    <p>I have the following base methods:</p> <pre><code>public IQueryable&lt;T&gt; All { get { return Context.DataSet&lt;T&gt;(); } } public IQueryable&lt;T&gt; Search(Func&lt;T, bool&gt; where) { return this.All.Where(where); // compiling error, since it returns IEnumerable by default. Why not returning IQueryable? } </code></pre> <p>However, when i use the 'All' property in in my service class, it resolves as IQueryable</p> <pre><code>private List&lt;CustomerDomainModel&gt; PrepareBaseResultingData(int id) { IQueryable&lt;CustomerDomainModel&gt; custs = _customerRepository.All.Where(c =&gt; c.ID == id); // it returns IQueryable by default so it is good! return custs.ToList(); } </code></pre> <p>is there any reasons why the "Where clause" extension method returning either IEnumerable or IQuaryable?</p> <p><strong>Edited question:</strong></p> <p>why does the Search method have compiling error? I would've expected that "this.All.Where(where)" would return IQueryable</p>

    1. COI'm confused. Your property is typed as `IQuerably<All>`... what do you expect from it?

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.
