在WPF中,根据数据绑定内容选择ItemContainerStyle

在#WPF中你有ItemTemplateSelectors。但是,您是否还可以根据绑定对象的数据类型选择ItemContainerStyle?

我正在对散点图进行数据绑定。我想根据DataContext中的对象设置生成的ScatterViewItems的一些属性。对于样式,类似于ItemTemplateSelector的机制会很棒。那可能吗?我现在绑定到我正在显示的对象中的属性以获得效果,但这感觉就像开销和太复杂(最重要的是,我们的XU设计师不能自己做的事情)。

这是我现在使用的XAML。非常感谢您的帮助。

      <s:ScatterView x:Name="topicsViewer">
   <s:ScatterView.ItemTemplateSelector>
    <local:TopicViewerDataTemplateSelector>
     <DataTemplate DataType="{x:Type mvc:S7VideoTopic}">
      <Grid>
       <ContentPresenter Content="{Binding MediaElement}"  />
       <s:SurfaceButton Visibility="{Binding MailToVisible}" x:Name="mailto" Tag="{Binding Titel}" Click="mailto_Click" HorizontalAlignment="Right" VerticalAlignment="Top" Background="Transparent" Width="62" Height="36">
        <Image Source="/Resources/MailTo.png" />
       </s:SurfaceButton>
       <StackPanel Orientation="Horizontal" VerticalAlignment="Bottom" HorizontalAlignment="Center" Height="32">
        <s:SurfaceButton Tag="{Binding MediaElement}" x:Name="btnPlay" Click="btnPlay_Click">
         <Image Source="/Resources/control_play.png" />
        </s:SurfaceButton>
        <s:SurfaceButton Tag="{Binding MediaElement}" x:Name="btnPause" Click="btnPause_Click">
         <Image Source="/Resources/control_pause.png" />
        </s:SurfaceButton>
        <s:SurfaceButton Tag="{Binding MediaElement}" x:Name="btnStop" Click="btnStop_Click">
         <Image Source="/Resources/control_stop.png" />
        </s:SurfaceButton>
       </StackPanel>
      </Grid>
     </DataTemplate>
     <DataTemplate DataType="{x:Type mvc:S7ImageTopic}">
      <Grid>
       <ContentPresenter Content="{Binding Resource}" />
       <s:SurfaceButton Visibility="{Binding MailToVisible}" x:Name="mailto" Tag="{Binding Titel}" Click="mailto_Click" HorizontalAlignment="Right" VerticalAlignment="Top" Background="Transparent" Width="62" Height="36">
        <Image Source="/Resources/MailTo.png" />
       </s:SurfaceButton>
      </Grid>
     </DataTemplate>
     <DataTemplate DataType="{x:Type local:Kassa}">
      <ContentPresenter Content="{Binding}" Width="300" Height="355" />
     </DataTemplate>
    </local:TopicViewerDataTemplateSelector>
   </s:ScatterView.ItemTemplateSelector>
   <s:ScatterView.ItemContainerStyle>
    <Style TargetType="s:ScatterViewItem">
     <Setter Property="MinWidth" Value="200" />
     <Setter Property="MinHeight" Value="150" />
     <Setter Property="MaxWidth" Value="800" />
     <Setter Property="MaxHeight" Value="700" />
     <Setter Property="Width" Value="{Binding DefaultWidth}" />
     <Setter Property="Height" Value="{Binding DefaultHeight}" />
     <Setter Property="s:ScatterViewItem.CanMove" Value="{Binding CanMove}" />
     <Setter Property="s:ScatterViewItem.CanScale" Value="{Binding CanScale}" />
     <Setter Property="s:ScatterViewItem.CanRotate" Value="{Binding CanRotate}" />
     <Setter Property="Background" Value="Transparent" />
    </Style>
   </s:ScatterView.ItemContainerStyle>
  </s:ScatterView>
