    <div class="form-horizontal">

        <h4>TestModelh4>

        <hr />

        @Html.ValidationSummary(true, "", new { @class = "text-danger" })

        <div class="form-group">

            @Html.LabelFor(model => model.IsQuotedTariff, htmlAttributes: new { @class = "control-label col-md-2" })

            <div class="col-md-10">

                <div class="checkbox">

                    @Html.RadioButtonFor(model => model.IsQuotedTariff,"Yes") <text>Yestext>

                    @Html.RadioButtonFor(model => model.IsQuotedTariff, "No") <text>Notext>

                    @Html.ValidationMessageFor(model => model.IsQuotedTariff, "", new { @class = "text-danger" })

                div>

        div>

        <div class="form-group">

            <div class="col-md-offset-2 col-md-10">

And in controller

public ActionResult Index2(string IsQuotedTariff)

        {

            if (IsQuotedTariff.Equals("Yes"))

            {

                //first radio button selected

            }

            else if (IsQuotedTariff.Equals("NO"))

            {

                //second radio button selected

            }

            else

            {

                //nothing selected.

            }

            return View();

        }
