导读：我不知道为什么这段代码工作正常： ScrollViewer Height="674" HorizontalAlignment="Left" VerticalAlignment="Top" Width="480" Margin="0,94,0" HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden" StackPanel Button Content

我不知道为什么这段代码工作正常：

<ScrollViewer Height="674" HorizontalAlignment="Left" VerticalAlignment="Top" Width="480" Margin="0,94,0" HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden">
    <StackPanel>
        <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
        <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
        <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
        <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
        <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
        <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
        <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
        <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
        <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
        <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
        <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
        <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
        <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
        <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
        <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
    </StackPanel>
</ScrollViewer>

这不是：

<ScrollViewer Height="674" HorizontalAlignment="Left" VerticalAlignment="Top" Width="480" Margin="0,0" HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden">
    <ListBox Width="480" ItemsSource="{Binding ViewModel_ObservableCollection_Property_With_15_Items}">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <Grid Height="85">
                    <Button Content="custom control" VerticalAlignment="Center" Width="480" Height="70" />
                </Grid>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>
</ScrollViewer>

ListBox版本无法显示ScrollViewer中的所有项目.诀窍是什么？

解决方法

您应该避免使用ScrollViewer来包装ListBox,因为在默认的ListBox样式中已经存在ScrollViewer.
