WPF tab control spacing between headers

Question

The default behavior of the WPF Tabcontrol is to place the Tab Headers adjacent to each other, without any empty space in between. What if I wanted to specify a gap between the headers? Do I have to define a control template for this? I'm relatively new to WFP and any help is appreciated.

Thanks

I believe you will need to define a custom control template for the TabItem, maybe even one for the TabControl. Here is an example of a TabItem that uses a spacer for some separation.

<Style
    x:Key="SpacedTab"
    TargetType="{x:Type TabItem}">
    <Setter
        Property="Template">
        <Setter.Value>
            <ControlTemplate
                TargetType="{x:Type TabItem}">
                <Border
                    x:Name="Spacer"
                    Width="Auto"
                    Height="Auto"
                    Padding="0 0 5 0"
                    Margin="0 0 0 0"
                    BorderBrush="Transparent"
                    BorderThickness="0">
                    <Border
                        x:Name="Border"
                        MinWidth="150"
                        Width="Auto"
                        Height="30"
                        Background="Gray"
                        BorderBrush="DarkGray"
                        BorderThickness="0,0,0,0"
                        CornerRadius="6,6,0,0"
                        Cursor="Hand"
                        VerticalAlignment="Bottom">
                        <ContentPresenter
                            x:Name="ContentSite"
                            TextElement.FontSize="10pt"
                            TextElement.FontFamily="Arial"
                            TextElement.Foreground="Black"
                            VerticalAlignment="Center"
                            HorizontalAlignment="Center"
                            ContentSource="Header"
                            Margin="8,3,8,3"
                            Width="Auto"
                            Height="Auto" />
                    </Border>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Hopefully that is a nudge in the right direction; you will still need to add that as a style resource and reference it from your TabControl -> TabItem.
