Definire EditorTemplate per la raccolta bambino in ViewModel

Question

Ho un modello che contiene un elenco di QuestionEditModel per il quale voglio usare un EditorFor.

Normalmente, vorrei solo richiamare EditorFor sulla raccolta e l'MVC farà il resto. Tuttavia, ho bisogno del QuestionEditModel individuo di usare EditorTemplates diverse a seconda del valore di un campo all'interno dell'oggetto.

avrei pensato che il metodo per fare questo sarebbe qualcosa di simile

<%: Html.EditorFor(model=>model.Questions), [fieldname from individual question] %>

ma non riesco a capire come dirgli di esaminare la questione, che è attualmente selezionato e utilizzare il campo EntryType dalla questione per determinare quale EditorTemplate all'uso.

Così ho provato questo

            <% foreach (Reviewer.Models.QuestionEditModel qem in Model.Questions)
           {
               Html.EditorFor(q=>qem, qem.EntryType, null);
           } %>

, ma questo non rende nulla sulla pagina. La cosa strana è che se ho impostato un punto di interruzione ed eseguire il codice, questo non chiamare l'EditorTemplate corretta, i dati di modello corretto viene passato e non ci sono eccezioni, ma semplicemente non rende nulla.

C'è qualche lavoro in più ho bisogno di fare in questo scenario per ottenere la parte posteriore EditorTemplate reso in alla mia pagina?

Answer 1

Devi dire che cosa realmente rendere (<%: %>):

<% foreach (Reviewer.Models.QuestionEditModel qem in Model.Questions) { %>
     <%: Html.EditorFor(q=>qem, qem.EntryType, null) %>
<% } %>
