                                SelectionMode="Multiple" Width="573" Height="123" VerticalAlignment="Bottom" Margin="0,0,0,-27">

                                                <ControlTemplate TargetType="{x:Type ListBoxItem}">
                                                    <CheckBox Margin="5,2"
                                          IsChecked="{Binding IsSelected, RelativeSource={RelativeSource TemplatedParent}}">
                                                        <ContentPresenter />
                                                    </CheckBox>
                                                </ControlTemplate>
                                            </Setter.Value>
                                        </Setter>
                                    </Style>
                                </ListBox.Resources>
                            </ListBox>
                        </DockPanel>
                    </UniformGrid>
                </TabItem>
</TabControl>

And inside <TabControl> I have my red line code

 <!--red line on up of the app -->
            <Grid x:Name="redGrid" Height="13" HorizontalAlignment="Left" VerticalAlignment="Top" Width="573" Background="#b20837" MouseDown="redGrid_MouseDown" Margin="230,0,0,0"/>
