I've created an avalon dock interface in my project, I want to interact with a LayoutAnchorableItem property "Visibility" for example but how implement it into my XAML code ? I couldn't have two Style definitions into my DockingManager.LayoutItemContainerStyle branch...

The line I want to add:

```
<Setter Property="Visibility" Value="{Binding Model.IsVisible, ConverterParameter={x:Static Visibility.Hidden}, Converter={StaticResource btvc}, Mode=TwoWay}" />

```

My original XAML code:

```
<dock:DockingManager DataContext="{Binding DockManagerViewModel}" DocumentsSource="{Binding Documents}" AnchorablesSource="{Binding Anchorables}" >
    <dock:DockingManager.Resources>
    <!-- add views for specific ViewModels -->
        <DataTemplate DataType="{x:Type vmdock:SampleDockWindowViewModel}">
            <uscontrol:SampleDockWindowView />
        </DataTemplate>
    </dock:DockingManager.Resources>
    <dock:DockingManager.LayoutItemContainerStyle>
    <!--you can add additional bindings from the layoutitem to the DockWindowViewModel-->
        <Style TargetType="{x:Type dockctrl:LayoutItem}">
            <Setter Property="Title" Value="{Binding Model.Title}" />
            <Setter Property="CloseCommand" Value="{Binding Model.CloseCommand}" />
            <Setter Property="CanClose" Value="{Binding Model.CanClose}" />
            <Setter Property="IsSelected" Value="{Binding Model.IsSelected}" />
        </Style>
    </dock:DockingManager.LayoutItemContainerStyle>

```

Thanks a lot !
