Controller: public ActionResult Aeronef(IardModel model, string id) { if (id != "") { using (var scope = RepositoryContainer.Container.BeginLifetimeScope()) { var repository = scope.Resolve(); model = repository.SingleById(id); model.IsEditing = true; return View(model); } } model.IsEditing = false; return View(model); } And the view:

@if (Model.Pilot.Count == 0)

        <label class="label-form">(Co)Propriétaire</label>
        <label class="checkbox">
            <input name="Pilot[@(Model.Pilot.IndexOf(pilots))].OwnerOrPart" type="checkbox" class="form-control" @(pilots.OwnerOrPart ? "checked='checked'" : "")>
             <i></i>

You can use @Html.CheckBoxFor(m => m.Pilot[0].OwnerOrPart, new {@class = "form-control"}) instead of <input type="checkbox" />

Edit

I have write the code corresponding to this,

@if (Model.Pilot.Count == 0)
{
    ....
    <section class="col col-md-2">
        <label class="label-form">(Co)Propriétaire</label>
        <label class="checkbox">
            @Html.CheckBoxFor(m => m.Pilot[0].OwnerOrPart, new {@class = "form-control"})
            <i></i>
        </label>
    </section>
}

You can simply write this as,

@for(int i=0; i < Model.Pilot.Count; i++){
    ....
    <section class="col col-md-2">
        <label class="label-form">(Co)Propriétaire</label>
        <label class="checkbox">
        @Html.CheckBoxFor(m => m.Pilot[i].OwnerOrPart, new {@class = "form-control"})
        <i></i>
        </label>
    </section>
}

Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index – florea_g Oct 27 '15 at 11:21
@florea_g, Sorry, I just write the code that you have provided. – Abhilash Augustine Oct 27 '15 at 11:30
@florea_g, Please take a look at the updated answer. – Abhilash Augustine Oct 27 '15 at 11:34
@florea_g, Sorry for the question. Yes I got it from your question. – Abhilash Augustine Oct 27 '15 at 11:38
@florea_g, I have tested it with a test data in my machine. It is working fine. Could you please check your data? – Abhilash Augustine Oct 27 '15 at 11:49
i don't know where is the problem i paste this : `
(Co)Propriétaire @Html.CheckBoxFor(m => m.Pilot[0].OwnerOrPart, new { @class = "form-control" })
` and i get the error You have used a list like me? – florea_g Oct 27 '15 at 12:38
@florea_g, yes, I have also used a `List`. Did you debug your problem? Please add a watch to your list `Pilot` and `Model.Pilot[0].OwnerOrPart` to see what are the values. – Abhilash Augustine Oct 27 '15 at 13:02
I am quite a beginer in c#. Add a watch is the breakpoint? If so is always false. – florea_g Oct 27 '15 at 13:19
I gived up now i use a select which is working very well. `
(Co)Propriétaire
` – florea_g Oct 27 '15 at 13:34
@florea_g, For time being you can use this `select`. But don't give up, try to solve your problem when you get time. – Abhilash Augustine Oct 28 '15 at 03:48

You should better use: <input ... @(pilots.OwnerOrPart ? "checked='true'" : "")>

The foreach is for edit the view so my problem is in if. My value in not binded is allways false. Maybe my checked is wrong but it will never work because my value isn't good – florea_g Oct 27 '15 at 11:28
