找不到目标名称

我在另一个堆栈面板上有两个堆栈面板，内部的具有可见性"折叠"，它的名称为"verborgen"。当鼠标悬停在内部堆栈面板上时，需要更改为可见性"可见"。所以我使用 TargetName="verborgen"

但是，我总是会想起"不认识"verborgen"这个名字

<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">

                            <Setter Property="Panel.ZIndex" Value="9999"/>
                        </Trigger>
                    </Style.Triggers>
                </Style>
            </DataTemplate.Resources>
        </DataTemplate>

找不到目标名称

找到它，问题不是数据模板样式，我只是使用了datatemplate.trigger
