WPF TabControl XP Styling Problem

Answer 1

Found a solution, normal method - pull a simple styled control in blend apart :)

Here's the style I had to add to remove that border in case anyone is interested:

<Style TargetType="{x:Type TabControl}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type TabControl}">
                    <Grid KeyboardNavigation.TabNavigation="Local">
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="33"/>
                            <ColumnDefinition Width="*"/>
                        </Grid.ColumnDefinitions>
                        <TabPanel Grid.Column="0" Margin="0,0,4,-1" x:Name="HeaderPanel" Background="Transparent" IsItemsHost="True" Panel.ZIndex="1" KeyboardNavigation.TabIndex="1"/>
                        <Border Grid.Column="1" x:Name="Border" Background="{DynamicResource WindowBackgroundBrush}" BorderBrush="{DynamicResource SolidBorderBrush}" BorderThickness="0" CornerRadius="2" KeyboardNavigation.DirectionalNavigation="Contained" KeyboardNavigation.TabNavigation="Local" KeyboardNavigation.TabIndex="2">
                            <ContentPresenter Margin="4" x:Name="PART_SelectedContentHost" ContentSource="SelectedContent"/>
                        </Border>
                    </Grid>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsEnabled" Value="False">
                            <Setter Property="Foreground" Value="{DynamicResource DisabledForegroundBrush}"/>
                            <Setter Property="BorderBrush" Value="{DynamicResource DisabledBorderBrush}" TargetName="Border"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
