    <p>I'm working in asp.net mvc 4 with Entity Framework 5 (with edmx). I'm trying to get Ninject to work correctly, but using the bindings has got me quite confused. I've seen Ninject being used before, but that was in a WCF project where the DI was being set in the WCF-layer.</p> <p>Right now I have 4 layers: </p> <ul> <li>DataAcces (contains edmx and repositories, which I will show later)</li> <li>BusinessLogic (standard BL)</li> <li>Common (models)</li> <li>Gui (a mvc4 project)</li> </ul> <p>Now here's the tricky part: I want to use DI here. The way I saw it being used in my previous WCF-project was that my WCF-layer went to my DataAccess so I can use the kernel.bind.<br /> Now I don't want that here. I'm not using WCF. I also don't want to call my DataAccess in my Gui.</p> <p>Since I said I'd show some code for insight:</p> <p>Repository in DataAccess</p> <pre><code>public class Repo: IRepo { Entities context = new Entities(); public IQueryable&lt;PictureSource&gt; PictureSource { get { return context.PictureSource; } } } </code></pre> <p>my IRepository is just this:</p> <pre><code>public interface IRepository { IQueryable&lt;PictureSource&gt; PictureSource { get; } } </code></pre> <p>What I want to be able to do is in my BusinessLogic. I want to be able to do the following:</p> <pre><code>public List&lt;Picture&gt; GetStuff(IRepository Repo) { //code } </code></pre> <p>Now I've looked a lot on the internet. About 80% of the examples use Web Apim which is useless to me. The other 20% just seem to do whatever they want "because it's just a demo" and violate Gui-BL-DA principle. I've seen examples consisting of a single layer to examples doing Business Logic in Data Access. The ninject wiki also didn't help me as I'm new to DI and I've only seen it being used in an existing application.</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.
