Hi YYZRichard,

A possible solution is to edit the Default Style of the RadTabItem like so:

<UserControl.Resources>

<Thickness x:Key="TabItem_OuterBorderThickness">1 1 1 0</Thickness>

<SolidColorBrush x:Key="ControlForeground_Normal" Color="#FF000000"/>

<SolidColorBrush x:Key="TabItem_Background_Normal" Color="Transparent"/>

<SolidColorBrush x:Key="TabItem_OuterBorder_Normal" Color="Transparent"/>

<SolidColorBrush x:Key="TabItem_InnerBorder_Normal" Color="Transparent"/>

<Thickness x:Key="TabItem_InnerBorderThickness">1 1 1 0</Thickness>

<CornerRadius x:Key="TabItem_InnerCornerRadius">2 2 0 0</CornerRadius>

<CornerRadius x:Key="TabItem_OuterCornerRadius">3 3 0 0</CornerRadius>

<Thickness x:Key="TabItem_Margin">0 2 0 0</Thickness>

<SolidColorBrush x:Key="TabItem_OuterBorder_MouseOver" Color="#FF848484"/>

<LinearGradientBrush x:Key="TabItem_Background_MouseOver" EndPoint="0.5,1" StartPoint="0.5,0">

<GradientStop Color="#FFFFFBA3" Offset="1"/>

<GradientStop Color="#FFFFFBDA"/>

</LinearGradientBrush>

<SolidColorBrush x:Key="TabItem_InnerBorder_MouseOver" Color="#FFFFFFFF"/>

<SolidColorBrush x:Key="TabItem_OuterBorder_Selected" Color="#FF848484"/>

<LinearGradientBrush x:Key="TabItem_Background_Selected" EndPoint="0.5,1" StartPoint="0.5,0">

<GradientStop Color="White"/>

<GradientStop Color="#FFFAFAFA" Offset="1"/>

</LinearGradientBrush>

<SolidColorBrush x:Key="TabItem_InnerBorder_Selected" Color="#FFFFFFFF"/>

<Thickness x:Key="TabItem_Margin_Selected">0</Thickness>

<SolidColorBrush x:Key="TabItem_OuterBorder_SelectedMouseOver" Color="#FFFFC92B"/>
