WPF:我如何让ListViewItems适合窗口宽度并使用TextEllipsis

标签: wpf listview scrollbar listviewitem

我目前正在使用ListView。它的ListViewItems包含一个左对齐的TextBlock和一个右对齐的Button:

The ListView in an uncomplicated state.

现在,我想让我的Items 总是显示Button并相应地缩短TextBlock,这样他们就不需要显示ScrollBar了:

The ListView's intended behavior.

不幸的是,现在这不起作用:

The ListView's current behavior.

我能做些什么才能让它发挥作用? 这是我的示例代码:

<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>

感谢任何提示! : - )

您可以通过在按钮列上强制调整大小来执行此操作:

<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>

它的方式是,它尽可能保持*大小的列尽可能大,代价是自动调整大小的列。但固定大小将胜过*大小。

最重要的部分是这些

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

这样你的ListViewItems将填充空间,禁用的水平滚动条将阻止它们占用更多空间。

我的代码看起来像这样

<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>
