ASP.NET MVC - using model property as form, how can I post to action?

Consider the following model:

public class BandProfileModel
{
    public BandModel Band { get; set; }
    public IEnumerable<Relationship> Requests { get; set; }
}

and the following form:

<% using (Html.BeginForm()) { %>
    <%: Html.EditorFor(m => m.Band) %>
    <input type="submit" value="Save Band" />
<% } %>

which posts to the following action:

public ActionResult EditPost(BandProfileModel m, string band)
{
    // 开发者_如何学编程stuff is done here, but m is null?

    return View(m);
}

Basically, I only have one property on my model that is used in the form. The other property in BandProfleModel is just used in the UI for other data. I'm trying to update just the Band property, but for each post, the argument "m" is always null (specifically, the .Band property is null).

It's posting just fine to the action, so it isn't a problem with my route. Just the data is null.

The ID and name attributes of the fields are BAND_whatever and Band.whatever (whatever being a property of Band), so it seems like it would work...

What am I doing wrong? How can I use just one property as part of a form, post back, and have values populated via the model binder for my BandProfileModel property in the action? Thanks.

You're creating Editors for Band which is of type BandModel, but are expecting a BandProfileModel in your action. Either accept a BandModel in your EditPost action. Or create editors for the BandProfileModel.

Nevermind. It was due to that "band" string argument. It was confusing it. I changed that and it works.
