    <p>You need to first convert the data object to an <code>ItemDragEventArgs</code> and then retrieve the SelectionCollection from it, which contains the item you've dragged. Pass your <code>e</code> parameter to this method and it should return you the items dragged.</p> <p>I used an online C# to VB converter, so hopefully it did a good enough job. Both VB and C# below.</p> <p>VB:</p> <pre><code> using System.Windows.Controls; using System.Linq; using System.Collections.ObjectModel; using System.Collections.Generic; #if SILVERLIGHT using SW = Microsoft.Windows; #else using SW = System.Windows; #endif Private Function GetSelectedPeople(ByVal args As SW.DragEventArgs) As IEnumerable(Of Person)     Dim people As IEnumerable(Of Person) = Nothing         ' Retrieve the dropped data in the first available format.     Dim data As Object = args.Data.GetData(args.Data.GetFormats()(0))         ' The data is the ItemDragEventArgs that was created by the DDT when     ' the drag started. It contains a SelectionCollection.     ' SelectionCollection's are used by DDTs because they can transfer     ' multiple objects. The fact that they store the indexes of the     ' objects within the source collection also makes reordering items     ' within a source possible.     Dim dragEventArgs As ItemDragEventArgs = TryCast(data, ItemDragEventArgs)     Dim selectionCollection As SelectionCollection = TryCast(dragEventArgs.Data, SelectionCollection)     If selectionCollection IsNot Nothing Then         people = selectionCollection.[Select](Function(selection) selection.Item).OfType(Of Person)()     End If         Return people End Function </code></pre> <p>C#:</p> <pre><code> using System.Windows.Controls; using System.Linq; using System.Collections.ObjectModel; using System.Collections.Generic; #if SILVERLIGHT using SW = Microsoft.Windows; #else using SW = System.Windows; #endif private IEnumerable&lt;Person&gt; GetSelectedPeople(SW.DragEventArgs args) { IEnumerable&lt;Person&gt; people = null; // Retrieve the dropped data in the first available format. object data = args.Data.GetData(args.Data.GetFormats()[0]); // The data is the ItemDragEventArgs that was created by the DDT when // the drag started.

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.
