    <p>In order to be able to sort the data automatically in the <code>DataGridView</code>, you need a collection that implements <code>IBindingListView</code>. In the BCL, the only classes that implement this interface are <code>DataView</code> and <code>BindingSource</code> (but the latter only supports sorting if the underlying datasource supports it too).</p> <p>So, you have several options:</p> <ul> <li>create a <code>DataTable</code> to hold the data, and bind it to the <code>DataGridView</code> (it will actually bind to the <code>DefaultView</code> of the <code>DataTable</code>)</li> <li>create your own collection class that implements <code>IBindingListView</code></li> <li><p>use an existing implementation, like the <code>AdvancedList&lt;T&gt;</code> class posted by Marc Gravell in <a href="http://www.eggheadcafe.com/software/aspnet/31429914/sort-a-bindinglist.aspx" rel="noreferrer">this post</a>. You will also need to add a constructor to build the list from the result of your query:</p> <pre><code>public AdvancedList(IEnumerable&lt;T&gt; collection) { foreach (var item in collection) { Add(item); } } </code></pre></li> </ul> <p>Since the result of your query is an anonymous type, you won't be able to call the constructor directly. The easiest way to work around the issue is to take advantage of type inference, by creating a generic method that will create the list. For convenience, you can create it as an extension method:</p> <pre><code>public static AdvancedList&lt;T&gt; ToAdvancedList&lt;T&gt;(this IEnumerable&lt;T&gt; source) { return new AdvancedList&lt;T&gt;(source); } </code></pre> <p>You can then use it like that:</p> <pre><code>dataGridView1.DataSource = _markets.Select(market =&gt; new { _cities[market.Location].Name, market.Value}).ToAdvancedList(); </code></pre>

    1. COVery good solution! My only complaint (and it is a small one) is that sorting isn't as fast as ideal, but it's tolerable and the best thing so far.

    2. COIt's slow because it uses reflection to get the property value. You could easily modify the PropertyComparer class so that it generates a delegate when it's created, and uses this delegate instead of property.GetValue

    3. CO@ThomasLevesque it would be great if you could post some code snippet to implement your suggestion. Thanks

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.
