Question

Below is my partial view call:

 <div id="div-reviewgrid">

                        @Html.Partial("_ReviewList", ViewBag.RewiewLists as List<Pollit.Data.Review>)

                    </div>

this is my partial view inside shared folder under Partial:

@using Pollit.Data;

@{
    List<Review> reviewList = ViewBag.RewiewLists;
}

<br /><br />

@if (reviewList != null)
{
    foreach (var review in reviewList)
    {
        <div class="col-lg-12">
            <div id="@review.Id">
                <div class="col-lg-1 col-md-1 col-xs-12 col-sm-12">
                    @if (review.Rating != null)
                    {
                        <img src="/images/ratings/@review.Rating.Number-bars.png" class="pull-left" style="max-height: 50px; max-width: 50px; margin-left: 30px" />

Answer 1

when you are calling your partial view the way you have written its wrong. each time you call it the new model is generating and your model goes empty`

@Html.Partial("_ReviewList", ViewBag.RewiewLists as List<Pollit.Data.Review>)

write Model instead of ViewBag.RewiewLists as List<Pollit.Data.Review>
