After saving & loading my Docking Layout, the ToolWindowsTabPlacement settings set on a single ToolWindowContainer is lost and reset to Bottom. This is my XAML Code (I removed the contents and some event handlers for better readability):

<docking:DockSite x:Name="DockSite" 
                          Grid.Row="2"  
                          HorizontalAlignment="Stretch" 
                          VerticalAlignment="Stretch"
                          UseHostedAutoHidePopups="False"
                          CanDocumentWindowsRaft="True"
                          CanDocumentWindowsDragToLinkedDockSites="True"
                          AreDocumentWindowsDestroyedOnClose="False">
            <docking:DockSite.Switcher>
                <docking:StandardSwitcher AreToolWindowsVisible="False" />
            </docking:DockSite.Switcher>

            <docking:DockSite.ToolWindowTransitionSelector>
                <docking:ToolWindowTransitionSelector/>
            </docking:DockSite.ToolWindowTransitionSelector>

            <docking:DockSite.AutoHideRightContainers>
                <docking:ToolWindowContainer >
                    <docking:ToolWindow x:Name="PropertiesWindow" 
                                        Title="Properties">
                                        <!-- Snip -->
                    </docking:ToolWindow>
                </docking:ToolWindowContainer>
            </docking:DockSite.AutoHideRightContainers>
            
            <docking:SplitContainer Orientation="Vertical">
                <docking:SplitContainer>
                    <docking:ToolWindowContainer x:Name="ToolBoxContainer"
                                                 docking:DockSite.ToolWindowsTabPlacement="Top" 
                                                 docking:DockSite.ControlSize="330,0">

                        <docking:ToolWindow x:Name="ProjectExplorerWindow"
                                            Title="Project Explorer">
                            <!-- Snip -->
                        </docking:ToolWindow>

                        <docking:ToolWindow x:Name="RepositoryExplorerWindow"
                                            Title="Repository Explorer">
                            <!-- Snip -->
                        </docking:ToolWindow>

                        <docking:ToolWindow x:Name="DocumentOutlineWindow" 
                                            Title="Document Outline">
                            <!-- Snip -->
                        </docking:ToolWindow>

                        <docking:ToolWindow x:Name="ToolboxWindow"
                                            Title="Toolbox">
                            <!-- Snip -->
                        </docking:ToolWindow>
                        
                    </docking:ToolWindowContainer>

                    <docking:Workspace>
                        <docking:TabbedMdiHost x:Name="DocumentsHost"
                                               IsImageOnTab="True"
                                               CanDocumentsCloseOnMiddleClick="True">
                            <docking:TabbedMdiContainer x:Name="DocumentsContainer" 
                                                        SelectionChanged="DocumentsContainer_SelectionChanged"
                                                        TabOverflowBehavior="ShrinkWithMenu">
                                <docking:DocumentWindow x:Name="StartPageWindow"
                                                        Title="Start Page">
                                                        <!-- Snip -->
                                </docking:DocumentWindow>
                            </docking:TabbedMdiContainer>
                        </docking:TabbedMdiHost>
                    </docking:Workspace>
                </docking:SplitContainer>

                <docking:ToolWindowContainer>
                    <docking:ToolWindow x:Name="ScriptrunresultsWindow" 
                                        Title="Script Run Results">
                        <!-- Snip -->
                    </docking:ToolWindow>
                </docking:ToolWindowContainer>
            </docking:SplitContainer>
            
        </docking:DockSite>

 Note that the "ToolBoxContainer" has the ToolWindowsTabPlacement set to Top.

Serializing this Layout leads to this XML:

<DockSiteLayout xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" SerializationFormat="ToolWindowsOnly">

	</ToolWindows>
</DockSiteLayout>

 And finally, after loading the XML using this code:

new DockSiteLayoutSerializer().LoadFromString(layout, DockSite);

 Everything is restored correctly, but the Tabs of "ToolBoxContainer" are now on the bottom side.

 

I noted that I can warkaround this issue by setting the ToolWindowsTabPlacement Option on the DockSite itself, but then all Tabs of all ToolWindowContainers are on the top. Which isn't too bad, but this should be saved & loaded correctly nonetheless.

 

Best Regards

Hi Markus,

That actually is by design.  You should never be setting properties directly on "containers" since they are created/destroyed dynamically as the user moves docking windows around the layout.  For instance if the user dragged all the tool windows out of the container where you set that property directly, that container might get destroyed and then if the tool windows were docked again together elsewhere, they would not have tabs on top.

As you saw, you should instead be setting DockSite.ToolWindowsTabPlacement to manage the tab placement settings for tool windows.  That will provide consistency across all the tool windows.
