    <p>Sorry if somebody has already asked this question. I've been looking around but couldn't find anything related.</p> <p>So, I am using Entity Framework and I am trying to load the list of "Idiomas" from the dataset using the ToList method through the following code:</p> <pre><code>//List&lt;Idioma&gt; ans = new List&lt;Idioma&gt;(contexto.Idiomas); return contexto.Idiomas.ToList(); </code></pre> <p>However, the method is returning an empty list, even though I can see through the debugger that the DataSet has elements. </p> <p><strong>EDIT</strong></p> <p>I have not put any extra code because there is not any extra code besides those two lines. I just create a Entity Framework model-first, generated the database, and updated the model from the database to make sure everything was ok. </p> <p>Contexto is a instance from the class LivroContexto, which implements DbContext (auto generated by vs2012, see below).</p> <p>LivroContainer:</p> <pre><code>public partial class LivroContainer : DbContext { public LivroContainer() : base("name=LivroContainer") { } protected override void OnModelCreating(DbModelBuilder modelBuilder) { } public DbSet&lt;Idioma&gt; Idiomas { get; set; } } </code></pre> <p>Idiomas:</p> <pre><code>public partial class Idioma { public Idioma() { this.Traducaos = new HashSet&lt;Traducao&gt;(); } public int IdIdioma { get; set; } public string Lingua { get; set; } public virtual ICollection&lt;Traducao&gt; Traducaos { get; set; } } </code></pre> <p>Thank you</p>

    2. COContexto in this case is the auto generated container for the entity framework (generated through the edmx file in vs2012).

    3. COAssuming that you are indeed using the Entity Framework, that `contexto` is your object context, and Idiomas is a property encapsulating a table or view, this sounds impossible. Then again, in the assumed scenario, there wouldn't be any DataSets, certainly not any that have elements.

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.
