applying _Layout view to in mvc

Mark Tabor

Hi I have a _layout View which is basically having a model call as shown below

@model Pakeeza_Estate.Models.Country

Now i have created a new Index view and i want to use this above layout as my layout , my index view itself is having an model class as

@model Pakeeza_Estate.Models.Property

now when i set the layout property to

Layout = "~/Views/Shared/_Layout.cshtml";

}

and i run the project it gives error

There is no ViewData item of type 'IEnumerable' that has the key 'CountryId'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in

i knew it is asking to give the model of country as well , but i already have another model with this view so how i can add two models to the same view , other then Viewmodel apporoach can i pass the model in controller method instead of binding it using view

Hi Mark,

Please refer below link, I think you have to assign values from viewmodel to your entity class then save it. First iterate your view model and assign each properties to entity from view model and that apply savechange().

Jignesh Kumar thanks for your reply i have created a view model as showne below
public class ViewModel
{
public IEnumerable sliders { get; set; }
public Property properties { get; set; }
public IEnumerable countries { get; set; }
public Country countriess { get; set; }

}
after that now my Index model is using this viewModel as model object so it is not giving any error it works fine .
but in my home controller i have a Create[Post} method as shown below
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "Id,Property_name,Property_Description,Property_Type,Property_Country,Property_City,Property_State,Property_Area,Property_Bed,Property_Bath,Property_price,Property_image,Property_for,IsActive,Date_Created,Date_Modified,property_address")] Property property)
{
if (ModelState.IsValid)
{
db.Properties.Add(property);
db.SaveChanges();
return RedirectToAction("Index");
}
ViewBag.Property_City = new SelectList(db.Cities, "CityId", "CityName", property.Property_City);
ViewBag.Property_Country = new SelectList(db.Countries, "CountryId", "CountryName", property.Property_Country);
ViewBag.Property_for = new SelectList(db.Property_For, "int", "Name", property.Property_for);
ViewBag.Property_Type = new SelectList(db.Property_types, "Id", "Name", property.Property_Type);
ViewBag.Property_State = new SelectList(db.States, "StateId", "StateName", property.Property_State);
return View(property);
}
you can see it is taking Property model as object but when i post the data then it is getting value of viewmodel property {public Country countriess { get; set; } but it is not getting values of property class . when i change the model from my index view from Viewmodel to Property then it get all values .

Hi Mark,

I think you can use viewmodel or dynamic model which can meet your requrement. Please find below link,

Hi,
