    <p>I have a static <code>ObservableCollection</code> MarketList in ViewModel and it is bound to <code>Table</code> in following manner:</p> <pre><code>&lt;FlowDocumentScrollViewer Height="216" VerticalAlignment="Top" Margin="-7,2,7,0" &gt; &lt;FlowDocument&gt; &lt;Table CellSpacing="0" Name="MBPTable" &gt; &lt;Table.DataContext&gt; &lt;MultiBinding UpdateSourceTrigger="Explicit" Mode="TwoWay" Converter="{StaticResource indexerConverter}"&gt; &lt;Binding Path="MarketList" UpdateSourceTrigger="PropertyChanged" NotifyOnSourceUpdated="True" Mode="TwoWay" BindsDirectlyToSource="True" /&gt; &lt;Binding Path="MBPindex" Mode="TwoWay" /&gt; &lt;/MultiBinding&gt; &lt;/Table.DataContext&gt; &lt;Table.Resources&gt; &lt;local:IndexerConverter x:Key="indexerConverter"&gt;&lt;/local:IndexerConverter&gt; &lt;/Table.Resources&gt; </code></pre> <p><code>Table</code> contains <code>ListView</code> which is bound to Property of MarketList.</p> <pre><code>&lt;ListView Name="MarketByPriceList" Width="300" ItemsSource="{Binding MarketByPriceList, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" AlternationCount="2" Margin="0,15,0,0" &gt; &lt;ListView.View&gt; &lt;GridView&gt; &lt;GridViewColumn Header="Orders" Width="48" DisplayMemberBinding="{Binding MBP_NoofBuy_Orders, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" &gt;&lt;/GridViewColumn&gt; &lt;GridViewColumn Header="Bid Qty" Width="48" DisplayMemberBinding="{Binding MBPBID_Qty, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" &gt;&lt;/GridViewColumn&gt; &lt;/GridView&gt; &lt;/ListView.View&gt; &lt;/ListView&gt; </code></pre> <p>This Is Convertor Method</p> <pre><code> public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture) { if (values != null &amp;&amp; values[0] != DependencyProperty.UnsetValue) { // ObservableCollection&lt;GlobalItems.Model.MarketWatchModel&gt; allNames = (ObservableCollection&lt;GlobalItems.Model.MarketWatchModel&gt;)values[0]; int index = (int)values[1]; return GlobalItems.ViewModel.MarketWatchModelView.MarketList[index]; } else { return null; } } </code></pre> <p>Binding works fine but update in collection is not reflected in UI</p>

    1. COIs the collection being updated from the UI thread? If not I don't think you'll see the changes.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
