MVC Razor Radio Button

In partial view I work with textboxes like this.

@model Dictionary<string, string>
@Html.TextBox("XYZ", @Model["XYZ"])

How can i generate radiobuttons, and get the desired value in the form collection as YES/NO True/False) ? Currently i am getting null for "ABC" if i select any value for the below.

   <label>@Html.RadioButton("ABC", @Model["ABC"])Yes</label>
   <label>@Html.RadioButton("ABC", @Model["ABC"])No</label>

Controller

        public int Create(int Id, Dictionary<string, string> formValues)
        {
         //Something Something
        }

In order to do this for multiple items do something like:

foreach (var item in Model)
{
    @Html.RadioButtonFor(m => m.item, "Yes") @:Yes
    @Html.RadioButtonFor(m => m.item, "No") @:No
}

Simply :

   <label>@Html.RadioButton("ABC", True)Yes</label>
   <label>@Html.RadioButton("ABC", False)No</label>

But you should always use strongly typed model as suggested by cacho.

I solve the same problem with this SO answer.

Basically it binds the radio button to a boolean property of a Strongly Typed Model.

@Html.RadioButton("blah", !Model.blah) Yes 
@Html.RadioButton("blah", Model.blah) No 

Hope it helps!

I done this in a way like:

  @Html.RadioButtonFor(model => model.Gender, "M", false)@Html.Label("Male")
  @Html.RadioButtonFor(model => model.Gender, "F", false)@Html.Label("Female")

MVC5 Razor Views

Below example will also associate labels with radio buttons (radio button will be selected upon clicking on the relevant label)

// replace "Yes", "No" --> with, true, false if needed
@Html.RadioButtonFor(m => m.Compatible, "Yes", new { id = "compatible" })
@Html.Label("compatible", "Compatible")

@Html.RadioButtonFor(m => m.Compatible, "No", new { id = "notcompatible" })
@Html.Label("notcompatible", "Not Compatible")

<label>@Html.RadioButton("ABC", "YES")Yes</label>
<label>@Html.RadioButton("ABC", "NO")No</label>

MVC Razor provides one elegant Html Helper called RadioButton with two parameters (this is general, But we can overload it uptil five parameters) i.e. one with the group name and other being the value

<div class="col-md-10">
    Male:   @Html.RadioButton("Gender", "Male")
    Female: @Html.RadioButton("Gender", "Female")
</div>                         

<p>@Html.RadioButtonFor(x => x.type, "Item1")Item1</p>
<p>@Html.RadioButtonFor(x => x.type, "Item2")Item2</p>
<p>@Html.RadioButtonFor(x => x.type, "Item3")Item3</p>

This works for me.

@{ var dic = new Dictionary<string, string>() { { "checked", "" } }; }
@Html.RadioButtonFor(_ => _.BoolProperty, true, (@Model.BoolProperty)? dic: null) Yes
@Html.RadioButtonFor(_ => _.BoolProperty, false, (!@Model.HomeAddress.PreferredMail)? dic: null) No

I wanted to share one way to do the radio button (and entire HTML form) without using the @Html.RadioButtonFor helper, although I think @Html.RadioButtonFor is probably the better and newer way (for one thing, it's strongly typed, so is closely linked to theModelProperty). Nevertheless, here's an old-fashioned, different way you can do it:

    <form asp-action="myActionMethod" method="post">
        <h3>Do you like pizza?</h3>
        <div class="checkbox">
            <label>
                <input asp-for="likesPizza"/> Yes
            </label>
        </div>
    </form>

This code can go in a myView.cshtml file, and also uses classes to get the radio-button (checkbox) formatting.
