WPF: Programatically adding ListViewItems that expand to the full width of their containing ListView

I have defined a custom ListViewItem contorl in XAML, which we'll call Item.xaml. These custom items are added to a list view using ListView.Items.Add().

How can I add these items so that they will expand horizontally to take up the entire width of their containing ListView? Currently they always remain their original width.

ChrisWue's answer seemed to work but then I noticed that if I had enough ListViewItems to cause the list to scroll horizontally, the items that were invisible before scrolling down did not stretch horizontally.

I found this MSDN thread that gives the correct approach:

<ListView Name="ListView" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
  <!-- Stretch the contents to match the columns' width: -->
  <ListView.ItemContainerStyle>
    <Style TargetType="ListViewItem">
      <Setter Property="HorizontalContentAlignment" Value="Stretch" />
    </Style>
  </ListView.ItemContainerStyle>
  ...

The ListView has a HorizontalContentAlignment you need to set to Stretch:

<ListView HorizontalContentAlignment="Stretch" ... >
