Hi Frank,
We could use DockingManager.SetAutoHideMode() method to resolve this. We could call SetAutoHideMode in NewDockStateEndLoad event handler. NewDockStateEndLoad method is fired after the initialization of DockingManager.
[C#]
private void dockingManager1_NewDockStateEndLoad(object sender, System.EventArgs e)
{
this.dockingManager1.SetAutoHideMode( this.panel1 , true );
}
[Sample]
