c# - Windows Phone 8 中的 ListBox 自动下一行

Question

如何在第一行被占时让图片跳到下一行？

下面是我当前的代码:

<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
    <TextBlock Text="Picture" Style="{StaticResource PhoneTextNormalStyle}"/>
    <ListBox x:Name="picList" ScrollViewer.HorizontalScrollBarVisibility="Auto">
        <ListBox.ItemsPanel>
            <ItemsPanelTemplate>
                <StackPanel Orientation="Horizontal"/>
            </ItemsPanelTemplate>
        </ListBox.ItemsPanel>
        <ListBox.ItemTemplate>
            <DataTemplate>
                <StackPanel>
                    <Image Source="{Binding Picture}" Height="80" Width="80"/>
                </StackPanel>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>
</Grid>

使用 WrapPanel 而不是 StackPanel。由于 Windows Phone 8 不提供 WrapPanel 控件，您需要使用 Windows Phone Toolkit .

<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
    <TextBlock Text="Picture" Style="{StaticResource PhoneTextNormalStyle}"/>
    <ListBox x:Name="picList" ScrollViewer.HorizontalScrollBarVisibility="Auto">
        <ListBox.ItemsPanel>
            <ItemsPanelTemplate>
                <WrapPanel Orientation="Horizontal"
                           Width="300"
                           HorizontalAlignment="Left"
                           />
            </ItemsPanelTemplate>
        </ListBox.ItemsPanel>
        <ListBox.ItemTemplate>
            <DataTemplate>
                <StackPanel>
                    <Image Source="{Binding Picture}" Height="80" Width="80"/>
                </StackPanel>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>
</Grid>
