ASP MVC 5.2 using nested dictionaries for htmlAttributes in EditorFor

I want to pass a nested Dictionary into the EditorFor viewData.

@{
    var viewData = new RouteValueDictionary();
    var htmlAttributes = new RouteValueDictionary();
    htmlAttributes.Add("title", "foo");
    viewData["htmlAttributes"] = htmlAttributes;
}
Html.EditorFor(model => model.SomeProperty, viewData);

The problem is that the tile="foo" does not get rendered. When I'm using

var htmlAttributes = new {title = "foo"};

everything is working as expected.

I need htmlAttributes to be a Dictionary, because in my application it is dynamically generated.

So how can I pass a Dictionary in there. I already tried to pass in thmlAttributes as an ExpandoObject, but that does not work either.

Solution

  • It is currently not possible (MVC 5.2) see this Bug: https://aspnetwebstack.codeplex.com/workitem/1736
