MVC 5 Model Child list can't render in Partial view

Question

I am new to ASP.NET MVC 5 . On debug mode, I saw some values being looped to the partial view but in UI no values are being displayed.

My Model

public class Model
{
    public int ID { get; set; }

    public string UserID { get; set; }

    public List<ReferenceModel> ReferenceModelList{ get; set; }
}

My Controller

public ActionResult GetModel(string dataobject, int id = 0)
{
    Model model = new Model();
    model = BL.GetModel(dataobject, id);
    return PartialView("_ReferenceModelList", model);
}

ReferenceModelList(PartialView)

@model Web.Model.Model
@{
    Layout = null;
}

@foreach (var menurefitem in Model.ReferenceModelList)
{
    <tr>
        <td>
            @Html.DisplayFor(modelItem => menurefitem.Code)
        </td>
        <td>
            @Html.DisplayFor(modelItem => menurefitem.Description)
        </td>
    </tr>
}

Answer 1

您需要像这样从主UI调用Controller方法

@{Html.RenderAction("GetModel","SAPSecurity");}

Answer 2

At first you should instantiate your list at the constructor of your class.I think your problem should be solved.

public class Model
{
    public Model()
    {
        ReferenceModelList=new List<ReferenceModel>();
    }
    public int ID { get; set; }

    public string UserID { get; set; }

    public List<ReferenceModel> ReferenceModelList { get; set; }
}
