Hi Srinvias,

You could easily remove the desired background, setting Background property to the RadPaneGroup element of RadDocking control. To remove the border, you should modify inside the control template of RadPaneGroup style. Inside Expression Blend right-click of the RadPaneGroup in Objects and Timeline, select Edit Template -> Edit a Copy and it will generate the style of RadPaneGroup.
Look for

<Border x:Name="BorderLayer3" BorderBrush="White" BorderThickness="2" CornerRadius="0,1,1,1">
    <Border x:Name="BorderLayer2" BorderBrush="#FFF0F0F0" BorderThickness="2" CornerRadius="0">
        <Border x:Name="BorderLayer1" BorderBrush="#FF848484" BorderThickness="1" CornerRadius="0">
            <ContentPresenter ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentStringFormat="{TemplateBinding ContentStringFormat}"/>
        </Border>
    </Border>
</Border>

inside DocumentHostTemplate setter and modify the borders of your choice. Please note you man need to apply the same changes to the BottomTemplate and to the TopTemplate, if you wish to have the same look of all RadDocking positions.

The attached project demonstrates the described scenario. I hope this will be helpful.
