如何水平拉伸GridViewItem？尝试在 ItemContainerStyle 中设置属性 Horizo​​ntalContentAlignment 或样式属性。这无济于事。

How to stretch GridViewItem horizontaly? Trying to set property HorizontalContentAlignment or style property in ItemContainerStyle. This does not help.

这里是代码：

<GridView ItemsSource="{x:Bind Banks}" SelectionMode="None" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch">
                <GridView.ItemContainerStyle>
                    <Style TargetType="GridViewItem">
                        <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
                    </Style>
                </GridView.ItemContainerStyle>
                <GridView.ItemTemplate>
                    <DataTemplate x:DataType="model:Bank">
                        <Grid HorizontalAlignment="Stretch">
                            <Grid.RowDefinitions>
                                <RowDefinition Height="auto" />
                                <RowDefinition Height="auto" />
                            </Grid.RowDefinitions>
                            <TextBlock Text="{Binding Name}" Grid.Column="0" />

                            <GridView ItemsSource="{x:Bind Departments}" Grid.Row="1" HorizontalContentAlignment="Stretch" IsItemClickEnabled="True" VerticalContentAlignment="Stretch">
                                <GridView.ItemContainerStyle>
                                    <Style TargetType="GridViewItem">
                                        <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
                                    </Style>
                                </GridView.ItemContainerStyle>
                                <GridView.ItemTemplate>
                                    <DataTemplate x:DataType="model:Department">
                                        <Grid HorizontalAlignment="Stretch">
                                            <Grid.ColumnDefinitions>
                                                <ColumnDefinition Width="250" />
                                                <ColumnDefinition Width="*" />
                                                <ColumnDefinition Width="40" />
                                            </Grid.ColumnDefinitions>
                                            <Grid.RowDefinitions>

                                            <TextBlock Text="{Binding Address}" Grid.Column="0" Grid.Row="1" />

                                            <TextBlock Text="{Binding USD.Date}" Grid.Column="1" Grid.RowSpan="2"/>

                                            <TextBlock Text="{Binding USD.Sell}" Grid.Column="2" />
                                            <TextBlock Text="{Binding USD.Buy}" Grid.Column="2" Grid.Row="1"/>
                                        </Grid>

                                </GridView.ItemTemplate>
                            </GridView>
                        </Grid>
                    </DataTemplate>
                </GridView.ItemTemplate>
            </GridView>

推荐答案

默认情况下， GridView 使用

尽管您已设置 Horizo​​ntalContentAlignment 或 Horizo​​ntalAlignment 到 Stretch 到 GridViewItem ，但是 GridViewItem 的大小受 ItemsWrapGrid 的限制。

Although you've set HorizontalContentAlignment or HorizontalAlignment to Stretch for GridViewItem, but the size of GridViewItem is limited by ItemsWrapGrid.

因此在 ItemsWrapGrid 中，项目不会被拉伸。

So in ItemsWrapGrid, items won't be stretched.

如果要水平拉伸 GridViewItem ，我们可以使用 ItemsStackPanel 而不是像 ItemsWrapGrid 那样：

If you want to stretch GridViewItem horizontaly, we can use ItemsStackPanel instead of ItemsWrapGrid like following:

在资源中，添加 ItemsPanelTemplate 和 ItemsStackPanel ：

<Page.Resources>
    <ItemsPanelTemplate x:Key="MyItemsPanelTemplate">
        <ItemsStackPanel />
    </ItemsPanelTemplate>
</Page.Resources>

然后在 GridView 中使用此模板：

<GridView HorizontalContentAlignment="Stretch"
          VerticalContentAlignment="Stretch"
          ItemsPanel="{StaticResource MyItemsPanelTemplate}"
          ItemsSource="{x:Bind Banks}"
          SelectionMode="None">
    ...
        <GridView Grid.Row="1"
              HorizontalContentAlignment="Stretch"
              VerticalContentAlignment="Stretch"
              IsItemClickEnabled="True"
              ItemsPanel="{StaticResource MyItemsPanelTemplate}"
              ItemsSource="{x:Bind Departments}">
        ...
        </GridView>
    ...
</GridView>

或者我们可以使用 ListView 代替 GridView 作为 ListView 的默认 ItemsPanel 是 ItemsStackPanel 。

Or we can use ListView instead of GridView as ListView's default ItemsPanel is ItemsStackPanel.
