HTML Helpers

@foreach (var item in Model)
{
    <div class="review">
        <h4>@item.Name</h4>
        <span>@item.Rating</span>
        <p>@item.City, @item.Country</p>

        <span class="right">
            @Html.ActionLink("Edit", "Edit", new { id = item.Id })
        </span>
    </div>
}

Форма

@using (Html.BeginForm()) {
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)

    <fieldset>
        <legend>RestaurantReview</legend>

        @Html.HiddenFor(model => model.Id)

        <div class="editor-label">
            @Html.LabelFor(model => model.Name)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Name)
            @Html.ValidationMessageFor(model => model.Name)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.City)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.City)
            @Html.ValidationMessageFor(model => model.City)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Country)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Country)
            @Html.ValidationMessageFor(model => model.Country)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Rating)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Rating)
            @Html.ValidationMessageFor(model => model.Rating)
        </div>

        <p>
            <input type="submit" value="Save" />
        </p>
    </fieldset>
}

Partial Views

Соглашение о названии - начинается с нижнего подчеркивания _Review.cshtml

@model OdeToFood.Models.RestaurantReview

<div class="review">
    <h4>@Model.Name</h4>
    <span>@Model.Rating</span>
    <p>@Model.City, @Model.Country</p>

    <span class="right">
        @Html.ActionLink("Edit", "Edit", new { id = Model.Id })
    </span>
</div>

Использование

@foreach (var item in Model)
{
    @Html.Partial("_Review", item)
}

2 способ

@Html.Action("BestReview", "Reviews");

Вызывает экшен (1 параметр) из контроллера (2 параметр)

Определяем метод в контроллере Reviews

public ActionResult BestReview()
        {
            var bestReview = from r in _reviews
                             orderby r.Rating descending
                             select r;
            return PartialView("_Review", bestReview.First());
        }

Атрибут [ChildActionOnly] делает невозможным вызов публичного метода напрямую

        [ChildActionOnly]
        public ActionResult BestReview()
        {
            var bestReview = from r in _reviews
                             orderby r.Rating descending
                             select r;
            return PartialView("_Review", bestReview.First());
        }
