使用ScrollViewer滚动WebView

Question

我希望能够使用ScrollViewer一次滚动我的内容，所以我有一个带有两个控件的Grid;一个Button和一个包含WebView的网格。

当我滚动浏览WebView时，标题是否也被隐藏（向上滚动）？

我的代码在下面

<ScrollViewer Grid.Row="1" VerticalScrollBarVisibility="Auto" VerticalScrollMode="Auto" IsScrollInertiaEnabled="True" x:Name="ContentScroll">
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="Auto" />
                    <RowDefinition Height="*" />
                    <RowDefinition Height="Auto" />
                </Grid.RowDefinitions>


                <Button Grid.Row="0" VerticalAlignment="Stretch" HorizontalAlignment="Left" Style="{StaticResource CustomButton}" Foreground="{Binding ElementName=Page, Path=Theme.PrimaryForeground, FallbackValue='#000000'}">
                    <Button.Content>
                        <TextBlock Margin="10,5,3,0" TextWrapping="WrapWholeWords" Text="{Binding ElementName=Page, Path=entry.Title}" FontSize="{ThemeResource TextStyleLargeFontSize}" FontWeight="Normal" x:Name="tittle" />
                    </Button.Content>
                </Button>

                    <Grid Margin="0" Grid.Row="1">
                        <WebView x:Name="content" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
                </Grid>

            </Grid>
        </ScrollViewer>

任何人都有任何提示吗？
