I tried the following code but i'm not able to have a navigation bar automatically resizing its parent when it is minimized (i.e. the splitcontainer). Is there a solution to this problem ? Thanks.
<docking:DockSite Name="DockSite">
<docking:SplitContainer Orientation="Horizontal">
<docking:ToolWindowContainer>
<docking:ToolWindow>
<navigation:NavigationBar x:Name="NB">
(...)
</navigation:NavigationBar>
</docking:ToolWindow>
</docking:ToolWindowContainer>
<docking:Workspace>
(...)
</docking:Workspace>
</docking:SplitContainer>
</docking:DockSite>
