在'System.Windows.Controls.ListView'的名稱範圍中找不到'ScaleTransform'名稱

Question

Whay我給出該錯誤''ScaleTransform'名稱無法在'System.Windows.Controls.ListView'的名稱範圍中找到」「。當ScaleTransform在另一個觸發器中，但是當我在Image.Triggers中設置它工作正常嗎？

 <ListView.ItemTemplate> 
          <DataTemplate> 
           <DockPanel> 
            <TextBlock DockPanel.Dock="Bottom" Text="{Binding Name}"/> 
            <Image x:Name="Img" Source="{Binding Source}" Height="128" Width="128" Focusable="True"> 
             <Image.RenderTransform> 
              <ScaleTransform x:Name="MyAnimatedScaleTransform" CenterX="25" CenterY="25" ScaleX="1" ScaleY="1" /> 
             </Image.RenderTransform> 
            </Image> 
           </DockPanel> 
          </DataTemplate> 
         </ListView.ItemTemplate> 
         <ListView.Triggers> 
          <EventTrigger RoutedEvent="ListView.SelectionChanged"> 
           <BeginStoryboard Name="myBeginStoryboard"> 
            <Storyboard> 
             <DoubleAnimation Storyboard.TargetName="MyAnimatedScaleTransform" Storyboard.TargetProperty="(ScaleTransform.ScaleX)" To="1.5" Duration="0:0:0.25" AutoReverse="True" /> 
             <DoubleAnimation Storyboard.TargetName="MyAnimatedScaleTransform" Storyboard.TargetProperty="(ScaleTransform.ScaleY)" To="1.5" Duration="0:0:0.25" AutoReverse="True"/> 
            </Storyboard> 
           </BeginStoryboard> 
          </EventTrigger> 
         </ListView.Triggers> 
        </ListView> 

，我嘗試也沒有工作：

<ListView.ItemTemplate> 
          <DataTemplate> 
           <DockPanel> 
            <TextBlock DockPanel.Dock="Bottom" Text="{Binding Name}"/> 
            <Image x:Name="Img" Source="{Binding Source}" Height="128" Width="128" Focusable="True"> 
             <Image.RenderTransform> 
              <ScaleTransform x:Name="MyAnimatedScaleTransform" CenterX="25" CenterY="25" ScaleX="1" ScaleY="1" /> 
             </Image.RenderTransform> 
            </Image> 
           </DockPanel> 
          </DataTemplate> 
         </ListView.ItemTemplate> 
         <ListView.Triggers> 
          <EventTrigger RoutedEvent="ListView.SelectionChanged"> 
           <BeginStoryboard Name="myBeginStoryboard"> 
            <Storyboard> 
             <DoubleAnimation Storyboard.Target="{Binding MyAnimatedScaleTransform}" Storyboard.TargetProperty="(ScaleTransform.ScaleX)" To="1.5" Duration="0:0:0.25" AutoReverse="True" /> 
             <DoubleAnimation Storyboard.Target="{Binding MyAnimatedScaleTransform}" Storyboard.TargetProperty="(ScaleTransform.ScaleY)" To="1.5" Duration="0:0:0.25" AutoReverse="True"/> 
            </Storyboard> 
           </BeginStoryboard> 
          </EventTrigger> 
         </ListView.Triggers> 
        </ListView>

我發現，在DataTemplate中的控制器無法訪問，所以我改變我的鱈魚的XAML到：

<ListView.ItemTemplate> 
         <DataTemplate> 
          <DockPanel> 
           <TextBlock DockPanel.Dock="Bottom" Text="{Binding Name}"/> 
           <Image x:Name="Img" Source="{Binding Source}" Height="128" Width="128" Focusable="True"> 
            <Image.RenderTransform> 
             <ScaleTransform x:Name="MyAnimatedScaleTransform" CenterX="25" CenterY="25" ScaleX="1" ScaleY="1" /> 
            </Image.RenderTransform> 
            <Image.Triggers> 
             <EventTrigger RoutedEvent="Image.MouseDown"> 
              <BeginStoryboard Name="myBeginStoryboard"> 
               <Storyboard> 
                <DoubleAnimation Storyboard.TargetName="MyAnimatedScaleTransform" Storyboard.TargetProperty="(ScaleTransform.ScaleX)" To="1.5" Duration="0:0:0.25" AutoReverse="True" /> 
                <DoubleAnimation Storyboard.TargetName="MyAnimatedScaleTransform" Storyboard.TargetProperty="(ScaleTransform.ScaleY)" To="1.5" Duration="0:0:0.25" AutoReverse="True"/> 
               </Storyboard> 
              </BeginStoryboard> 
             </EventTrigger> 
            </Image.Triggers> 
           </Image> 
          </DockPanel> 
         </DataTemplate> 
        </ListView.ItemTemplate> 

現在我已經返回到我的主要問題，當我第一次動畫結束（逆向）之前第二次點擊圖像時，圖像不會恢復到原始大小。
