Question

When I select a tab from my TabControl in WPF I get a dotted outline or border or w/e you wanna call it around the header:

My question is: is there an option for this to not show, because it’s kind of annoying. When the whole window isn’t active this outline doesn’t show, and still I would like to have it removed when the window’s active.

And I’m sorry for the stupid question but I just couldn’t think of what exactly to search in Google.

FocusVisualStyle is what you looking for, set this property to null for TabItems in common style-

    <TabControl>
        <TabItem Header="Page1"/>
        <TabItem Header="Page2"/>
        <TabItem Header="Page3"/>
        <TabControl.ItemContainerStyle>
            <Style TargetType="TabItem">
                <Setter Property="FocusVisualStyle" Value="{x:Null}"/>
            </Style>
        </TabControl.ItemContainerStyle>
    </TabControl>
