Try this Instead,

<TabControl x:Name="tabCtrlMain" ItemsSource="{Binding Items}" >
        <TabControl.Resources>
            <Style TargetType="TabItem">
                <Setter Property="Header" Value="{Binding FileName}" />
                <Setter Property="HeaderTemplate">
                    <Setter.Value>
                        <DataTemplate DataType="{x:Type TabItem}">
                            <Border x:Name="grid">
                                    <ContentPresenter>
                                        <ContentPresenter.Content>
                                            <TextBlock Text="{TemplateBinding Content}"/>
                                        </ContentPresenter.Content>
                                    </ContentPresenter>
                                </Border>
                        </DataTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </TabControl.Resources>
    </TabControl>
