    <p>I have created an attached behavior that is used to execute a Delegate of type <code>Func&lt;bool&gt;</code> when the behavior is invoked. Below is the dependancy property definition.</p> <pre><code>public static readonly DependencyProperty SendToDetailBehaviorProperty = DependencyProperty.RegisterAttached("SendToDetailBehavior", typeof(Func&lt;bool&gt;), typeof(ListDetailAspectSendToDetailBehavior), new UIPropertyMetadata(null, SendToDetail)); </code></pre> <p>I have it working just as expected however in my XAML I get the following error, preventing the designer from loading.</p> <blockquote> <p>Property 'SendToDetailBehavior' was not found or is not serializable for type 'SortableListView'</p> </blockquote> <p>Below you will find the xaml.</p> <pre><code>&lt;Controls:SortableListView Grid.Row="0" Grid.Column="0" Name="lvwLocations" MinHeight="150" MinWidth="{Binding Path=BusinessObject.Locations, ValidatesOnDataErrors=true, Converter={StaticResource AlwaysReturn1Converter}, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}" Style="{DynamicResource SortableListViewStyle}" ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.HorizontalScrollBarVisibility="Auto" IsSynchronizedWithCurrentItem="True" **behaviors:ListDetailAspectSendToDetailBehavior.SendToDetailBehavior="{Binding Path=LocationListDetail.SendFocusToDetail}"** ItemsSource="{Binding Path=LocationListDetail.MasterList}" SelectedItem="{Binding Path=LocationListDetail.DetailItem, Mode=TwoWay}" MouseDoubleClick="lvwLocations_MouseDoubleClick"&gt; </code></pre> <p>If I change the underlying type of the Dependancy Property to a <code>bool</code> for example, the error goes away. </p> <p>As I said the attached behavior is working, only the designer blows up. I have looked for documentation on this and have come up empty. I am hoping someone here has some insight.</p> <p>Thanks, BDN</p>

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.
