将SemanticZoom内的GridView滚动到SemanticZoom外部的某个组

Question

除了SemanticZoom中的字母选择之外，我正在尝试在ZoomedOutView之外添加自定义字母选择，但我无法操纵GridView中的ZoomedInView {1}}

截至目前，两个字母视图中的ItemSource是相同的，并在代码隐藏中设置。

SemanticZoom工作正常，但我想要实现的是当点击右上角的一个字母时，它会滚动到ZoomedInView中的相应组。

有没有办法实现这个目标？

（我没有包含任何代码，因为代码本身不是主要问题，但是如果它应该被包括在内请告诉我）

最后我想出了一个解决方案。我正在提供代码，但在此之前从msdn链接下载Gridview示例。

GridView Sample

要在 ScenarioOutput1.xaml 和 ScenarioOutput1.xaml.cs 中进行更改才能看到效果。

所以让我们开始使用ScenarioOutput1.xaml代码我改变了请将它复制粘贴到项目中（来自msdn的GridView Demo），以便在理解代码时看到效果。

ScenarioOutput1.xaml

    <Page
    x:Class="ListViewSimple.ScenarioOutput1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    d:DesignHeight="300"
    d:DesignWidth="400">

    <Grid Height="300" VerticalAlignment="Top" Tapped="Grid_Tapped">
        <ScrollViewer x:Name="scroller" HorizontalScrollMode="Enabled" Width="auto" HorizontalScrollBarVisibility="Visible">
            <GridView x:Name="ItemGridView" Background="{StaticResource ApplicationPageBackgroundThemeBrush}"
            ItemTemplate="{StaticResource StoreFrontTileTemplate}"
            ItemContainerStyle="{StaticResource StoreFrontTileStyle}"
            ItemsPanel="{StaticResource StoreFrontGridItemsPanelTemplate}"
            BorderBrush="LightGray"
            VerticalAlignment="Top"
                      ScrollViewer.HorizontalScrollBarVisibility="Hidden"
            BorderThickness="1" ScrollViewer.VerticalScrollBarVisibility="Auto"
            SelectionMode="None"/>

        </ScrollViewer>
    </Grid>
</Page>

现在下一部分是cs文件。
