我无法绘制具有左对齐或居中对齐的列的列表视图。我查看了在这里或其他论坛上找到的一些解决方案，但它们似乎适用于所有专栏，或者我无法让它们正常工作。

到目前为止，我得到的最好的是这段代码，但所有内容都是左对齐的（我已将右对齐放入以测试代码）。有人可以告诉我哪里出错了吗？

<ListView Name="lsvQuestions" DockPanel.Dock="Bottom">                
     <ListView.View>
         <GridView>
             <GridViewColumn Width="450" Header="Question Text">
                 <GridViewColumn.CellTemplate>
                     <DataTemplate>
                         <TextBlock Text="{Binding QuestionText}" TextAlignment="Left"/>
                     </DataTemplate>
                 </GridViewColumn.CellTemplate>
                 </GridViewColumn>
                 <GridViewColumn Width="200" Header="Type">
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding QuestionType}" TextAlignment="Right"/>
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                 </GridViewColumn>
                 <GridViewColumn Width="100" Header="Page Number">
                     <GridViewColumn.CellTemplate>
                         <DataTemplate>
                             <TextBlock Text="{Binding QuestionPageNumber}" TextAlignment="Center"/>
                         </DataTemplate>
                     </GridViewColumn.CellTemplate>
                 </GridViewColumn>
                 <GridViewColumn Width="100" Header="Order">
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding QuestionOrder}" TextAlignment="Center"/>
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>
            </GridView>
        </ListView.View>               
    </ListView>

默认情况下，您ListViewItem的 s 不会拉伸内容，这就是所有项目都显示在左侧的原因。添加这个，它会工作：

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

尽管LPL的提示已经避免了成千上万的麻烦，但我会更进一步，将Horizo​​ntalContentAlignment和VerticalContentAlignment定义为拉伸，以便针对大多数使用的表格驱动控件的预期对齐行为：

  • ListView 列标题和项目模板

  • DataGrid 列标题和单元格模板。

记住：您始终可以在应用程序级别定义默认样式和其他资源，因此您不必在每个视图中都定义它。

希望它可以帮助其他人，例如 LPL 的提示帮助我。
