Kann jemand bieten bitte einen Rat zu Warum sind meine ViewModel-Werte NULL, wenn alle Felder ausgefüllt sind?
Ich habe in Google Chrome-Browser mit der Network Record-Funktion eingecheckt und alle Werte sind zurück im JSON-Format gebucht.
Vielen Dank.
------------ EDIT ---------------
Hier ist ein Teil von dem, was ich aus dem Google Chrome-Netzwerk sehen kann Monitor-
Company.Name:ABC123 Company.CreatedDate: 2014.05.13 00.00.00 ....
So ist es auf jeden Fall zurückgegeben werden.
Lustig genug, jemand hat mit der Veröffentlichung zurück "Company.Name" ein ähnliches Problem hatte. Versuchen Sie, das Feld zu entfernen, um zu sehen, ob es immer noch null zurückgibt. http://stackoverflow.com/questions/780026/asp-net-mvc-model-binding-returning-null-values –
CompanyAddressTypeId wird falsch geschrieben. Versuchen Sie auch, Ihr Formular wie folgt zu definieren - Html.BeginForm ("yourControllerNameHere", "Create", FormMethod.Post) – JB06
Dank @ErikElkins jedoch entfernt das Entfernen von Company.Name aus meiner Ansicht keinen Unterschied. Alles wird immer noch als NULL zurückgeschrieben. – RobHurd
