我想水平拉伸(stretch) ListView 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 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, 0"/>
</Grid>
</DataTemplate>
</GroupStyle.HeaderTemplate>

最佳答案

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>
