The FlowDocument cannot be shared by several RichTextBox controls directly.. So you need to 'detach' that document first... So <pre><code>RTB2.Document = RTB1.Document; </code></pre> wont work and will result in your exception.. <pre><code>FlowDocument doc = RTB1.Document; RTB1.Document = new FlowDocument(); //Document cannot be null, so therefor the new FlowDocument instance RTB2.Document = doc; </code></pre> will work like a charm... My code sample: Xaml: <pre><code><Window x:Class="WpfApplication2.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition /> <ColumnDefinition /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <RichTextBox x:Name="RTB1" /> <RichTextBox x:Name="RTB2" Grid.Column="1" /> <Button x:Name="button" Grid.Row="1" Grid.ColumnSpan="2" Content="click" Click="button_Click" /> </Grid> </Window> </code></pre> Code behind.. <pre><code>public partial class Window1 : Window { public Window1() { InitializeComponent(); } private void button_Click(object sender, RoutedEventArgs e) { FlowDocument doc = RTB1.Document; RTB1.Document = new FlowDocument(); RTB2.Document = doc; } } </code></pre> Its not the prettiest in the book, but it works... Hope this helps..

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.
