EpiServer: Get IDs of items in content area

I'm workin on a view (Razor) of a block (blockA). This block contains a ContentArea called solutions. I would like to get a list as a string of the IDs of the items in solutions.

I have tried looking in @Model.Solutions.FilteredItems. or @(((IContent)Model).ContentLink. to see if I can access a list of the IDs of all the items.

How can I get the IDs of all items in solutions as a string list?

Solution

  • You'll find the ID in the ContentLink of the ContentAreaItem, no need to cast

    To output as a comma separated list,

    // always null check contentareas in templates
var idList = Model.ContentArea != null && Model.ContentArea.FilteredItems.Any() ? string.Join(",", Model.ContentArea.FilteredItems.Select(x => x.ContentLink.ID)) : "";

<div>@idList</div>

    To write it out as a list

    @if (Model.ContentArea != null && Model.ContentArea.FilteredItems.Any())
{
    <ul>
        @{
            foreach (var item in Model.ContentArea.FilteredItems)
            {
                <li>@item.ContentLink.ID</li>
            }
        }
    </ul>
}
