How to pass data from a controller to a view that is not yours?

  • 772

For example, I have the EliminaUsuarios controller whose view is EliminarUsuarios.cshtml and another where the controller is Users and the view is Users.cshtml. What I want is to pass the value of ViewBag.Error in EliminateUsuarios (controller) to Users (View) so that I can show the error

namespace Sistema.Controllers
{
    public class Usuarios : Controller
    {
        public ActionResult Usuarios()
        {
            return(db.Usuarios.Tolist())
        }

        public ActionResult EliminarUsuario
        {
            // ?????????????????aquí regresar a la vista                 
            // Usuarios con el valor de  ViewBag.Error
        }
    }
}


/////////////Vista Usuarios
@model IEnumerable<Sistema.Models.Usuario>
@{ 
    ViewBag.Title = "Usuarios";
}
///Recibir valor de ViewBabag
@ViewBag.Error

    Your class should be called UsuariosControllerinstead ofUsuarios

    namespace Sistema.Controllers
{
    public class Usuarios : Controller
    {
      public ActionResult Usuarios()
        {
         ViewBag.Error = TempData["Error"];
         return(db.Usuarios.Tolist());
        }
      public ActionResult EliminarUsuario()
        {           
        TempData.Add("Error", "El detalle del error");
        return RedirectToAction("Usuarios"); 
        }
    }
}

/////////////Vista Usuarios
@model IEnumerable<Sistema.Models.Usuario>
@{ 
    ViewBag.Title = "Usuarios";
}
///Recibir valor de ViewBabag
@ViewBag.Error

    Since you are just starting out with ASP.net MVC, I recommend you visit the following workshop that I did the previous month: https://www.youtube.com/watch?v=6LZG76aLykY

  2. You have two options:

    1) Return a RedirectToAction, which will execute the code Actionyou called:

    public ActionResult EliminarUsuario()
{
    return RedirectToAction("Usuarios");
}

    2) Directly return a Viewdifferent one to the one that corresponds to the Action, passing its name (Returns the View without going through the Action Usuarios):

    public ActionResult EliminarUsuario()
{
    return View("Usuarios");
}
