Hi,
I'm having trouble getting an attachment that I used in a doctype.

What I have is a custom homepage, and in it, I can add any number of CarouselItems. I have a carousel item doctype.

This carousel item has several fields, among them an attachment which accepts an image to be uploaded.

I can get all fields values except for the attachment.

Here's my code. Please advise if possible.

Thanks in advance!

public partial class CMSTemplates_EntPartCanada_Homepage_Homepage : TemplatePage
{
    protected void Page_Load(object sender, EventArgs e)
    {
        // current pate is the parent of all carousel items
        var parent = CMSContext.CurrentDocument;

        // node data source
        var nodesDs = CMSContext.CurrentDocument.TreeProvider.SelectNodes(CMSContext.CurrentSiteName, parent.NodeAliasPath + "/%", null, true);
        if (nodesDs == null || nodesDs.Tables == null || nodesDs.Tables.Count == 0) return;

        // get carousel items
        var table = nodesDs.Tables[0];
        var carouselItems = new List<CarouselItem>();

        // take each carousel item entry...
        foreach (var carouselItemRow in table.Rows.Cast<DataRow>())
        {
            //... get the actual node
            var carouselItemNodeId = (int)carouselItemRow["nodeid"];
            var carouselItemNode = CMS.CMSHelper.CMSContext.CurrentDocument.TreeProvider.SelectSingleNode(carouselItemNodeId);

            // then get all properties
            carouselItems.Add(ProcessCarouselItem(carouselItemNode));
        }
    }

    private CarouselItem ProcessCarouselItem(CMS.TreeEngine.TreeNode node)
    {
        if (node == null) return null;

        var title = node.GetValue("title") as string;
        var description = node.GetValue("description") as string;
        var link = node.GetValue("link") as string;

        var image = node.GetValue("image"); // returns empty string

        // this doesn't work because the image node value is empty
        Guid attachmentGuid = ValidationHelper.GetGuid(image, Guid.Empty);
        string nodeAlias = ValidationHelper.GetString(node.GetValue("NodeAlias"), "");
        string fileUrl = ResolveUrl(AttachmentManager.GetAttachmentUrl(attachmentGuid, nodeAlias));
        // end code not working

        return new CarouselItem()
        {
            Description = description,
            Title = title,
            Link = link,
            Image = fileUrl
        };
    }
}
