TextBoxFor错误地设置属性名称，从而不绑定模型

Question

In one of my strongly typed Views, of type ProfileModel , I invoke an editor for another type:

@model MVC3App.WebUI.Models.ProfileModel

<div class="contact-form">
    @Html.EditorFor(x => x.ContactModel)
</div>

I have this simple model:

public class ContactModel
{
    [Required]
    [Display(Name = "Name:")]
    public string Name { get; set; }

    [Required]
    [Display(Name = "Email:")]
    public string Email { get; set; }

    [Required]
    [Display(Name = "Message:")]
    public string Message { get; set; }
}

And this is what I use in my EditorTemplate view for ContactModel to display the textbox:

@model MVC3App.WebUI.Models.ContactModel

@Html.TextBoxFor(model => model.Name, new { placeholder = "* Name" })

The generated HTML:

<input data-val="true" 
       data-val-required="The field Name: is required." 
       id="ContactModel_Name" 
       name="ContactModel.Name" 
       placeholder="* Name" type="text" value="">

When POSTed back to the server the value is not binding to the model properties.

[HttpPost]
public ActionResult SendPatientContact(ContactModel model)
{
    if (ModelState.IsValid)
    {
        // model.Name is null. :S

        return RedirectToAction("ThankYou");
    }

    return RedirectToAction("ThankYou");
}

If I manually set the name of the textbox to name="Name" , the value is binding correctly to the model property. Any suggestions?

在您的情况下，您不应使用@Html.EditorFor方法，而应使用@{Html.RenderPartial("_ContactPartialView", Model.ContactModel);}
