我的应用程序的屏幕截图

我想水平拉伸列表视图的项目，以便绿色区域（选定的 ItemContainer）从 groupheader 到达右侧。

我尝试将我能想到的每个元素都设置为“Horizo​​ntalAlignment="Stretch"”，但没有任何效果。

这是我的列表视图

我找到了解决方案！

我必须将 GroupStyle.ContainerStyle 中的 GroupItemTemplate 更改为 Grid

<GroupStyle.ContainerStyle>
<Style TargetType="GroupItem">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="GroupItem" >
                <Grid>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="auto" />
                        <ColumnDefinition Width="*" />
                    </Grid.ColumnDefinitions>
                    <ContentPresenter Content="{TemplateBinding Content}" />
                    <ItemsControl Grid.Column="1" x:Name="ItemsControl" ItemsSource="{Binding GroupItems}"/>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

这是标题所需要的：

<GroupStyle.HeaderContainerStyle>
    <Style TargetType="ListViewHeaderItem">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="ListViewHeaderItem">
                    <ContentPresenter Content="{TemplateBinding Content}" HorizontalAlignment="Stretch"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</GroupStyle.HeaderContainerStyle>

在您的ItemContainerStyle（AppointmentListView）上将HorizontalContentAlignment属性设置为Stretch

基于 Alexandre Zollinger Chohfi 的回答，一个更简洁的版本：

<GroupStyle.HeaderContainerStyle>
    <Style TargetType="ListViewHeaderItem">
        <Setter Property="HorizontalContentAlignment"
                Value="Stretch" />
    </Style>
</GroupStyle.HeaderContainerStyle>
