windows商店应用程序中的TextTrimming in ContentPresenter

Question

我在windows商店应用程序中编辑了ListBoxItem的样式。当条目的内容很长时，我想修剪它，就像textblock中一样，我们有属性TextTrimming = "CharacterEllipsis“。我试过两种方法。

<ContentPresenter x:Name="ContentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" ContentTransitions="{TemplateBinding ContentTransitions}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}">
    <TextBlock TextTrimming="WordEllipsis" Text="{TemplateBinding Content}"        Margin="{TemplateBinding Padding}"/>
</ContentPresenter>

和

<ContentPresenter x:Name="ContentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" ContentTransitions="{TemplateBinding ContentTransitions}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}">
  <ContentPresenter.Resources>
    <Style TargetType="TextBlock">
      <Setter Property="TextTrimming" Value="CharacterEllipsis"/>
      <Setter Property="MaxWidth" Value="10"/>
      <Setter Property="Foreground" Value="Red"/>
    </Style>
  </ContentPresenter.Resources>
</ContentPresenter>

但不为我工作，任何帮助都会感激的。

Answer 1

首先，在XAML中设置ListBox属性ScrollViewer.HorizontalScrollBarVisibility="Disabled"。

然后使用您的第一个XAML示例，删除包装ContentPresenter的TextBlock (在本场景中不需要它)，并替换为<Grid>

Answer 2

通过编辑ContentTemplate完成，

<ContentPresenter x:Name="ContentPresenter" ContentTransitions="{TemplateBinding ContentTransitions}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}">
      <ContentPresenter.ContentTemplate>
        <DataTemplate>
         <TextBlock Text="{Binding ElementName=ContentPresenter, Path=Content}" TextTrimming="CharacterEllipsis"/>
        </DataTemplate>
       </ContentPresenter.ContentTemplate>
</ContentPresenter>
