我有一个GridView，它使用了DataTemplateSelector。当DataTemplateSelector设置在GridView像这样它工作正常：与ItemContainerStyle一起使用DataTemplateSelector
<GridView x:Name="PayeesGridView"
IsItemClickEnabled="True"
ItemTemplateSelector="{StaticResource PayeeTemplateSelector}"
ItemsSource="{Binding FilteredPayees,
Mode=OneWay}"
Padding="5"
SelectionMode="None">
<interactivity:Interaction.Behaviors>
<core:EventTriggerBehavior EventName="ItemClick">
<core:CallMethodAction MethodName="GridViewItemClick" TargetObject="{Binding Mode=OneWay}" />
</core:EventTriggerBehavior>
</interactivity:Interaction.Behaviors>
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<ItemsWrapGrid x:Name="ItemWrapGrid" />
</ItemsPanelTemplate>
</GridView.ItemsPanel>
<GridView.ItemContainerStyle>
<Style TargetType="GridViewItem">
<Setter Property="Margin" Value="5" />
</Style>
</GridView.ItemContainerStyle>
</GridView>
不过，我想设置ItemContainerStyle内的DataTemplate使我能够使用VisualStateManager。我想声明它是这样的：
<GridView x:Name="PayeesGridView"
IsItemClickEnabled="True"
ItemsSource="{Binding FilteredPayees,
Mode=OneWay}"
Padding="5"
SelectionMode="None">
<interactivity:Interaction.Behaviors>
<core:EventTriggerBehavior EventName="ItemClick">
<core:CallMethodAction MethodName="GridViewItemClick" TargetObject="{Binding Mode=OneWay}" />
</core:EventTriggerBehavior>
</interactivity:Interaction.Behaviors>
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<ItemsWrapGrid x:Name="ItemWrapGrid" />
</ItemsPanelTemplate>
</GridView.ItemsPanel>
<GridView.ItemContainerStyle>
<Style TargetType="GridViewItem">
<Setter Property="Margin" Value="5" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="GridViewItem">
<Grid>
<Grid.Background>
<SolidColorBrush x:Name="GridBackground" Color="Transparent" />
</Grid.Background>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal" />
<VisualState x:Name="PointerOver">
<VisualState.Setters>
<Setter Target="GridBackground.Color" Value="Green" />
</VisualState.Setters>
<Storyboard />
</VisualState>
<VisualState x:Name="Pressed">
<VisualState.Setters>
<Setter Target="GridBackground.Color" Value="#36B536" />
</VisualState.Setters>
<Storyboard />
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<ContentPresenter Content="{TemplateBinding Content}"
ContentTemplate="{TemplateBinding ContentTemplate}"
ContentTemplateSelector="{StaticResource PayeeTemplateSelector}" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</GridView.ItemContainerStyle>
</GridView>
使用ContentPresenter并指定ContentTemplateSelector以同样的方式为ItemTemplateSelector是在GridView。这样做，GridView只显示每个Payee的对象视图。 VisualStates正常工作，但它没有使用我定义的DataTemplate。
的DataTemplates都在Page.Resources定义，像这样：
<DataTemplate x:Key="OpenPayeeDataTemplate" x:DataType="models:Payee">
<Grid>
<Border Width="230"
Height="230"
Background="White"
BorderBrush="#36B536"
BorderThickness="4">
<Grid Margin="5,0,5,0">
<Image Width="160"
Height="160"
Source="{x:Bind LogoBase64, Converter={StaticResource Base64StringToImageSourceConverter}}" />
<TextBlock VerticalAlignment="Top"
FontSize="14"
FontWeight="Bold"
Foreground="Black"
Text="{x:Bind CompanyName}"
TextAlignment="Left"
TextWrapping="WrapWholeWords" />
<TextBlock VerticalAlignment="Bottom"
FontSize="12"
FontWeight="Bold"
Foreground="Black"
Text="{x:Bind AccountNickname}"
TextAlignment="Right"
TextWrapping="WrapWholeWords" />
</Grid>
</Border>
</Grid>
</DataTemplate>
<DataTemplate x:Key="ClosedPayeeDataTemplate" x:DataType="models:Payee">
<Grid>
<Border Width="230"
Height="230"
Background="White"
BorderBrush="#36B536"
BorderThickness="4">
<Grid Margin="5,0,5,0">
<Image Width="160"
Height="160"
Source="{x:Bind LogoBase64, Converter={StaticResource Base64StringToImageSourceConverter}}" />
<TextBlock VerticalAlignment="Top"
FontSize="14"
FontWeight="Bold"
Foreground="Black"
Text="{x:Bind CompanyName}"
TextAlignment="Left"
TextWrapping="WrapWholeWords" />
<TextBlock VerticalAlignment="Bottom"
FontSize="12"
FontWeight="Bold"
Foreground="Black"
Text="{x:Bind AccountNickname}"
TextAlignment="Right"
TextWrapping="WrapWholeWords" />
</Grid>
</Border>
<Border Width="230"
Height="230"
Background="Gray"
Opacity="0.75" />
</Grid>
</DataTemplate>
<converters:PayeeDataTemplateSelector x:Name="PayeeTemplateSelector"
ClosedPayeeDataTemplate="{StaticResource ClosedPayeeDataTemplate}"
OpenPayeeDataTemplate="{StaticResource OpenPayeeDataTemplate}" />
另外，我曾尝试使用DataTemplate S的内部的VisualStateManager，但他们不会被触发，那么我就可以使用它外部的DataTemplate，因此希望在ItemContainerStyle内使用ContentPresenter。
我做了一些类似的一些ListViewItem s，但他们不使用DataTemplateSelector，所以我没有遇到同样的问题。有没有办法让VisualStateManager在DataTemplate之内工作，或者DataTemplateSelector能够在ContentPresenter之内工作？

这里是我试图把在Styles/DataTemplates.xaml的XAML。风格正在应用，但我没有得到任何VisualStates被触发。

的VisualState的工作完全正常的设置，直接使用GridView.ItemContainerStyle设置Template，但不是在一个单独的资源文件从DataTemplate想它的时候的时候。有任何想法吗？
我试图用你在'Kliva'中使用它的方式实现'VisualStateManager'，而且我还没有得到任何改变。我将XAML发布到我原来的帖子中，因此它格式正确... –
奇怪的是第一次看起来你的DataTemplate xaml看起来是正确的：/ – Depechie
是的，我也这么认为。至少我能够使用从VisualStateManager分离出来的模板。我想，总比没有好。 –
