    <p>In my experience this code is not good, because you lose the capacity to navigate relationships through navigation properties. </p> <pre><code>public List&lt;Articles&gt; getArticles( ){ using (var db = new ArticleNetEntities()) { articles = db.Articles.Where(something).ToList(); } } </code></pre> <p>Using this approach you can't use the following code because a.Members is always null( db context is close and cant get data automatically). </p> <pre><code>var articles = Data.getArticles(); foreach( var a in articles ) { if( a.Members.any(p=&gt;p.Name=="miki") ) { ... } else { ... } } } </code></pre> <p>Using only a global db context is a bad idea because you must use a delete changes function</p> <p>in a point of your application yo do this but don't save changes and close the window</p> <pre><code>var article= globalcontext.getArticleByID(10); article.Approved=true; </code></pre> <p>then in another point of application you make some operation and save</p> <pre><code>//..... something globalcontext.saveChanges(); </code></pre> <p>in this case previous article approved property is set to modified by entity framework. When you save, approved is set true!!! </p> <p>Best approach for me is use 1 context per class You can pass context to another external method if you need</p> <pre><code>class EditArticle { private DbEntities de; private currentAricle; public EditArticle() { de = new DbEntities; //inizialize on new istance } loadArticleToEdit(Articele a){ // a is from another context currentArticle= de.Article.Single(p=&gt;p.IdArticle==a.IdArticle){ } private saveChanges(){ ... pe.saveChanges(); } } </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.
