How can a ListBox fill its parent width?

Question

I have a ListBox and need that it fills the parent's width but have not found a way to do it, the ListBox has always the ListBox width and not the 100%.

Here is my XAML code:

<ListBox ItemsSource="{Binding anagSearchResults}" BorderThickness="0" Background="Gray"
     SelectedItem="{Binding selectCustomer}" 
     FontSize="14"    
     ScrollViewer.HorizontalScrollBarVisibility="Disabled">
     <ListBox.ItemContainerStyle>
           <Style TargetType="ListBoxItem">
               <Setter Property="HorizontalContentAlignment" Value="Stretch"></Setter>
           </Style>
     </ListBox.ItemContainerStyle>
     <ListBox.ItemTemplate>
         <DataTemplate>
               <Grid HorizontalAlignment="Stretch">
                   <Grid.ColumnDefinitions>
                       <ColumnDefinition Width="*"></ColumnDefinition>
                       <ColumnDefinition Width="*"></ColumnDefinition>
                       <ColumnDefinition Width="*"></ColumnDefinition>
                       <ColumnDefinition Width="*"></ColumnDefinition>
                    </Grid.ColumnDefinitions>
                    <TextBlock Grid.Column="0" Text="{Binding FirstName}"></TextBlock>
                    ....

What am I doing wrong?

This is possibly a duplicate question. I think the answer you are looking for at [How to get a ListBox ItemTemplate to stretch horizontally the full width of the ListBox?](http://stackoverflow.com/questions/838828/how-to-get-a-listbox-itemtemplate-to-stretch-horizontally-the-full-width-of-the). — Steve Konves, Oct 08 '12 at 22:17

I would check the HorizontalAlignment of the parent(s) and make sure none of them are set to left, right or centre.

Also it might be because one of the parents' width property has been set to a fixed value. – Mostafa Hadian Jun 05 '17 at 10:07

I would go with a ListView GridView.
Then for width you need to use a converter.
Change the converter in this sample to be parent width / 4
