我希望在 WPF GridView 中设置列​​的背景.许多 Google 结果都指向设置 GridViewColumn.CellTemplate 以更改列的外观.但是，我在设置背景颜色时遇到了一个问题；它不会拉伸以填充单元格:

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:

这是我正在使用的 xaml:

Here's the xaml I'm working with:

<Window x:Class="ScratchPadWpf.Window1"
  xmlns="http://schemas.microsoft/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft/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>

和 xaml.cs 很好的衡量:

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"},
    };
  }
}

将 DataTemplate 的 Grid 的宽度和高度设置为大于具有负边距的单元格可以产生接近的结果，但是如果您调整列的大小，问题又会再次出现.

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">

有没有办法用颜色填充单元格?

Is there a way to fill the cell with color?

推荐答案

设置ItemContainerStyle的Horizo​​ntalContentAlignment:

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

结果:
