Problem rendering multi media picker in version 7.2.8

I am having problems rendering images with the multi media picker. I'm using version 7.2.8 which is a little older than I'm used to and I noticed I need to use 'umbraco:Macro runat="server" language="cshtml"' outside the razor call. For some reason "/umbraco:Macro" part of that tag is highlighted red so I know I'm doing something wrong. Here is what I have tried along with different variations.

                    <umbraco:Macro runat="server" language="cshtml">                    
                    @{
                        var typedMultiMediaPicker = Model.Value<IEnumerable<IPublishedContent>>("largeCarousel");
                        foreach (var item in typedMultiMediaPicker)
                        {
                            <div class="carousel-item"><img src="@item.Url" alt="image3" class="image imageLarger" align="bottom"></div>
                        }
                    }
                    </umbraco:Macro>

Hi Andrew,

I think in version 7.2.8 Model.Value<>

Probably it should be:

var calouselMediaIds = UmbracoHelper.AssignedContentItem.GetPropertyValue<IEnumerable<int>>("largeCarousel");

In this array, you will have an array with ids.

Then You can get image with this code:

foreach (var mediaId in calouselMediaIds)
                        {
var mediaItem = Umbraco.TypedMedia(mediaId);
  <div class="carousel-item"><img src="@mediaItem.Url" alt="image3" class="image imageLarger" align="bottom"></div>
}

Thanks,

Alex

Thank you for the help I tried using this method and I get this error. Do I need a certain using statement for this to work?

Try to use just Umbraco instead UmbracoHelper, like this:

var calouselMediaIds = Umbraco.AssignedContentItem.GetPropertyValue<IEnumerable<int>>("largeCarousel");

Thank you for your quick response that did not work either I get this error now "CS0234: The type or namespace name 'AssignedContentItem' does not exist in the namespace 'Umbraco' (are you missing an assembly reference?)" enter image description here

Umbraco should not be a namespace. Can you show me all your code?

What about first line? it looks like missing @inherits section

I'm not sure what inherits I would need. All the other pages on this site don't use any. They do use this <%@ Master Language="C#" MasterPageFile="~/umbraco/masterpages/default.master" AutoEventWireup="true" %> but I think that is just for the nav, but this page doesn't use that because it's its own thing and not part of the main website

Ah, so you use WinForms solution, not a razor, it changes the game

I ended up making it a macro and modifying the code a little but this is the macro I made if anyone has the same problem.

@{
    var currentPage = Umbraco.TypedContent(UmbracoContext.Current.PageId);
    var typedMultiMediaPicker = currentPage.GetPropertyValue("largeCarousel");
    if (typedMultiMediaPicker != null)
    {
        foreach (var item in typedMultiMediaPicker.ToString().Split(','))
        {
            var img = Umbraco.TypedMedia(item);
            <div class="carousel-item active"><img src="@img.Url" alt="image3" class="image imageLarger" align="bottom"></div>              
        }
    }
}

I use this line of code to call the macro in my template

   <umbraco:Macro Alias="LargeCarousel" runat="server" />
