WPF Set ListViewItem.Background with binding

I have a ListView in grid mode in which I am displaying a list of data. The grid works, but I can't bind the Background property. If "FileExists == false" then I want to display the line in red. Why doesn't it work?

The list is loaded into Windows.Loaded. I also added the [ImplementPropertyChanged] attribute to the data class (using NuGet PropertyChanged.Fody), but that didn't help.

<ListView x:Name="VideosView" TabIndex="2" SelectedValuePath="VideoId" Margin="10,50,10,37" ButtonBase.Click="VideosView_ColumnHeaderClick">
    <ListView.Resources>
        <Style TargetType="{x:Type ListViewItem}">
            <Style.Triggers>
                <DataTrigger Binding="{Binding FileExists}" Value="False">
                    <Setter Property="Background" Value="Red" />
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </ListView.Resources>
    <ListView.View>
        <GridView>
            <GridViewColumn DisplayMemberBinding="{Binding Artist, Mode=OneWay}" Header="Artist" Width="100"/>
            <GridViewColumn DisplayMemberBinding="{Binding Title, Mode=OneWay}" Header="Title" Width="300"/>
            <GridViewColumn DisplayMemberBinding="{Binding Length, Converter={StaticResource TimeSpanConverter}, Mode=OneWay}" Header="Length" Width="40"/>
        </GridView>
    </ListView.View>
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <EventSetter Event="Control.MouseDoubleClick" Handler="VideosView_ItemDoubleClick"/>
        </Style>
    </ListView.ItemContainerStyle>
</ListView>

      

        
        
        
      

    

Data class

[ImplementPropertyChanged]
public class VideoListItem {
    public VideoListItem() {
    }

    public int VideoId { get; set; }
    public string Artist { get; set; }
    public string Title { get; set; }
    public string FileName { get; set; }
    public int? Length { get; set; }
    public bool FileExists { get; set; }
    public bool IsInDatabase { get; set; }
}
