ListView ignoring DataTemplates when using a ControlTemplate

Question

I try to implement a multi column ListView. Everything worked just fine until I tried to style the mouseover- and selection-look of the list view items. I therefore created a ControlTemplate (see XAML below). When I use the ControlTemplate, the DataTemplates for the columns are ignored. When I remove the ControlTemplate everything is fine again. Can someone point me to the error? Thanks!

<ListView.ItemContainerStyle>
<Style TargetType="{x:Type ListViewItem}">
    <Style.Resources>
        <SolidColorBrush Color="#FF355bbf" x:Key="ListItemSelectedFill" />
    </Style.Resources>
    <Setter Property="HorizontalContentAlignment" Value="Stretch"/>

    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ListViewItem}">
                <Border CornerRadius="2" SnapsToDevicePixels="True"
                        BorderThickness="{TemplateBinding BorderThickness}"
                        BorderBrush="{TemplateBinding BorderBrush}"
                        Background="{TemplateBinding Background}">
                    <Border x:Name="InnerBorder" CornerRadius="1" BorderThickness="1">
                        <Grid>
                            <Grid.RowDefinitions>
                                <RowDefinition MaxHeight="11" />
                                <RowDefinition />
                            </Grid.RowDefinitions>
                            <Rectangle x:Name="UpperHighlight" Visibility="Collapsed" Fill="#75FFFFFF" />
                            <ContentPresenter Grid.Row="0"  Grid.RowSpan="2" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />

Replace the ContentPresenter in your ContentTemplate by a GridViewRowPresenter:

<ControlTemplate TargetType="{x:Type ListViewItem}">
    <Border ...>
        <Border ...>
            <Grid>
                ...
                <GridViewRowPresenter ... />
            </Grid>
        </Border>
    </Border>
</ControlTemplate>
