如何同步两个ScrollViewer？

我使用了ScrollViewer中的ViewChanged。一切对我来说都很好。这是MainPage.xaml.cs中的代码：

protected override void OnNavigatedTo(NavigationEventArgs e)
    {
        var list = new List<int>();
        for (int i = 0; i < 100; ++i)
        {
            list.Add(i);
        }

        ItemsControl1.ItemsSource = list;
        ItemsControl2.ItemsSource = list;
    }

    private void ScrollViewer1_OnViewChanged(object sender, ScrollViewerViewChangedEventArgs e)
    {
        if (ScrollViewer1.VerticalOffset != ScrollViewer2.VerticalOffset)
        {
            ScrollViewer2.ScrollToVerticalOffset(ScrollViewer1.VerticalOffset);
        }
    }

    private void ScrollViewer2_OnViewChanged(object sender, ScrollViewerViewChangedEventArgs e)
    {
        if (ScrollViewer1.VerticalOffset != ScrollViewer2.VerticalOffset)
        {
            ScrollViewer1.ScrollToVerticalOffset(ScrollViewer2.VerticalOffset);
        }
    }

还有MainPage.xaml的XAML代码

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="50"/>
        <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>
    <ScrollViewer Grid.Column="0"
                  x:Name="ScrollViewer1"
                  ViewChanged="ScrollViewer1_OnViewChanged">
        <ItemsControl x:Name="ItemsControl1">
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding}"/>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
    </ScrollViewer>
    <ScrollViewer Grid.Column="2"
                  x:Name="ScrollViewer2"
                  ViewChanged="ScrollViewer2_OnViewChanged">
        <ItemsControl x:Name="ItemsControl2">
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding}"/>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
    </ScrollViewer>
</Grid>

试试这个，希望对您有所帮助。
