Pass IEnumerable list to controller

Question

In my asp.net MVC 4 project, I\'m trying to pass IEnumerable list from view to controller. The problem is that the list receiverd in the action is null. Any help please.

Answer 1

The problem is in fact that this expression:

@Html.HiddenFor(modelItem => item.ID_agent)

and similar as well cannot derive a correct name for the HTML input control, and the resulting request parameters are not parsed by model binder. Usually this is fixed by replacing foreach with for:

@fore (int i=0; i modelItem[i].ID_agent)
   @Html.RadioButtonFor(modelItem => modelItem[i].SelectedAgent, modelItem[i].ID_agent)           

   @Html.DisplayFor(modelItem => modelItem[i].nom_agent) 
   @Html.DisplayFor(modelItem => modelItem[i].prenom_agent)           
    
           

}

Note that you would need your view to be typed with IList<> or an array to allow this behavior.
