    <p>I have two classes like so:</p> <pre><code>public class SentEmailAttachment : ISentEmailAttachment { public SentEmailAttachment(); public string FileName { get; set; } public string ID { get; set; } public string SentEmailID { get; set; } public string StorageService { get; set; } public string StorageServiceFileID { get; set; } } </code></pre> <p>And</p> <pre><code>public class SentEmailAttachmentItem : ISentEmailAttachment { [ItemName] public string ID { get; set; } public string SentEmailID { get; set; } public string FileName { get; set; } public string StorageService { get; set; } public string StorageServiceFileID { get; set; } } </code></pre> <p>Identical, as you can see (they both implement interface to ensure this)</p> <p>I then have the following mapping:</p> <pre><code>Mapper.CreateMap&lt;IEnumerable&lt;SentEmailAttachmentItem&gt;, IEnumerable&lt;SentEmailAttachment&gt;&gt;(); Mapper.CreateMap&lt;IEnumerable&lt;SentEmailAttachment&gt;, IEnumerable&lt;SentEmailAttachmentItem&gt;&gt;(); </code></pre> <p>I then have the following Unit test:</p> <pre><code>//create a load of sent email attachments var listOfSentEmailAttachments = new List&lt;SentEmailAttachment&gt;(); for (int i = 0; i &lt; 10; i++) listOfSentEmailAttachments.Add(new SentEmailAttachment { FileName = "testFileName", ID = Guid.NewGuid().ToString(), SentEmailID = Guid.NewGuid().ToString(), StorageService = "S3", StorageServiceFileID = "SomeFileID" }); var sentEmailAttachmentItems = Mapper.DynamicMap&lt;IEnumerable&lt;SentEmailAttachment&gt;, IEnumerable&lt;SentEmailAttachmentItem&gt;&gt;(listOfSentEmailAttachments); var itemToTest = sentEmailAttachmentItems.First(); Assert.IsInstanceOfType(itemToTest, typeof(SentEmailAttachmentItem)); </code></pre> <p>This fails - The IEnumerable sentEmailAttachmentItems is empty. It didn't map the list of SentEmailAttachments to it...</p> <p>Any idea what's going on??</p> <p>I have it working on single objects (mapping one of each to one of each) but not a collection...</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
