Hello,

Thank you for your post. I have been looking through it and i suggest you use the following Style for the PaneHeaderPresenter:

            <Style TargetType="{x:Type igDock:PaneHeaderPresenter}">
                <Style.Triggers>
                    <DataTrigger Binding="{Binding Path=IsKeyboardFocused}"  Value="True">
                        <Setter Property="Background" Value="YellowGreen"/>
                    </DataTrigger>
                </Style.Triggers>
            </Style>

Please let me know if this meets your reuirements.

Looking forward fort your reply.
