Problem with radiobutton Asp mvc

Question

Good evening ,I am trying popular radio button varis as the value contained in my database ,however I am not able to do.

Here’s the view with the radiobutton

@model GuialetoLMS.Models.GuialetoModel
@foreach (var choice in Model.Vestibular)
{
    @Html.RadioButton("answer", @choice.idVestibular ) @choice.NomeVestibular
}

And my controller

  public ActionResult PaginaQuestao()
    {
        return View(db.Vestibular.ToList());
    }

Answer 1

Basically your view is waiting for a Viewmodel GuialetoLMS.Models.GuialetoModel and you’re passing one on to her a different kind,GuialetoLMS.Models.Vestib‌​ular.

If you wanted to pass only the Vestibular list, just change the statement in your view:

@model GuialetoLMS.Models.Vestib‌​ular
@foreach (var choice in Model)
{
    @Html.RadioButton("answer", @choice.idVestibular ) @choice.NomeVestibular
}

Even though you have only included a small snippet of your code I deduce that the first solution will not solve your problem as you should wish to pass other data that are contained in GuialetoModel, then you should create an instance of that object and popular with the content you want.

public ActionResult PaginaQuestao()
{
    var viewModel = new GuialetoLMS.Models.GuialetoModel();

    //... resto do seu código

    viewModel.Vestibular = db.Vestibular.ToList();

    return View(viewModel);
}
