    <p>i have two ListBoxes (in a Silverlight 3 Application), each wrapped with a ListBoxDragDropTarget. Now i fill the SourceBox with some custom Objects (Person). Then i wire up the DragOver Event of the Destination DragDtopTarget. This all workd fine and i can drag &amp; drop the elements from the first list to the second.</p> <p>Now my issue: How can i get the Element, which is being dragged to allow/disalow dragging? (I cannot get the Person from the FragEventArgs).</p> <p>This is my Xaml:</p> <pre><code>&lt;Grid x:Name="LayoutRoot" Background="White"&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition Width="*"/&gt; &lt;ColumnDefinition Width="*"/&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;controlsToolkit:ListBoxDragDropTarget HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" x:Name="DragSource"&gt; &lt;ListBox x:Name="lbSource" DisplayMemberPath="Name" /&gt; &lt;/controlsToolkit:ListBoxDragDropTarget&gt; &lt;controlsToolkit:ListBoxDragDropTarget Grid.Column="1" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" x:Name="DragDest" msWindows:DragDrop.AllowDrop="true"&gt; &lt;ListBox x:Name="lbDest" DisplayMemberPath="Name" /&gt; &lt;/controlsToolkit:ListBoxDragDropTarget&gt; </code></pre> <p></p> <p>and this is the Code of my DragOver-Handler:</p> <pre><code>Private Sub DragDest_DragOver(ByVal sender As Object, _ ByVal e As Microsoft.Windows.DragEventArgs) _ Handles DragDest.DragOver Dim Pers = e.Data.GetData(GetType(Person)) End Sub </code></pre> <p>Thank you for any hints how to solve this.</p> <p>Christoph</p> <p>EDIT:</p> <p>This is my short version of the Answer :-) :</p> <pre><code>Private Sub DragDest_DragOver(ByVal sender As Object, _ ByVal e As Microsoft.Windows.DragEventArgs) _ Handles DragDest.DragOver Dim Args As ItemDragEventArgs = e.Data.GetData(e.Data.GetFormats()(0)) Dim Sel As SelectionCollection = Args.Data Dim Persons = (From Pe In Sel Select DirectCast(Pe.Item, Person)).ToList End Sub </code></pre>

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.
