                </ListView.View>
            </ListView>

Thank you for your help. I tried several things but no good result.

You can define an ItemContainerStyle that would set your tooltip template and content.

See an example below, here I define an UniformGrid to display multiple text lines in one column. You are free to setup your tooltip as you wish. You still need to tell the view which data properties need to be displayed in the tooltip.

<ListView ItemsSource="{Binding Articulos}">
  <ListView.ItemContainerStyle>
    <Style TargetType="{x:Type ListViewItem}">
      <Setter Property="ToolTip">
        <Setter.Value>
          <UniformGrid Columns="1">
            <TextBlock Text="{Binding CodigoDeBarras}"/>
            <TextBlock Text="{Binding Descripcion}"/>
            <TextBlock Text="{Binding AnyOtherProperty}"/>
          </UniformGrid>
        </Setter.Value>
      </Setter>
    </Style>
  </ListView.ItemContainerStyle>
</ListView>
