将SemanticZoom内的GridView滚动到SemanticZoom外部的某个组
ken*_*trh 5 c# xaml microsoft-metro windows-8 semantic-zoom
我想添加自定义的字母选区外的SemanticZoom除了字母的选择ZoomedOutView,但我不能设法操纵GridView的ZoomedInView
最后我想出了一个解决方法。我给出了代码，但在此之前从 msdn 链接下载 Gridview 示例。
要查看效果的更改需要在ScenarioOutput1.xaml和ScenarioOutput1.xaml.cs中完成。
那么让我们从我更改的 ScenarioOutput1.xaml 代码开始，如果您对代码理解有困难，请将其复制粘贴到项目中（来自 msdn 的 GridView 演示）以查看效果。
场景输出1.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。

请在demo中实现一下，看看效果。可能还有其他解决方法，但希望尽快轻松地清除这些内容。如果您在理解上遇到任何困难，请告诉我:)
