我正在尝试将GridView中的所选项目（Windows Phone 8.1 C＃/ XAML应用程序）突出显示。我使用Blend提取了GridViewItemStyle，它包含以下内容：
<Border x:Name="SelectedBorder" BorderBrush="{ThemeResource ListViewItemSelectedBackgroundThemeBrush}" BorderThickness="{ThemeResource GridViewItemMultiselectBorderThickness}" IsHitTestVisible="False" Opacity="0">
<Grid x:Name="SelectedCheckMark" HorizontalAlignment="Right" Height="34" Opacity="0" VerticalAlignment="Top" Width="34">
<Path x:Name="SelectedEarmark" Data="M0,0 L40,0 L40,40 z" Fill="{ThemeResource ListViewItemSelectedBackgroundThemeBrush}" Stretch="Fill"/>
<Path x:Name="SelectedGlyph" Data="M0,123 L39,93 L124,164 L256,18 L295,49 L124,240 z" Fill="{ThemeResource ListViewItemCheckThemeBrush}" FlowDirection="LeftToRight" HorizontalAlignment="Right" Height="14.5" Margin="0,1,1,0" Stretch="Fill" VerticalAlignment="Top" Width="17"/>
</Grid>
</Border>
我已经定义了这个XAML使用的画笔颜色，并暂时将不透明度设置为1，以便我可以检查它应该显示。到目前为止，非常好。
在同一样式定义中还有一个可视状态组：
<VisualStateGroup x:Name="SelectionStates">
<VisualState x:Name="Unselected"/>
<VisualState x:Name="Selected">
<Storyboard>
<DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="CheckGlyph"/>
<DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="SelectedCheckMark"/>
</Storyboard>
</VisualState>
<VisualState x:Name="SelectedUnfocused">
<Storyboard>
<DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="CheckGlyph"/>
<DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="SelectedCheckMark"/>
</Storyboard>
</VisualState>
</VisualStateGroup>
但是当选择一个项目时，它不会获得视觉指示。显示指标的XAML显然正在工作，所以我试图理解为什么视觉状态组不是，特别是因为它直接来自Blend。
GridView定义如下：
<GridView
AutomationProperties.AutomationId="ItemListViewSection2"
AutomationProperties.Name="Items In Group"
SelectionMode="Single"
IsItemClickEnabled="True"
ItemsSource="{Binding GroupMembers}"
ItemTemplate="{StaticResource Individual80ItemTemplate}"
ItemContainerStyle="{StaticResource GridViewItemStyle1}"
ItemClick="ItemView_ItemClick"
ContinuumNavigationTransitionInfo.ExitElementContainer="True"
SelectionChanged="itemView_SelectionChanged"
Loaded="itemGridView_Loaded"/>
更新：如果我将SelectionMode从Single更改为Multiple，那么好的是现在每个项目都被选中时会出现SelectedEarmark和SelectedGlyph ...但是，不好的是，SelectedBorder对于所有似乎由另一个视觉状态填充物触发的条目可见：
<VisualStateGroup x:Name="MultiSelectStates">
<VisualStateGroup.Transitions>
<VisualTransition From="ListMultiSelect" GeneratedDuration="0:0:0.15" To="NoMultiSelect"/>
<VisualTransition From="NoMultiSelect" GeneratedDuration="0:0:0.15" To="ListMultiSelect"/>
</VisualStateGroup.Transitions>
<VisualState x:Name="NoMultiSelect"/>
<VisualState x:Name="ListMultiSelect">
<Storyboard>
<DoubleAnimation Duration="0" To="0" Storyboard.TargetProperty="X" Storyboard.TargetName="CheckboxContainerTranslateTransform"/>
<DoubleAnimation Duration="0" To="{ThemeResource ListViewItemContentTranslateX}" Storyboard.TargetProperty="X" Storyboard.TargetName="ContentBorderTranslateTransform"/>
</Storyboard>
</VisualState>
<VisualState x:Name="GridMultiSelect">
<Storyboard>
<DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="SelectedBorder"/>
</Storyboard>
</VisualState>
</VisualStateGroup>
我似乎能够解决这个问题的唯一方法是从样式中删除这些视觉状态或通过更改边框XAML，因此它基本上不会绘制边框。 的耻辱是我无法使用内置风格;我基本上要提供自己的风格。我想，经过反思，这可能不是一件坏事......一旦你弄清楚项目风格如何运作，以及设置者等等。

使用FocusStates而不是SelectionStates。
<VisualStateGroup x:Name="FocusStates">
<VisualState x:Name="PointerFocused">
<Storyboard>
<DoubleAnimation Duration = "0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="CheckGlyph"/>
<DoubleAnimation Duration = "0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="SelectedCheckMark"/>
</Storyboard>
</VisualState>
<VisualState x:Name="Unfocused">
<Storyboard>
<DoubleAnimation Duration = "1" To="0" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="CheckGlyph"/>
<DoubleAnimation Duration = "1" To="0" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="SelectedCheckMark"/>
</Storyboard>
</VisualState>
</VisualStateGroup>
希望这会奏效。如果没有，那么您可以定义自己的自定义状态并在后面的代码中使用它。
我遇到了同样的问题。请参阅我的问题和答案以供参考。 Custom Selection States
