为listview列设置不同的对齐方式

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,但它们似乎适用于所有列,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,但是所有东西都是左对齐的(我已经把右对齐来测试代码).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

ListViewItem默认情况下,您不会展开内容,这就是为什么所有项目都显示在左侧.添加它,它将工作:

<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,但我会更进一步定义Horizo​​ntalContentAlignment和VerticalContentAlignment以进行拉伸,以便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,因此您无需在每个视图中定义它.

希望它可以帮助像LPL这样的其他人提示帮助我.
