Steps to Reproduce:

Press CodeRush key on the caret pos:

@functions{

    private bool? <caret>Value {

        get {

            if (ViewData.Model == null) {

                return null;

            }

            return Convert.ToBoolean(ViewData.Model, System.Globalization.CultureInfo.InvariantCulture);

        }

    }

}

<div class="display_item">

    <strong>@ViewData.ModelMetadata.DisplayName</strong>

    @if (ViewData.ModelMetadata.IsNullableValueType) {

        <select class="list-box tri-state" disabled="disabled">

            <option value=""@(Value.HasValue ? null : " selected='selected'")>Not Set</option>

            <option value="true"@(Value.HasValue && Value.Value ? " selected='selected'" : null)>True</option>

            <option value="false"@(Value.HasValue && !Value.Value ? " selected='selected'" : null)>False</option>

        </select>

    } else {

        <input type="checkbox" class="check-box" disabled="disabled"@(Value.HasValue && Value.Value ? " checked='checked'" : null) />

    }

</div>
