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

这是一个代码:

<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>
                                                <RowDefinition Height="auto" />
                                                <RowDefinition Height="auto" />
                                            </Grid.RowDefinitions>
                                            <TextBlock Text="{Binding Name}" Grid.Column="0" />
                                            <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>
                                    </DataTemplate>
                                </GridView.ItemTemplate>
                            </GridView>
                        </Grid>
                    </DataTemplate>
                </GridView.ItemTemplate>
            </GridView>

推荐答案

默认情况下，GridView 使用

虽然您已经将 Horizo​​ntalContentAlignment 或 Horizo​​ntalAlignment 设置为 Stretch for GridViewItem，但是 的大小>GridViewItem 受限于 ItemsWrapGrid.

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

ItemsWrapGrid 在显示多个项目的 ItemsControl 中从左到右或从上到下按顺序定位子元素.当元素超出容器边缘时，元素将定位在下一行或下一列.

因此在 ItemsWrapGrid 中，项目不会被拉伸.

So in ItemsWrapGrid, items won't be stretched.

如果你想水平拉伸 GridViewItem，我们可以使用 ItemsStackPanel 而不是 ItemsWrapGrid，如下所示:

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

在Resources中，添加一个ItemsPanelTemplate和ItemsStackPanel:

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

然后在GridView中使用这个模板:

Then use this template in GridView:

<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 而不是 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.
