Pop-up modale visualizzato in modo errato quando ModelState.IsValid = false Redirect
Sto riscontrando un problema con la visualizzazione errata del pop-up modale quando fallisce la convalida del modello su HttpPost. Quando il Modal restituisce i dati e la convalida non riesce, desidero che lo schermo torni ad avere la visualizzazione popup modale come un popup sullo schermo che ha generato inizialmente il popup. Quello che sta succedendo è che il pop-up riempie l'intero schermo, senza NESSUNA formattazione (cioè non è un popup modale a questo punto). Tuttavia, mostra i messaggi di convalida, proprio come il testo non formattato. Ecco tutti i pezzi di codice che utilizzo:
Questo è nel mio site.js
(function () {
// Initialize numeric spinner input boxes
//$(".numeric-spinner").spinedit(); // Initialize modal dialog // attach modal-container bootstrap attributes to links with .modal-link class. // when a link is clicked with these attributes, bootstrap will display the href content in a modal dialog. $('body').on('click', '.modal-link', function (e) {
e.preventDefault();
$(this).attr('data-target', '#modal-container'); $(this).attr('data-toggle', 'modal');
});
// Attach listener to .modal-close-btn's so that when the button is pressed the modal dialog disappears
$('body').on('click', '.modal-close-btn', function () { $('#modal-container').modal('hide');
});
//clear modal cache, so that new content can be loaded
$('#modal-container').on('hidden.bs.modal', function () { $(this).removeData('bs.modal');
});
$('#CancelModal').on('click', function () {
return false;
});
});
Ecco come chiamo il pop-up:
<div id="modal-container" class="modal fade" tabindex="-1" role="dialog">
<div class="modal-content"></div>
</div>
<a href="@Url.Action("CreateEdit", new { controller = "Issue", issueid = Model.IssueData.issueId, addedit = "add" })" class="modal-link btn btn-success">Add New Status</a>
Questo è il controller che gestisce l'HttpPost dal Modal PopUp
[ValidateAntiForgeryToken]
[HttpPost]
public ActionResult CreateEdit(StatusViewModel model)
{
if (ModelState.IsValid)
{
//Do Stuff
return RedirectToAction("edit");
} else
{
return PartialView("_CreateEdit", model);
}
}
Ed ecco il Modal-PopUp:

Come posso fare in modo che lo schermo torni a mostrare la pagina con il popup quando la convalida non riesce?
Risposte
Dovresti inviare il modulo tramite ajax e sostituire il modal con i dati restituiti (html della vista parziale), altrimenti restituirà direttamente la vista parziale come nuova vista.
Ho apportato alcune modifiche ai tuoi codici e puoi fare riferimento all'esempio seguente:
Modello:
public class StatusViewModel
{
public string addedit { get; set; }
public int IssueID { get; set; }
public DateTime StatusDate { get; set; }
[Required]
public string Status { get; set; }
[Required]
public string NextStep { get; set; }
[Required]
public string ColorCode { get; set; }
}
