Send a list of objects to controller without JSON

Question

I'm doing a form that contains a List<object>. This List<object> must be sent to the controller but I don't want to use JSON. Is it possible? Do I have to test with id="MyField[i]" or anything like that?

Here is the Razor code that is targeted:

@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">
        <h4>Ajout de Critères sur l'audit @Model.idAudit</h4>
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })


        @foreach (var item in Model.criteresList)
        {

            <div class="form-group">
                @Html.LabelFor(model => item.nomCritere, htmlAttributes: new { @class = "control-label col-md-2" })
                <div class="col-md-10">
                    @Html.EditorFor(model => item.nomCritere, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(model => item.nomCritere, "", new { @class = "text-danger" })
                </div>
            </div>

            <div class="form-group">
                @Html.LabelFor(model => item.libelle, htmlAttributes: new { @class = "control-label col-md-2" })
                <div class="col-md-10">
                    @Html.EditorFor(model => item.libelle, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(model => item.libelle, "", new { @class = "text-danger" })
                </div>
            </div>
        }

        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Create" class="btn btn-default" />
            </div>
        </div>
    </div>
}

And the Controller

        [HttpPost]
        public ActionResult Criteres(CritereViewModel model)
        {
            // Call BL to save them all

            return RedirectToAction("Index");
        }

Is the code you posted working? Not sure if you want an alternative or want this code to work? — adiga

Well this article explains everyting about binding arrays in MVC

If you want to post your form values with bare hands you need to do something like this:

    @for (var i = 0 ;i < in Model.criteresList.Count();i++)
    {  
@Html.EditorFor(model => Model.criteresList[i].nomCritere, new { htmlAttributes = new { @class = "form-control" } })  
    }

the previous answer is viable and what you say also works (id = "MyField [i]") you just have to add the object properties.

@Html.Hidden(string.Format("model.criteresList[{0}].nomCritere", index),someValue)

<select name="model.criteresList[@index].nomCritere" value="someValue">

in controller

[HttpPost]
public ActionResult Criteres(CritereViewModel model)
{}
