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"
x:Name="AppointmentListView"
ItemContainerStyle="{StaticResource ListViewItemContainerStyle}"
ItemsSource="{Binding Source={StaticResource SelectedViewSource}}"
Grid.Column="1"
Grid.RowSpan="2">

<Grid Width="200">
<TextBlock Text="{Binding Converter={StaticResource DateYearStringConv},Path=Key}" Foreground="White" FontSize="20" FontWeight="Light" Margin="10,5,0"/>
</Grid>
</DataTemplate>

解决方法
我找到了解决方案！
我不得不将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>
