    <p>I have a ObservableCollection which holds records of custom type Item. I use that collection as a binding for a ListView in WPF. That class Item also implements the interface INotifyPropertyChanged. When I update some of the records in the ListView, I can see the change in the ListView. </p> <p>All this data comes from a WCF service. When I call the client object for the service and call a delete method to delete an item that belongs to the ObservableCollection, the record gets deleted in the DB but the items in the ListView are not updated. Is this how it is supposed to work, or should I remove the item from the collection manually when I delete it from the DB with the service call?</p> <p>Thanks</p> <p>Here is the XAML:</p> <pre><code>&lt;ListView ItemsSource="{Binding AllItems}" Height="244" IsSynchronizedWithCurrentItem="True" HorizontalAlignment="Left" Margin="1,25,0,0" Name="listView1" VerticalAlignment="Top" Width="485" &gt; &lt;ListView.ContextMenu&gt; &lt;ContextMenu AllowDrop="False"&gt; &lt;MenuItem Name="openRecord" Header="Open" Click="ContextMenuItem_Click" CommandParameter="{Binding RelativeSource={RelativeSource AncestorType=ContextMenu}, Path=PlacementTarget.SelectedItem}" /&gt; &lt;MenuItem Name="deleteRecord" Header="Delete" Click="ContextMenuItem_Click" CommandParameter="{Binding RelativeSource={RelativeSource AncestorType=ContextMenu}, Path=PlacementTarget.SelectedItem}" /&gt; &lt;/ContextMenu&gt; &lt;/ListView.ContextMenu&gt; &lt;ListView.ItemContainerStyle&gt; &lt;Style TargetType="{x:Type ListViewItem}"&gt; &lt;EventSetter Event="MouseDoubleClick" Handler="list_UserItems_ItemMouseDoubleClick" /&gt; &lt;/Style&gt; &lt;/ListView.ItemContainerStyle&gt; &lt;ListView.View&gt; &lt;GridView&gt; &lt;GridViewColumn DisplayMemberBinding="{Binding Title}" Header="Title" Width="200" /&gt; &lt;GridViewColumn DisplayMemberBinding="{Binding CreatedByName}" Header="Created By" Width="100" /&gt; &lt;GridViewColumn DisplayMemberBinding="{Binding CreatedOn}" Header="Created On" Width="100" /&gt; &lt;GridViewColumn DisplayMemberBinding="{Binding ExpirationDate}" Header="Expires" Width="100" /&gt; &lt;/GridView&gt; &lt;/ListView.View&gt; &lt;/ListView&gt; </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.
