我试图获得文本块的绝对位置，但我只是获得了之前元素的相对位置。

这是我的 XAML 代码：

<Grid Style="{StaticResource LayoutRootStyle}" x:Name="grid_wrapper">

    <Grid.Background>
      <ImageBrush ImageSource="Assets/background_menu.png" />
    </Grid.Background>

    <Grid x:Name="grid_main">
      <Grid.ColumnDefinitions>
        <ColumnDefinition Width="430" />
        <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>

    <Grid Grid.Column="0" x:Name="Sidebar">
      <Grid.Background>
        <SolidColorBrush Color="#000000" Opacity="0.5" />
      </Grid.Background>

      <Grid.RowDefinitions>
        <RowDefinition Height="100" />
        <RowDefinition Height="*" />
      </Grid.RowDefinitions>

      <Grid Grid.Row="0" x:Name="grid_mainCaption">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto"/>
            <ColumnDefinition Width="*"/>
        </Grid.ColumnDefinitions>

        <Button Grid.Row="0" Style="{StaticResource BackButtonStyleMain}" TabIndex="2" Margin="40,50,0,0" VerticalAlignment="Center" x:Name="backButton" Click="GoBack" IsEnabled="{Binding Frame.CanGoBack, ElementName=pageRoot}"/>
        <TextBlock x:Uid="Statistics" Margin="120,0,0,0" Text="Statistics" VerticalAlignment="Bottom" FontSize="33" Foreground="Gold" FontFamily="Assets/sui generis rg.ttf#Sui Generis"/>

      </Grid>
      <Grid x:Name="grid_captions" Grid.Row="1" Grid.Column="0" Margin="120,0,0,0">

我想拥有名为“Spielstatistik”的文本块的绝对 Y 位置，我已经尝试过如下操作：

float StatisticsNew::GetYPositionFromElement(UIElement^ obj)
{
auto transform = obj->TransformToVisual(nullptr);
auto point = transform->TransformPoint(Point(0,0));
return point.Y;
}

int YPosition = (int)GetYPositionFromElement(this->Spielstatistik);

YPosition 的值为 20。但 20 只是与之前元素的相对位置（因为 margin-top 设置为 20）。

如何获取元素的绝对位置？

我认为没有绝对位置之类的东西，但也许您可以调用TransformToVisual()传递 `Window::Current::Content （必要时进行强制转换）作为转换目标？
