Question

我无法使用左对齐或居中对齐的列绘制列表视图。我已经看过了我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all columns，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，但是所有内容都是左对齐的（我已经将右对齐来测试代码）。有人能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>

Answer 1

您的ListViewItem默认情况下不会展开内容，这就是为什么所有项目都显示在左侧。添加它，它将起作用：

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

Answer 2

虽然LPL的提示已经节省了数千个令人头疼的问题，但我会更进一步，将 HorizontalContentAlignment 和 VerticalContentAlignment 定义为延伸为了在大多数使用的表驱动控件上定位预期的对齐行为：

ListView列标题和项目模板

DataGrid列标题和单元格模板。

Rembember：您可以随时define your default styles and other resources at application level，这样您就不必为每个视图定义它。

希望它能帮助像LPL这样的其他人提示帮助我。
