How to restore content on loading layout

[Sputnik24]

I use the concept of DemoXaml in the samples to save the layout on closing the app and loading it on startup. The layout is stored and restored perfectly, but the content is lost. Same happens with DemoXaml.

How can I restore/add the content after loading the layout using

var layout = new DockSerializer(typeof(ObservableCollection<>)).Load<IDock>("layout.json");
dock.Layout = layout;

I tried something like

var tool = this.Find<Tool>("ToolName");
tool.Content = new ToolNameView();

where ToolNameView is a UserControl which was added in the MainWindows.axaml using ViewLocator like:

<ToolDock x:Name="LeftPane" Id="LeftPane" Proportion="0.67">
    <Tool x:Name="ToolName" Id="ToolName" Title="Tool Name" x:DataType="ToolDock" CanFloat="False" CanClose="False">
        <UserControl Content="{Binding $parent[Window].DataContext.ToolNameViewModel}" />
    </Tool>
</ToolDock>

But this does not work.

It's not yet implemented for Xaml defined layouts.

@wieslawsoltes Thanks for your quick reply. Does it mean it works with code defined layouts?
