Have a docksite 'open' by default

Hi All

We're currently developing an application using the wpf studio, and we would like to have some/all of the docksite 'open' by default (i.e. auto-hide off). An example of the xaml is below. If anyone could point me to the relevant property I would be extrememly grateful.

<docking:DockSite.AutoHideBottomContainers>
<docking:ToolWindowContainer x:Name="ToolContainerLeft">
<docking:ToolWindow Title="Task Manager" x:Name="ToolWindowTaskManager">
<controls:TaskManagerControl />
</docking:ToolWindow>
</docking:ToolWindowContainer>
</docking:DockSite.AutoHideBottomContainers>

Many thanks

Mark
