WPF ListView控件右边框切断

Question

我试图创建一个3个文本行WPF列表视图，但右边框设置不正确（由围绕1-3像素 right border切断。左手边是罚款。

<Window x:Class="ListViewBorder.MainWindow" 
    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" 
    xmlns:local="clr-namespace:ListViewBorder" 
    mc:Ignorable="d" 
    x:Name="MainWindowUc" 
    Title="MainWindow" Height="800" Width="1024"> 
<Grid> 
    <ListView 
     ItemsSource="{Binding ElementName=MainWindowUc, Path=Items}" 
     BorderBrush="DarkCyan" 
     BorderThickness="1" ScrollViewer.VerticalScrollBarVisibility="Disabled" ScrollViewer.HorizontalScrollBarVisibility="Disabled" 
     > 
     <ListView.ItemTemplate> 
      <DataTemplate> 
       <Border Background="DarkGray" 
         BorderBrush="Blue" 
         BorderThickness="2" 
         CornerRadius="6" 
         ScrollViewer.VerticalScrollBarVisibility="Disabled" 
         Width="{Binding (FrameworkElement.ActualWidth), RelativeSource={RelativeSource AncestorType=ScrollContentPresenter}}"> 
        <WrapPanel Width="{Binding (FrameworkElement.ActualWidth), RelativeSource={RelativeSource AncestorType=Border}}" 
           > 

         <TextBlock Padding="1" Text="{Binding Column1}" Width="{Binding (FrameworkElement.ActualWidth), RelativeSource={RelativeSource AncestorType=WrapPanel}}" TextWrapping="NoWrap"></TextBlock> 
         <TextBlock Padding="1" Text="{Binding Column2}" Width="{Binding (FrameworkElement.ActualWidth), RelativeSource={RelativeSource AncestorType=WrapPanel}}" TextWrapping="Wrap"></TextBlock> 
         <TextBlock Padding="1" Text="{Binding Column3}" Width="{Binding (FrameworkElement.ActualWidth), RelativeSource={RelativeSource AncestorType=WrapPanel}}" TextWrapping="Wrap" TextAlignment="Right"></TextBlock> 

        </WrapPanel> 

       </Border> 
      </DataTemplate> 
     </ListView.ItemTemplate> 
    </ListView> 
</Grid> 

如何“修理”这个

Answer 1

您不必在任何地方设置宽度明确，只是删除您的宽度绑定，试试这个：

<ListView BorderBrush="DarkCyan" 
     BorderThickness="1" 
     ItemsSource="{Binding ElementName=MainWindowUc, Path=Items}" 
     HorizontalContentAlignment="Stretch" 
     ScrollViewer.HorizontalScrollBarVisibility="Disabled" 
     ScrollViewer.VerticalScrollBarVisibility="Disabled"> 
<ListView.ItemTemplate> 
    <DataTemplate> 
     <Border Background="DarkGray" 
       BorderBrush="Blue" 
       BorderThickness="2" 
       CornerRadius="6" 
       Padding="6" 
       ScrollViewer.VerticalScrollBarVisibility="Disabled"> 
      <StackPanel> 
       <TextBlock Padding="1" 
          Text="{Binding Column1}" 
          TextWrapping="NoWrap" /> 
       <TextBlock Padding="1" 
          Text="{Binding Column2}" 
          TextWrapping="Wrap" /> 
       <TextBlock Padding="1" 
          Text="{Binding Column3}" 
          TextAlignment="Right" 
          TextWrapping="Wrap" /> 

      </StackPanel> 
     </Border> 
    </DataTemplate> 
</ListView.ItemTemplate> 

的关键是以下几点：HorizontalContentAlignment="Stretch"

这看起来是这样的：
