ASP.NET MVC Yes/No Radio Buttons with Strongly Bound Model MVC

Does anyone know how to bind a Yes/No radio button to a boolean property of a Strongly Typed Model in ASP.NET MVC.

Model

public class MyClass
{
     public bool Blah { get; set; }
}

View

<%@  Page Title="blah"  Inherits="MyClass"%>
    <dd>
        <%= Html.RadioButton("blah", Model.blah) %> Yes
        <%= Html.RadioButton("blah", Model.blah) %> No
    </dd>

Thanks

SOLUTION:

Thanks for Brian for the direction but it was the opposite of what he wrote. As so -

<%@  Page Title="blah"  Inherits="MyClass"%>
<dd>
    <%= Html.RadioButton("blah", !Model.blah) %> Yes
    <%= Html.RadioButton("blah", Model.blah) %> No
</dd>

If I can throw my hat into the ring, I think there is a cleaner way than the existing answers to reuse the radio button functionality.

Let's say you have the following property in your ViewModel:

<!-- language: lang-vb -->

Public Class ViewModel
    <Display(Name:="Do you like Cats?")>
    Public Property LikesCats As Boolean
End Class

You can expose that property through a reusable editor template:

First, create the file Views/Shared/EditorTemplates/YesNoRadio.vbhtml

Then add the following code to YesNoRadio.vbhtml:

<!-- language: lang-html -->

@ModelType Boolean?

<fieldset>
    <legend>
        @Html.LabelFor(Function(model) model)
    </legend>

    <label>
        @Html.RadioButtonFor(Function(model) model, True) Yes
    </label>
    <label>
        @Html.RadioButtonFor(Function(model) model, False) No
    </label>
</fieldset>

You can call the editor for the property by manually specifying the template name in your View:

<!-- language: lang-html -->

@Html.EditorFor(Function(model) model.LikesCats, "YesNoRadio")

Pros:

• Get to write HTML in an HTML editor instead of appending strings in code behind.
• Preserves the DisplayName DataAnnotation
• Allows clicks on Label to toggle radio button
• Least possible code to maintain in form (1 line). If something is wrong with the way it is rending, take it up with the template.
