<p>The problem has been solved!</p> <p><strong>Summary:</strong> After a day of problems and research for the solution it turned out to be something extreamly simple. Since we are creating entries to the sql database, we expose properties of a model to the view that we expect to be used by the user. </p> <p>We were getting a single error causing the ModelState.IsValid to be false. The error was always the same, "[PrimaryKeyId] field is required". </p> <p><strong>Solution:</strong> In our views (.cshtml) we were exposing the primary key property but marking it as hidden. Apparently when you do this, the validation/checking of the model that EF does must check saying, to the effect, if the property is exposed in the view mark it as required and since it is never updated due to it being hidden it gets the default int value on 0, which is not valid as an identifier.</p> <p><strong>This is what the code was</strong></p> <pre><code><div class="bg-white content-inner"> @Html.HiddenFor(model => model.PrimaryKeyId)//BAD DO NOT DO THIS <div class="row-fluid"> <div class="span4"> @Html.LabelFor(model => model.GroupName) </div> <div class="span4 offset2"> @Html.TextBoxFor(model => model.GroupName) @Html.ValidationMessageFor(model => model.GroupName) </div> </div> </code></pre> <p>Now without the property within the model we get this:</p> <p>NO ERRORS AND A VALID MODELSTATE! <img src="https://i.stack.imgur.com/Y3t2a.png" alt="NO ERRORS"></p> <p><img src="https://i.stack.imgur.com/PfcP5.png" alt="VALID MODEL STATE"></p> <p>Given that I am still learning about EF and MVC this turned out to be a tough learning experience, but definatly a mistake I won't make again. Hope this can help! </p> <p>Thanks to all gave me advice and helped.</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.
