UIHint不使用EditorTemplate

Question

I have a model like this:

public class MyModel {
    [ScaffoldColumn(false)]
    public int CharityId { get; set; }

    [UIHint("Charities")]
    public SelectList Charities { get; set; }
}

Then I have an EditorTemplate called Charities.cshtml:

@model MyModel

@Html.DropDownListFor(model => model.CharityId, Model.Charities)

Then in my page:

@model MyModel

@Html.EditorForModel()

However, no matter what, it doesn't render the Charities template. I've been wracking my brain on this, and it should work.. but it's not.

Any ideas?

EDIT:

The issue is that the default Object template will not render a complex object other than itself (so called shallow dive), even if there is a UIHint. I was under the impression that a UIHint would make it render the template, but I was apparently wrong.

The fix is to not try to let the model render itself. That is sad.

Answer 1

First things first @EditoFormodel() in your page looks bizarre. I guess you meant something else.

Now to the point: you have decorated the Charities property with UIHint . This property is of type SelectList . This means that the Charities.cshtml template should be strongly typed to SelectList , not to MyModel as you did. You could simply remove this UIHint attribute and have the following view model:

public class MyModel {
    [ScaffoldColumn(false)]
    public int CharityId { get; set; }

    public SelectList Charities { get; set; }
}

and in your view:

@model MyModel
@Html.EditorForModel()

and then inside ~/Views/Shared/EditorTemplates/MyModel.cshtml have:

@model MyModel
@Html.DropDownListFor(model => model.CharityId, Model.Charities)

That's the standard conventions. If you want your editor template to be called Charities.cshtml you could do this in your page:

@model MyModel
@Html.EditorForModel("Charities")

But usually you would have the following model:

public class FooViewModel
{
    [UIHint("Charities")]
    public MyModel Charities { get; set; }
}

Now if your main view is strongly typed to FooViewModel you can:

@model FooViewModel
@Html.EditorFor(x => x.Charities)

which will render the Charities.cshtml editor template.
