WPF GridViewColumn对齐不起作用

Question

我希望GridViewColumn"from"中的信息与右边对齐.

这就是我所做的,它不起作用:

    <ListView ItemsSource="{Binding VolumeNumber}" HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch" >
       <ListView.View>
          <GridView AllowsColumnReorder="False">
             <GridViewColumn Header="SomeStatus" DisplayMemberBinding="{Binding Name}" Width="170" />
             <GridViewColumn Header="from" DisplayMemberBinding="{Binding Value, StringFormat=0.000000}" Width="170 >
                <GridViewColumn.CellTemplate>
                   <DataTemplate>
                      <TextBlock TextAlignment="Right" Width="40"/>
                   </DataTemplate>
                </GridViewColumn.CellTemplate>
             </GridViewColumn>
          </GridView>
       </ListView.View>
    </ListView>

如果您只想将一个特定列对齐到右侧,请尝试使用示例

这是我的实施

<Window.Resources>
    <Style TargetType="ListViewItem">
        <Setter Property="HorizontalContentAlignment" Value="Stretch" />
    </Style>
</Window.Resources>
<Grid>
    <ListView ItemsSource="{Binding VolumeNumber}">
        <ListView.View>
            <GridView>
                <GridViewColumn Header="SomeStatus" DisplayMemberBinding="{Binding Name}" Width="170"/>
                <GridViewColumn Header="from" Width="170">
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Value}" TextAlignment="Right" />
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>
            </GridView>
        </ListView.View>
    </ListView>
</Grid>
</Window>

现在不要在GridViewColumn声明中设置DisplayMemberBinding ="{Binding Value}",你需要在textblock中设置它! 否则它将忽略您的celltemplate

要更改列的对齐方式,需要指定每个ListViewItem的Horizo​​ntalContentAlignment属性为Stretch,以便每个ListViewItem中的元素可以跨越或沿每列的整个宽度定位.由于ListView绑定到数据源,因此需要创建一个设置Horizo​​ntalContentAlignment的样式.接下来,您需要使用DataTemplate来显示内容,而不是使用DisplayMemberBinding属性.要显示每个模板的值,DataTemplate只能包含将其Horizo​​ntalAlignment属性设置为Right的TextBlock.以下示例定义使列右对齐所需的样式和DataTemplate,并更改GridViewColumn以引用DataTemplate.

这里的问题是ListViewItem（即每个GridViewColumn单元格的容器）。您必须将其属性设置HorizontalContentAlignment为Stretch.

看看这里（DisplayMemberBinding如果要使用 DataTemplate，还需要删除）：

<ListView ItemsSource="{Binding VolumeNumber}" HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch" >
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <Setter Property="HorizontalContentAlignment" Value="Stretch" />
        </Style>
    </ListView.ItemContainerStyle>
    <ListView.View>
        <GridView AllowsColumnReorder="False">
            <GridViewColumn Header="SomeStatus" DisplayMemberBinding="{Binding Name}" Width="170" />
            <GridViewColumn Header="from" Width="170">
            <GridViewColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Value, StringFormat=0.000000}" TextAlignment="Right" />
                </DataTemplate>
            </GridViewColumn.CellTemplate>
            </GridViewColumn>
        </GridView>
    </ListView.View>
</ListView>
