How to remove gap between ListViewItems in Win7

Question

I developed a WPF application under WinXP and my ListView had my expected layout. After starting the same software under Win7, I saw that the ListViewItems have a small gap between each row. I played with Margin und Padding for each element, but I can’t find a solution where the layout is the same under WinXP and Win7 without writing individual code.
I assume that it has something to do with the current Windows theme, but I can’t catch it. Does some have a hint?

Here is some (simplified) XAML that I use

<ListView x:Name="ListView">
    <ListView.Resources>
        <Style x:Key="CellBorderStyle" TargetType="{x:Type Border}">
            <Setter Property="BorderThickness" Value="0,0,1,1"></Setter>
            <Setter Property="BorderBrush" Value="LightGray"></Setter>
            <Setter Property="Margin" Value="-6,0,-6,0"></Setter>
        </Style>
        <DataTemplate x:Key="NameTemplate">
            <Border Name="NameBorder" Style="{StaticResource CellBorderStyle}">
                <TextBlock>MyName</TextBlock>
            </Border>
        </DataTemplate>
        <DataTemplate x:Key="AddressTemplate">
            <Border Name="AddressBorder" Style="{StaticResource CellBorderStyle}" Background="LightSteelBlue">
                <TextBlock>MyAddress</TextBlock>
            </Border>
        </DataTemplate>
        <DataTemplate x:Key="StreetTemplate">
            <Border Name="StreetBorder" Style="{StaticResource CellBorderStyle}" Background="LightGreen">
                <TextBlock>MyStreet</TextBlock>
            </Border>
        </DataTemplate>
        <DataTemplate x:Key="CityTemplate">
            <Border Name="CityBorder" Style="{StaticResource CellBorderStyle}">
                <TextBlock>MyCity</TextBlock>
            </Border>
        </DataTemplate>
    </ListView.Resources>
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <Setter Property="HorizontalContentAlignment" Value="Stretch"></Setter>
            <Setter Property="VerticalContentAlignment" Value="Stretch"></Setter>
        </Style>
    </ListView.ItemContainerStyle>
    <ListView.View>
        <GridView>
            <GridView.Columns>
                <GridViewColumn Header="Name" x:Name="colName"
                            CellTemplate="{StaticResource NameTemplate}"></GridViewColumn>
                <GridViewColumn Header="Address" x:Name="colAddress" 
                            CellTemplate="{StaticResource AddressTemplate}"></GridViewColumn>
                <GridViewColumn Header="Street" x:Name="colStreet" 
                            CellTemplate="{StaticResource StreetTemplate}"></GridViewColumn>
                <GridViewColumn Header="City" x:Name="colCity" 
                            CellTemplate="{StaticResource CityTemplate}"></GridViewColumn>
            </GridView.Columns>
        </GridView>
    </ListView.View>
</ListView>

Answer 1

You have to change the border top and bottom margins as well:

enter code here
        <Setter Property="Margin" Value="-6,0,-6,0"></Setter>
to:
        <Setter Property="Margin" Value="-6,-3,-6,-3"></Setter>

Extracted ControlTemplate using Expression Blend. Modified BorderThickness in Style of ListViewItem to 0.

<UserControl.Resources>
    <Style x:Key="ListViewItemFocusVisual">
        <Setter Property="Control.Template">
            <Setter.Value>
                <ControlTemplate>
                    <Rectangle RadiusY="2" RadiusX="2" Stroke="#8E6EA6F5" StrokeThickness="1"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
    <LinearGradientBrush x:Key="ListItemHoverFill" EndPoint="0,1" StartPoint="0,0">
        <GradientStop Color="#FFF1FBFF" Offset="0"/>
        <GradientStop Color="#FFD5F1FE" Offset="1"/>
    </LinearGradientBrush>
    <LinearGradientBrush x:Key="ListItemSelectedFill" EndPoint="0,1" StartPoint="0,0">
        <GradientStop Color="#FFD9F4FF" Offset="0"/>

The extra space if putting focus on the listview.

It goes away when you use

<Setter Property="Focusable" Value="false"/>

On the itemcontainerstyle
