${AppName}</span><img class='health-img-r' id=app-${JobId} title='health' src='' alt='health_png' />",
width: "5%",
editable: false,
sortable: false
},
{
field: "JobName",
title: "Box Name",
width: "17%",
filterable: false
},
{
field: "StartTime",
title: "Start Time",
width: "14%",
filterable: false
},
{
field: "EndTime",
title: "End Time",
width: "14%",
filterable: false
},
{
field: "JobStatusId",
title: "Status",
template: "<img class='health-img-l' id=app-${JobId} title='health' src='' alt='health_png' /><span>${JobStatus}</span>",
editable: false,
filterable: false
}
],
sortable: {
mode: "single",
allowUnsort: true
},
pageable: {
pageSizes: [50],
numeric: true,
refresh: true,
pageSize: 50
},
autoBind: false,
scrollable: false,
resizable: true,
detailInit: detailInit,
dataSource: boxesDataSource,
dataBound: function () {
var grid = this;
grid.tbody.find(">tr").each(function () {
var row = $(this).closest("tr");
var model = grid.dataItem(row);
var img = $(this).find("img");
if (model.JobStatusId == 4 && model.PercentComplete < 100) {
img.attr("src", function() {
return imgSrc + imgGreen;
});
} else if (model.JobStatusId == 4) {
img.attr("src", function() {
return imgSrc + imgAmber;
});
} else if (model.JobStatusId == 7) {
img.attr("src", function() {
return imgSrc + imgIce;
});
} else if (model.JobStatusId == 8) {
img.attr("src", function() {
return imgSrc + imgHold;
});
} else if (model.JobStatusId == 5) {
img.attr("src", function() {
return imgSrc + imgBlue;
});
} else {
img.attr("src", function() {
return imgSrc + imgRed;
});
}
});
}
}).data("kendoGrid");
当前子网格：
function detailInit(e) {
$("<div/>").appendTo(e.detailCell).kendoGrid({
dataSource: {
transport: {
read: {
url: "/api/BoxJobs"
},
parameterMap: function (data) {
data.parentid = e.data.JobId;
data.appid = e.data.AppId;
return kendo.stringify(data);
}
},
schema: {
model: { id: "JobId" }
},
serverPaging: true,
serverFiltering: true,
serverSorting: true
},
scrollable: false,
sortable: true,
columns: [
{
field: "JobId",
hidden: true
},
{
field: "PercentComplete",
hidden: true
},
{
field: "JobStatusId",
hidden: true
},
{
field: "JobName",
title: "Job Name",
template: "<span>${JobName}</span><img class='health-img-l' id=app-${JobId} title='health' src='' alt='health_png' />",
width: "23%",
filterable: false,
sortable: false
},
{
field: "StartTime",
title: "Start Time",
width: "10%",
editable: false,
filterable: false,
sortable: false
},
{
field: "EndTime",
title: "End Time",
width: "10%",
editable: false,
filterable: false,
sortable: false
},
{
field: "ElapsedTime",
title: "Elapsed</br>Time",
width: "4%",
editable: false,
filterable: false,
sortable: false
},
{
field: "MeanRunTime",
title: "Mean Run</br>Time",
width: "3.5%",
editable: false,
filterable: false,
sortable: false
},
{
field: "PredecessorJobName",
title: "Previous Job",
width: "17%",
filterable: false,
sortable: false
},
{
field: "JobStatusId",
title: "Status",
template: "<img class='health-img-l' id=app-${JobId} title='health' src='' alt='health_png' /><span>${JobStatus}</span>",
editable: false,
filterable: false,
sortable: false
}
],
dataBound: function () {
var grid = this;
grid.tbody.find(">tr").each(function () {
var row = $(this).closest("tr");
var model = grid.dataItem(row);
var img = $(this).find("img");
if (model.JobStatusId == 4 && model.PercentComplete < 100) {
img.attr("src", function() {
return imgSrc + imgGreen;
});
} else if (model.JobStatusId == 4) {
img.attr("src", function() {
return imgSrc + imgAmber;
});
} else if (model.JobStatusId == 7) {
img.attr("src", function() {
return imgSrc + imgIce;
});
} else if (model.JobStatusId == 8) {
img.attr("src", function() {
return imgSrc + imgHold;
});
} else if (model.JobStatusId == 5) {
img.attr("src", function() {
return imgSrc + imgBlue;
});
} else {
img.attr("src", function() {
return imgSrc + imgRed;
});
}
});
}
});
}
顶级数据示例：

]
我对传统的父子层次结构没有任何问题，但我什至在如何使详细模板为其子级行为时都在苦苦挣扎。
我希望模板适合子/孙显示 - 如果它没有其他子级，则没有下拉指示符。我假设我可以评估数据绑定上的数据，但我只是不知道该怎么做。
