Hi guys,

I've got a sliding banner that I'm having issues with. It's working correctly on my dev site but the pre go live site with an identical partial view is not setting an active item where the item IsFirst.

Using Umbraco 7.1.6

This is my code:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
    @using Our.Umbraco.PropertyConverters.Models

    @{
        var root = Model.Content.GetPropertyValue<string>("sectionName");
        var promoItems = Umbraco.ContentAtXPath("//PromoItem").Where("Visible");
}


<div id="myCarousel" class="carousel slide"> 
    <div class="carousel-inner">
        @foreach (var item in promoItems)
  {
  if  (item.GetPropertyValue<string>("siteAssignedTo") == root || (item.GetPropertyValue<string>("siteAssignedTo") == "All"))
  {
        <div class="@item.IsFirst("active") item">
            <div class="slide">
                <img src="@item.GetCropUrl("image","promoHome")" alt="@item.Name" />
                    <div class="promoinfo">
                     <a href="@item.GetPropertyValue("link").Url" class="btn btn-primary"><h3>@item.GetPropertyValue("Description")</h3></a>
                </div>
            </div>
        </div>
        }
        }
    </div>
    <!-- Carousel nav -->
        <div class="carousel-control">
    <a class="carousel-control left" href="#myCarousel" data-slide="prev"><span class="glyphicon glyphicon-chevron-left"></span></a>
    <a class="carousel-control right" href="#myCarousel" data-slide="next"><span  class="glyphicon glyphicon-chevron-right"></span></a>
        </div>
</div>

Any help would be much appreciated :)

Hi Richard,

You will need to use the ToContentSet method, this was a breaking change in v7.1 and v6.2 which I documented here

e.g.
```
@foreach (var item in promoItems.ToContentSet())
```

Hi Jeavon,

I've just tried that and it's made no difference :(

I've tried a condition instead but this works for the dev site but not the pre live site. I have cleared the App_Data folder and recycled the web app but with no joy.

New code:

    @inherits Umbraco.Web.Mvc.UmbracoTemplatePage
        @using Our.Umbraco.PropertyConverters.Models

        @{
            var root = Model.Content.GetPropertyValue<string>("sectionName");
            var promoItems = Umbraco.ContentAtXPath("//PromoItem").Where("Visible");
    }


    <!--promo slider html-->
    <div id="myCarousel" class="carousel slide"> 
        <div class="carousel-inner">
            @{int count = 0;
              string activeclass = "";}
            @foreach (var item in promoItems)
      {
          if (count == 0)
            {
                activeclass = "active item";
                count++;
            }
            else
            {
                activeclass = "item";
            }
      if  (item.GetPropertyValue<string>("siteAssignedTo") == root || 
          (item.GetPropertyValue<string>("siteAssignedTo") == "All"))
      {
            <div class="@activeclass">
                <div class="slide">
                    <img src="@item.GetCropUrl("image","promoHome")" alt="@item.Name" />
                        <div class="promoinfo">
<a href="@item.GetPropertyValue("link").Url" class="btn btn-primary">
<h3>@item.GetPropertyValue("Description")</h3></a>
                    </div>
                </div>
            </div>
            }
            }
        </div>
        <!-- Carousel nav -->
            <div class="carousel-control">
        <a class="carousel-control left" href="#myCarousel" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span></a>
        <a class="carousel-control right" href="#myCarousel" data-slide="next">
<span  class="glyphicon glyphicon-chevron-right"></span></a>
            </div>
    </div>
    <!--end promo slider html-->
