C# properties from model as Labelfor and EditorFor

Question

I have a ViewModel and within there are a few lists. I want to show the following properties:

    public string Status { get; set; }
    public DateTime Applicationdate { get; set; }
    public DateTime Submitdate { get; set; }
    public Boolean CustomerAgreementBoolean { get; set; }
    public DateTime CustomerAgreementBooleanDate { get; set; }
    public string MultiannualContract { get; set; }

They are part of a bigger model. It half works when I do this in the view:

        @foreach (var offeritem in Model.Offermodel)
        {
           <div class="col-md-3 mb-3">
               @Html.LabelFor(model => model.Offermodel)
               @Html.EditorFor(x => offeritem.Applicationdate, new { 
               htmlAttributes = new { @class = "form-control", required = 
               "required" } })
               @Html.ValidationMessageFor(x => offeritem.Applicationdate, "", 
               new { @class = "text-danger" })
               </div>
           }

The names of the label and editor become: Offeritem.Applicationdate instead of "Applicationdate"

Is there any way to get the correct names to show?

They are the correct names, as per the model that you have provided. The ApplicationDate is a property of OfferItem and so therefore that's the name it binds to. There may be a way around by writing your own custom model binders, but whats wrong with the name "Offeritem.Applicationdate"? — Wheels73, Jul 04 '18 at 13:50
When I pass the view back to the controller the model holds no data. I was suspecting this to be the culprit, since the names aren't the same anymore. — Carlove, Jul 04 '18 at 13:53
I see. Out of interest, are the values posted ok if you use a TextBoxFor? I would have thought that the model binding would be the same on EditorFor and TextboxFor. — Wheels73, Jul 04 '18 at 13:55
TextboxFor doesn't work either, sadly. But now that I let my test run, I see other stuff are going wrong. The three dropdownlists I've placed say: 'null reference' upon sending the data. Then the model I pass as the parameter is empty. BUT when doing a ```ModelState.IsValid``` the dropdownlist data has been sent succesfully. Other data has not. Removing the dropdownlists from the view change nothing ( except for the modelstate stating there is not data now ) — Carlove, Jul 04 '18 at 13:58
Ahh... I can see what it is. You can't use foreach for model binding.. You need a unique index. Change your loop to for int i = 0 etc... then say Model.OfferModel[i] and you should be ok. — Wheels73, Jul 04 '18 at 14:02

The names of the nested properties will be rendered like this. You can change the name attribute by passing the attribute value in HTML helper like

 @Html.EditorFor(x => offeritem.Applicationdate, new { 
               htmlAttributes = new { @class = "form-control", required = 
               "required", name="Applicationdate" } })

But then it would not bind to the nested property on form post.

You should try your code first - if you did you would see that it does nothing at all (which is fortunate because changing the `name` attribute would screw up model binding) – Jul 04 '18 at 21:56
By default strong bind will automatically generate name, id and class behind the scene. You can see through inspect it. it will generate like that. offeritem_Applicationdate – Asif Raza Jul 05 '18 at 05:32
