    <p>So we have a number of tables in our edmx, 13, that we created from an existing sql database. When we try to add a new entry to the tables through the UI we built, it fails on all but 4 of them. </p> <p>Doing some digging we found out the the ModelState actually comes back as false and it is because we get an error that states "The [PrimaryKeyId] field is required". I don't understand what would be causing this issue when some of the tables are working just fine when we add new data. </p> <p><img src="https://i.stack.imgur.com/Z5Qn6.png" alt="enter image description here"></p> <p>In the edmx we looked at the properties of the primary keys of the tables and everything seems right</p> <p><img src="https://i.stack.imgur.com/UTms2.png" alt="enter image description here"></p> <p>I feel like there could have been an issue when scaffolding the tables. I cannot be sure, I am still learning the intricacies of EF.</p> <p>Can anyone point me in the right direction? Could this be something on the SQL side (personaly don't think it is as we already added data in these tables through sql scripts)? Could it be EF? Should I blow the edmx tables again and re-add them? I am feeling lost. Thanks for the help!</p> <p><strong>EDIT 1</strong></p> <p>So because we used the Entity Framework Scaffolding we have the basic methods. This is the create method with a few properties being manually set. Also the Primary Keys in the db are auto incrementing.</p> <pre><code>[HttpPost] [ValidateAntiForgeryToken] public ActionResult Create(Entity entity) { if (ModelState.IsValid) { _user = GetUser(); entity.CreateDate = DateTime.Now; entity.LastUpdateDate = DateTime.Now; entity.LastUpdatedById = _user.Id; entity.CreatorId = _user.Id; db.Entities.Add(entity); db.SaveChanges(); return RedirectToAction("Index"); } return View(entity); } </code></pre>

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.
