    <p>I have to upload selected files and display these files as links on post back. In my view I am adding each of the uploaded files as links using</p> <pre><code> @if (Model.IncidentLogInfoDetails.AttachmentCollection.AttachmentItemCollection.Any()) { foreach (EML.Container.Attachment attachmentItem in Model.IncidentLogInfoDetails.AttachmentCollection.AttachmentItemCollection) { @Html.ActionLink(attachmentItem.FileName, "testing") } } </code></pre> <p><strong>this is my controller action:</strong></p> <pre><code> public ActionResult UploadingFiles(HttpPostedFileBase imageFile) { // Converting to Attachment object Attachment fileAttachment = new Attachment(); fileAttachment.FileName = "imageFile.FileName"; fileAttachment.ContentType = imageFile.ContentType; fileAttachment.SizeInBytes = imageFile.ContentLength; using (MemoryStream ms = new MemoryStream()) { imageFile.InputStream.CopyTo(ms); fileAttachment.BinaryData = ms.GetBuffer(); } IncidentDetails incidentDetails = new IncidentDetails(); incidentDetails.IncidentLogInfoDetails = new IncidentLogInfo(); incidentDetails.IncidentLogInfoDetails.AttachmentCollection.AttachmentItemCollection = new List&lt;Attachment&gt;(); incidentDetails.IncidentLogInfoDetails.AttachmentCollection.AttachmentItemCollection.Add(fileAttachment); return View("FileUploadingTest", incidentDetails); } </code></pre> <p>My problem is that even though the loop is getting executed and Action links are created ( on debugging), they are not displayed after post back. <br>What am I missing ?</p>

    1. COMVC doesn't have "postback" - that's a WebForms concept that leverages ViewState.

    3. COWhen you said "Action links are created" do you mean to say that you have anchor tags (`<a>`) created on your view?

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.

SQuiL has stopped working due to an internal error.

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