水平拉伸分组ListView的项目
我想水平拉伸listview的项目，以便绿色区域（选定的ItemContainer）从groupheader到达右边。
我试图将我能想到的每个元素设置为“HorizontalAlignment =”Stretch“”，但没有任何效果。
这是我的ListView
<ListView
HorizontalAlignment="Stretch"

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>
答案 1 :(得分：4)
这是标题所需的内容：
<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>
答案 2 :(得分：1)
在ItemContainerStyle（ AppointmentListView ）上，将HorizontalContentAlignment属性设置为Stretch
答案 3 :(得分：0)
基于Alexandre Zollinger Chohfi的回答，一个更为简洁的版本：
<GroupStyle.HeaderContainerStyle>
<Style TargetType="ListViewHeaderItem">
<Setter Property="HorizontalContentAlignment"
Value="Stretch" />
</Style>
</GroupStyle.HeaderContainerStyle>
