TargetName找不到

Question

我有兩個堆疊面板在另一個，內部有一個可見性「摺疊」，它的名稱爲「verborgen」 當mouseOver內部堆疊面板需要更改爲可見性時 因此我使用TargetName =「verborgen」

但是，它總是回到我verborgen‘「名稱’無法識別

<DataTemplate x:Key="WastebinTemplate"> 
      <ContentControl map:MapLayer.Position="{Binding GeoLocation}"> 
       <ContentControl.Content> 
        <StackPanel> 
          <TextBlock Background="{StaticResource Blue}" Text="{Binding Barcode}"/> 
         <StackPanel x:Name="verborgen" Visibility="Collapsed" Background="{StaticResource Orange}"> 
          <Button Name="btnRemove" Content="Remove wastebin" Click="btnRemove_Click"> 
          </Button> 
          <Label>Adres</Label> 
          <TextBox Name="txbAdres" Text="{Binding Address}"/> 
          <Label>Location type</Label> 
          <ComboBox ItemsSource="{Binding Source={StaticResource LocationTypeInstance}, Path=LocationTypes}" 
             DisplayMemberPath="Description" SelectedItem="{Binding LocationType}" SelectedValuePath="ID" SelectedValue="{Binding LocationType.ID}" /> 
          <Label>Capaciteit</Label> 
          <Slider Minimum="0" Maximum="100" TickFrequency="10" Value="{Binding Capacity}"></Slider> 
         </StackPanel> 
        </StackPanel> 
       </ContentControl.Content> 
      </ContentControl> 
      <DataTemplate.Resources> 
       <Style TargetType="StackPanel"> 
        <Style.Triggers> 
         <Trigger Property="IsMouseOver" Value="True"> 
          <Setter Property="Visibility" Value="Visible" TargetName="verborgen" /> 
          <Setter Property="Panel.ZIndex" Value="9999"/> 
         </Trigger> 
        </Style.Triggers> 
       </Style> 
      </DataTemplate.Resources> 
     </DataTemplate>

找到了，問題是我只是使用了datatemplate.trigger一個DataTemplate的風格，而不是
