    How to render multiple media picker items within a blocklist?

    Hi

    New to Umbraco and I want to be able to list a sort of document library using a block list so the user can add a title and then select a number of documents.

    I can display the title, but I'm a bit stuck on how to render the media picker items. I've used this code when having a single document library within a content page setting and was hoping I could just replace the model with the value, but it isn't working as I'm getting:

    cannot convert from 'method group' to 'object?'

    Many thanks

    @using ContentModels = Umbraco.Cms.Web.Common.PublishedModels;
        @{
            var content = (ContentModels.DocumentLibraryList)Model.Content;
        }

        <h3>@content.Value("title")</h3>
        <p>
    <h3>@content.Value("title")</h3>
    <p>
        @{var multiMediaPicker = @content.Value("documents");
            if (multiMediaPicker.Count() > 0){
            <h3>Document Library</h3>
            foreach(var item in multiMediaPicker)
            {
                <li><a href="@item.MediaUrl()">@item.Name</a></li>
            }
           }
        }
        </p>

    Hi Adamski

    I'm thinking when you use .Value that's fine for a string, but it's not telling the razor that your property is a more complex thing

    So I wonder if you have

       @{var multiMediaPicker = @content.Value<IEnumerable<MediaWithCrops>>("documents");

    whether that bit in the < > brackets will tell the code that it is a list of media items coming back, and therefore .Count() is a valid thing to call...

    regards

    Marc

    Thanks for the reply. However if I try that I get this error:

    The type or namespace name 'MediaWithCrops' could not be found (are you missing a using directive or an assembly reference?) Argument 1: cannot convert from 'method group' to 'object?'

    Edit: I've got it working :-) What I had to do was change it to this:

    var multiMediaPicker = content.Value<IEnumerable<IPublishedContent>>("documents").ToArray();

    and add to the top

    @using Umbraco.Cms.Core.Models.PublishedContent
