Estoy usando la cuadrícula de interfaz de usuario de Kendo y actualmente muestra los registros infantiles de padres adecuadamente.Sin embargo, resulta que en realidad necesitaré mostrar los niveles de N vs. estrictamente padre-hijo.No todos los registros tendrán hijos, pero algunos tendrán múltiples niveles.
Código de cuadrícula actual:
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%",

},
{

},
{
field: "JobStatusId",

editable: false,
filterable: false
}
],
sortable: {

allowUnsort: true
},

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() {

} else if (model.JobStatusId == 8) {
img.attr("src", function() {

No tengo ningún problema con la jerarquía tradicional de padres y niños, pero estoy luchando con la lucha de cómo voy a hacer que la plantilla detalla se comporte para sus hijos.
Me gustaría que la plantilla sea apropiada para la visualización de niños / nietos, sin indicador desplegable si no tiene hijos adicionales.Supongo que puedo evaluar los datos de DioBound, pero no estoy viendo cómo hacerlo.
Solución
Tomó un tiempo, pero finalmente trabajé una respuesta con alguna guía de los PEEPS en Telerik. Solo estaba teniendo el tiempo más difícil de conseguir mi cabeza alrededor de la solución.
Vladimir (en Telerik) sugirió que utilice una llamada AJAX personalizada en la función de detalleIniting usando una función en el éxito para determinar si tenía datos infantiles a considerar. Como necesitaba la rejilla detallada, sin importar qué, moví el cheque de niño en otra función que crea la cuadrícula de detalles. Si encuentro datos infantiles, agrego un parámetro de detalle para la nueva cuadrícula. Si no, simplemente rindo la nueva cuadrícula de detalles.
La función AJAX INITDETAIL:
function detailInit(e) {
var eventData = e;
$.ajax({
url: apiUrl + "ProcessJobs",
type: "POST",
data: {BoxId: e.data.JobId, AppId: e.data.AppId},
dataType: "json",
success: function(data, status, xhr) {
initializeDetailGrid(eventData, data);
}
}
La función para construir la nueva cuadrícula de detalles con el cheque para los niños:
function initializeDetailGrid(e, result) {
var moreChildren = result[0].HasChildren;
var gridBaseOptions = {
dataSource: result,
scrollable: false,
sortable: true,
columns: [
{
field: "ParentJobId",
title: "Parent Job"
},
{
field: "JobId",
title: "Job Id"
},
{
field: "JobName",
title: "Job Name",
},
{
field: "JobStatus",
title: "Status"
},
{
field: "JobStatusId",
title: "Status Code"
},
{
field: "HasChildren",
title: "Has Children"
},
{
field: "ChildrenCount",
title: "Child Jobs"
}
]
};
var gridOptions = {};
if (moreChildren) {
gridOptions = $.extend({}, gridBaseOptions, { detailInit: detailInit });
} else {
gridOptions = gridBaseOptions;
};
$("<div/>").appendTo(e.detailCell).kendoGrid(gridOptions);
};

Los datos son realmente impresos para esta aplicación de muestra, pero todavía lo devuelvo a través de la API web. Aquí hay una muestra de los datos de nivel más alto:
new Process {JobId = 108, AppId = 1, AppName = "App1", LobId = 2, LobName = "Lob2", JobName = "job_108", ParentJobName = null, ParentJobId = null, JobStatusId = 4, JobStatus = "Running", ChildrenCount = 3, HasChildren = true},
new Process {JobId = 109, AppId = 1, AppName = "App1", LobId = 2, LobName = "Lob2", JobName = "job_109", ParentJobName = null, ParentJobId = null, JobStatusId = 5, JobStatus = "Success", ChildrenCount = 4, HasChildren = true},
new Process {JobId = 110, AppId = 1, AppName = "App1", LobId = 2, LobName = "Lob2", JobName = "job_110", ParentJobName = null, ParentJobId = null, JobStatusId = 4, JobStatus = "Running", ChildrenCount = 2, HasChildren = true},
new Process {JobId = 111, AppId = 1, AppName = "App1", LobId = 2, LobName = "Lob2", JobName = "job_111", ParentJobName = null, ParentJobId = null, JobStatusId = 5, JobStatus = "Success", ChildrenCount = 5, HasChildren = true},
Aquí hay algunos datos de segundo nivel (datos infantiles):
new Process {JobId = 1037, AppId = 1, AppName = "App1", LobId = 2, LobName = "Lob2", JobName = "job_1037", ParentJobName = "job_109", ParentJobId = 109, JobStatusId = 4, JobStatus = "Running", ChildrenCount = 0, HasChildren = false},
new Process {JobId = 1038, AppId = 1, AppName = "App1", LobId = 2, LobName = "Lob2", JobName = "job_1038", ParentJobName = "job_109", ParentJobId = 109, JobStatusId = 4, JobStatus = "Running", ChildrenCount = 0, HasChildren = false},
new Process {JobId = 1039, AppId = 1, AppName = "App1", LobId = 2, LobName = "Lob2", JobName = "job_1039", ParentJobName = "job_110", ParentJobId = 110, JobStatusId = 4, JobStatus = "Running", ChildrenCount = 2, HasChildren = true},
new Process {JobId = 1040, AppId = 1, AppName = "App1", LobId = 2, LobName = "Lob2", JobName = "job_1040", ParentJobName = "job_110", ParentJobId = 110, JobStatusId = 4, JobStatus = "Running", ChildrenCount = 2, HasChildren = true},
Algunos de los datos de tercer nivel (nietos):
new Process {JobId = 5000, AppId = 1, AppName = "App1", LobId = 2, LobName = "Lob2", JobName = "job_5000", ParentJobName = "job_1039", ParentJobId = 1039, JobStatusId = 5, JobStatus = "Success", ChildrenCount = 0, HasChildren = false},
new Process {JobId = 5001, AppId = 1, AppName = "App1", LobId = 2, LobName = "Lob2", JobName = "job_5001", ParentJobName = "job_1039", ParentJobId = 1039, JobStatusId = 5, JobStatus = "Success", ChildrenCount = 0, HasChildren = false},
new Process {JobId = 5002, AppId = 1, AppName = "App1", LobId = 2, LobName = "Lob2", JobName = "job_5002", ParentJobName = "job_1040", ParentJobId = 1040, JobStatusId = 5, JobStatus = "Success", ChildrenCount = 0, HasChildren = false},
new Process {JobId = 5003, AppId = 1, AppName = "App1", LobId = 2, LobName = "Lob2", JobName = "job_5003", ParentJobName = "job_1040", ParentJobId = 1040, JobStatusId = 5, JobStatus = "Success", ChildrenCount = 0, HasChildren = false},
new Process {JobId = 5004, AppId = 1, AppName = "App1", LobId = 2, LobName = "Lob2", JobName = "job_5004", ParentJobName = "job_1041", ParentJobId = 1041, JobStatusId = 5, JobStatus = "Success", ChildrenCount = 1, HasChildren = true},
y así sucesivamente ...
Está funcionando correctamente por 4 niveles en mis pruebas. Hay problemas de formato con las múltiples cuadrículas anidadas que estaré abordando.
Otros consejos
No estoy seguro de si esta pregunta aún está abierta, pero una solución simple es usar la recursión en la función "detalle", como a continuación:
