RussianDomanda
Sto usando la griglia dell'interfaccia utente Kendo e attualmente visualizzano in modo appropriato i registri dei bambini dei genitori.Tuttavia, si scopre che in realtà avrei dovuto visualizzare i livelli N-lives contro rigorosamente genitore-figlio.Non tutti i record avranno figli, ma alcuni avranno più livelli.

Non ho problemi con la tradizionale gerarchia genitore-figlio, ma sto lottando anche con come faccio a fare il modello di dettaglio si comportano per i suoi figli.
Vorrei che il modello sia appropriato per il display per bambini / nipote - nessun indicatore a discesa se non ha bambini aggiuntivi.Suppongo di poter valutare i dati sul databornon, ma non sto solo vedendo come farlo.
Soluzione
Ci è voluto un po ', ma alla fine ho elaborato una risposta con qualche guida dai peep di Telerik. Stavo solo avendo il momento più difficile a ottenere la testa per la soluzione.
Vladimir (a Telerik) ha suggerito di utilizzare una chiamata Ajax personalizzata nella funzione dettagliata utilizzando una funzione sul successo per determinare se avevo i dati figli da considerare. Dato che avevo bisogno della griglia dei dettagli, non importa cosa, ho spostato il bambino check in un'altra funzione che crea la griglia dei dettagli. Se trovo dati figlio, aggiungo un parametro dettagliante alla nuova griglia. In caso contrario, riesco semplicemente alla griglia nuova dettagliata.
La funzione InitDetail Ajax:
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 funzione per costruire la nuova griglia dettagliata con il controllo dei bambini:
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);
};
Per completezza, ecco la pagina completa e i dati di esempio del progetto di esempio. È un sito Web .NET MVC4, utilizzando i servizi API Web per i dati e il Kendo UI per il client.

I dati vengono effettivamente hardcoded per questa app di esempio, ma lo restituisco ancora tramite API Web. Ecco un campione dei dati di livello più 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},
Ecco alcuni dati di secondo livello (dati figlio):
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},
alcuni dei dati del 3 ° livello (nipoti):
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},
E così via ...
Sta funzionando correttamente per 4 livelli nel mio test. Ci sono problemi di formattazione con le numerose griglie nidificate che affronterò.
Altri suggerimenti
Non sono sicuro se questa domanda è ancora aperta, ma una soluzione semplice è utilizzare la ricorsione nella funzione "Detailinit", come di seguito:
