I'm developing a project using Silverlight 4 and Entity Framework 4 and I'm trying to auto-load the details (with conditions) associated with an entity when the client loads the EntityQuery. So far, I've been able to put in place a solution, using the Include attribute, that returns all the details associated with the master entity. What I'm missing here is to be able to filter out the details based on some criteria. As an example, here's what my entities look like: Entity Movie <pre><code>Id (int) [Include] MovieLocalizedInformations (EntityCollection<MovieLocalizedInformation>) </code></pre> Entity MovieLocalizedInformation <pre><code>Id (int) Movie_Id (int) LanguageCode (eg.: en) Title </code></pre> On my DomainService object, I expose the following method: <pre><code>public IQueryable<Movie> GetMovies( string languageCode ) { return this.ObjectContext.Movies.Include( "MovieLocalizedInformations" ); } </code></pre> This works fine. But when I try to add where clause to filter out the localized information based on the language code, only the movies get loaded on the client. Is there a way to achieve the filtering in one query? Note: I'm also using the DomainDataSource with paging on the client so the solution needs to work with that. Any help would be greatly appreciated! Thanks, Jacques.

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.
