Form not passing values on POST - asp.net-mvc

Question

Here's my view code:
#model pedidosOnlineMVC.Models.ViewModel.AdmView
#using pedidosOnlineMVC.Models
#{
Layout = "~/Views/Administrador/_LayoutAdm.cshtml";
List<Usuario> lu = pedidosOnlineMVC.Controllers.UsuarioController.favoreds(Model.adm.estabelecimento.Estabelecimento_Id);
}
#using (var f = Html.Bootstrap().Begin(new Form()))
{
using (var p = Html.Bootstrap().Begin(new Panel()))
{
using (var t = Html.Bootstrap().Begin(new Table()))
{
using (var h = t.BeginHeader())
{
using(var hr = h.BeginHeaderRow())
{
#hr.Cell("Usuário")
#hr.Cell("Status")
}
}
using(var b = t.BeginBody())
{
for(int i=0;i<lu.Count;i++)
{
using(var c = b.BeginRow())
{
#f.FormGroup().CustomControls(Html.HiddenFor(model => model.Usuario_Id[i], lu[i].Usuario_Id))
#c.Cell(lu[i].nome)
#c.Cell(f.FormGroup().CustomControls(Html.Bootstrap().CheckBoxFor(model=>model.checkAuts[i])))
}
}
}
}
using (var pf = p.BeginFooter())
{
#f.FormGroup().CustomControls(#Html.HiddenFor(model => model.adm.Administrador_Id, Model.adm.Administrador_Id))
#f.FormGroup().CustomControls(Html.Bootstrap().SubmitButton().Text("Autorizar"))
}
}
}
And I had a similar problem here: cshtml page not passing date value on post, but what I did then doesn't work here.
I tried looking in the network window in the developer tools and I can see the ID values (Administrador_ID and Usuario_ID) being sent on post, but they never reach my controller.
Here's the code for the controller:
[HttpPost]
public ActionResult autCli(AdmView adm)
{
return null;
}
It has no code in it because I still didn't get it to work, but the parameters should still work when debugging, but I get NULL in every attribute instead.
If anyone can help, I'd appreciate it.
AdmView model, as requested:
public class AdmView
{
public Administrador adm { get; set; }
public Produto prod { get; set; }
public virtual List<bool> checkAuts { get; set; }
public virtual List<int> Usuario_Id { get; set; }
}

Answer 1

Try to use the FormCollection to pass data from view to controller.
Just like this:
[HttpPost]
public ActionResult autCli(FormCollection collection)
{
strint Usuario_Id = collection["Usuario_Id"]; //You can get data with this way...
return View();
}

Answer 2

Add [HttpPost] before your ActionResult method.
