Hi,
As stated on this site : http://stackoverflow.com/questions/7660967/wpf-error-cannot-find-govering-frameworkelement-for-target-element
"Sadly any DataGridColumn hosted under DataGrid.Columns is not part of Visual tree and therefore not connected to the data context of the datagrid. So bindings do not work with their properties such as Visibility or Header etc (although these properties are valid dependency properties!)."
The same way : LayoutAnchorables are not part of the VisualTree.
What you can do is apply the same solution :
```
<Grid>
<Grid.Resources>
<FrameworkElement x:Key="ProxyElement"
DataContext="{Binding}" />
</Grid.Resources>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<ContentControl Visibility="Collapsed"
Content="{StaticResource ProxyElement}" />
<TextBlock Grid.Row="1" Text="Usage:" Style="{StaticResource Header}" />
<xcad:DockingManager Grid.Row="2" MaxHeight="395"
AllowMixedOrientation="True"
BorderBrush="Black"
BorderThickness="1">
<xcad:LayoutRoot x:Name="_layoutRoot">
<xcad:LayoutRoot.LeftSide>
<xcad:LayoutAnchorSide>
<xcad:LayoutAnchorGroup x:Name="myGroup">
<xcad:LayoutAnchorable Title="{Binding DataContext.MyTitle, Source={StaticResource ProxyElement}}"
ContentId="agenda" IconSource="../Images/address-book-open.png">
<TextBlock Text="Agenda Content" Margin="10" FontSize="18" FontWeight="Black" TextWrapping="Wrap"/>
</xcad:LayoutAnchorable>
<xcad:LayoutAnchorable Title="Contacts" ContentId="contacts" IconSource="../Images/address-book--pencil.png" >
<TextBlock Text="Contacts Content" Margin="10" FontSize="18" FontWeight="Black" TextWrapping="Wrap"/>
</xcad:LayoutAnchorable>
</xcad:LayoutAnchorGroup>
</xcad:LayoutAnchorSide>
</xcad:LayoutRoot.LeftSide>
</xcad:LayoutRoot>
</xcad:DockingManager>
</Grid>
```
