IEnumerable<DocumentAttachment> is empty in my controller

Ben Murphy asked on August 22, 2019 13:00

I am using the standard method to get the properties of my page:

ClientLogosDatasource datasourceItem = ClientLogosDatasourceProvider.GetClientLogosDatasource(datasourceNodeGuid, "en-us", SiteContext.CurrentSiteName).Columns("ClientLogosDatasourceHeadingText", "ClientLogosDatasourceImages");

Which has an 'Attachments' form component

But when I attempt to enumerate over the property in my MVC application, the enumeration is empty.

Stepping through the code, it basically skips the foreach completely. I'm not sure why the Images property is null/empty.

Any help would be appreciated!

Here's the basic API example (not MVC specific) but should get you in the right direction.

// Creates a new instance of the Tree provider
TreeProvider tree = new TreeProvider(MembershipContext.AuthenticatedUser);

// Gets a page
TreeNode page = tree.SelectNodes()
    .Path("/Articles")
    .OnCurrentSite()
    .Culture("en-us")
    .TopN(1)
    .FirstOrDefault();

if (page != null)
{
    // Iterates over all attachments of the page
    foreach (DocumentAttachment attachment in page.AllAttachments)
    {
        // Perform any action with the attachment object (DocumentAttachment)
    }
}

// To get only unsorted attachments, use the TreeNode.Attachments collection
// To get only page field attachments, use the TreeNode.GroupedAttachments collection
