WPF: how can I have ListViewItems fit the window width and use TextEllipsis

I'm currently working with a ListView. Its ListViewItems consist of a left-aligned TextBlock and a right-aligned Button:

The ListView in an uncomplicated state.

Now, I'd like to have my Items always display the Button and shorten the TextBlock accordingly, so they don't need to display a ScrollBar:

The ListView's intended behavior.

Unfortunately, right now that doesn't work:

The ListView's current behavior.

What can I do to make it work? Here's my example code:

<Window x:Class="JansWpfTestUmgebung.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <ListView x:Name="AllItemsList"
              HorizontalContentAlignment="Stretch"
              HorizontalAlignment="Stretch">
        <ListViewItem>
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*" />
                <ColumnDefinition Width="Auto" />
            </Grid.ColumnDefinitions>
            <TextBlock Grid.Column="0"
                       TextTrimming="CharacterEllipsis" 
                       Text="Item 1 with a very long description"/>
            <Button Grid.Column="1"
                    Content="Modify" />
        </Grid>
    </ListViewItem>
        <ListViewItem>Item 2</ListViewItem>
        <ListViewItem>Item 3</ListViewItem>
    </ListView>
</Window>

Thanks for any hints! :-)

The Most important Parts are these 

<ListView HorizontalContentAlignment="Stretch"
          ScrollViewer.HorizontalScrollBarVisibility="Disabled"/>

That way your ListViewItems will fill the space, and the disabled horizontal scroll bar will prevent them from taking up more space.

My code looks like this

<ListView HorizontalContentAlignment="Stretch"
          ScrollViewer.HorizontalScrollBarVisibility="Disabled"
          ItemsSource="{Binding MyItemSourceList}"
          Width="{Binding ActualWidth, ElementName=SearchBox}"
          >
        <ListView.ItemTemplate>
            <DataTemplate>
                <Grid>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="Auto"/>
                    </Grid.ColumnDefinitions>
                    <TextBlock Grid.Column="0" 
                               Text="{Binding Name}" 
                               TextTrimming="CharacterEllipsis"/>
                    <TextBlock Grid.Column="1" 
                               Text="{Binding Tag}" 
                               HorizontalAlignment="Right" 
                               FontWeight="Bold" 
                               Foreground="LightGray"/>
                </Grid>
            </DataTemplate>
        </ListView.ItemTemplate>
</ListView>

You can do this by forcing a size on the button column: 

<Window
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
        mc:Ignorable="d" 
        x:Class="JansWpfTestUmgebung.MainWindow"
        d:DesignWidth="394">
    <ListView x:Name="AllItemsList"
              HorizontalContentAlignment="Stretch"
              HorizontalAlignment="Stretch" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
        <ListViewItem>
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*" />
                <ColumnDefinition Width="45" />
            </Grid.ColumnDefinitions>
            <TextBlock Grid.Column="0"
                TextTrimming="CharacterEllipsis" 
                Text="Item 1 with a very long description"/>
            <Button Grid.Column="1"
                    Content="Modify"/>
        </Grid>
    </ListViewItem>
        <ListViewItem Content="Item 2"/>
        <ListViewItem Content="Item 3"/>
    </ListView>
</Window>

The way it was, It does its best to keep the * sized column as big as possible, at the expense of the Auto sized column. But a fixed size will win out against a * sized.
