ASP.NET MVC : access container from EditorTemplate

Question

I have a view model AssetFreezeViewModel.cs that contains the following property :

public AssetFreezeAccountBalanceViewModel AccountBalanceInfo { get; set; }

I have a view Details.cshtml based on the ViewModel above with that line :

@Html.EditorFor(x => x.AccountBalanceInfo)

In \Views\Shared\EditorTemplates\ , I have a template AssetFreezeAccountBalanceViewModel.cshtml whose name is the same as the type of AccountBalanceInfo that is AssetFreezeAccountBalanceViewModel (by convention)

In that EditorTemplate, I have :

@Html.EditorFor(model => model.DeviseId)

In AssetFreezeAccountBalanceViewModel.cs, I have :

[UIHint("DropDownList")]
public Int16? DeviseId { get; set; }

public IEnumerable<SelectListItem> DeviseIdList { get; set; }

Finally, in \Views\Shared\EditorTemplates\ I have DropDownList.cshtml (applied to DeviseId by convention) :

@model dynamic
@{
    var propertyNameLookup = this.ViewData.ModelMetadata.PropertyName + "List";
    var property = this.ViewData.ModelMetadata.Container.GetType().GetProperty(propertyNameLookup);
...
}

When the code hits @Html.EditorFor(model => model.DeviseId) , we enter DropDownList.cshtml where Container is null then crash.

How can I access Container (= parent) from that EditorTemplate which is 2 level down from its view ?

Answer 1

I just added @model AssetFreezeAccountBalanceViewModel At the top of AssetFreezeAccountBalanceViewModel.cshtml

Here is a sample project.

Hope that helps.
