Solution

Set the `HorizontalContentAlignment` of the `ItemContainerStyle`:

<ListView ItemsSource="{Binding}">
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
        </Style>
    </ListView.ItemContainerStyle>
</ListView>

Result:

Problem

I'm looking to set the background of a column in a WPF GridView. Many Google results have pointed towards setting the GridViewColumn.CellTemplate to change the appearance of a column. However, I'm met with an issue when setting the background color; it's not stretching to fill the cell: Here's the xaml I'm working with: ``` <Window x:Class="ScratchPadWpf.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Width="300" Height="300"> <Grid> <ListView ItemsSource="{Binding}"> <ListView.View> <GridView> <GridViewColumn> <GridViewColumn.CellTemplate> <DataTemplate> <Grid Background="Red"> <TextBlock Text="{Binding FirstName}"/> </Grid> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <GridViewColumn> <GridViewColumn.CellTemplate> <DataTemplate> <Grid Background="Yellow"> <TextBlock Text="{Binding LastName}"/> </Grid> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> </ListView> </Grid> </Window> ``` And the xaml.cs for good measure: ``` public partial class Window1 : Window { public Window1() { InitializeComponent(); DataContext = new[] { new {FirstName = "Jim", LastName = "Bob"}, new {FirstName = "Frank", LastName = "Smith"}, new {FirstName = "Tooth", LastName = "Paste"}, }; } } ``` Setting the DataTemplate's Grid's width and height to be larger than the cell with a negative margin can produce a close result, but if you resize the column, the problem shows itself again. ``` <Grid Background="Yellow" Height="22" Width="50" Margin="-6"> ``` Is there a way to fill the cell with color?
