我正在尝试使用RenderTransform缩放gridview项目中的图像。缩放比例 已成功执行，但缩放图像位于gridview项目后面。如何把它带到前面

我核对我的答案

方法2：指针悬停 XAML部件

样本输出

<GridView Height="200">
    <GridView.ItemTemplate>
        <DataTemplate x:DataType="local:ItemSource">
            <Grid Width="100" Height="100" PointerEntered="GridView_PointerEntered" PointerExited="GridView_PointerExited">
                <!-- Content -->
            </Grid>
        </DataTemplate>
    </GridView.ItemTemplate>
    <GridView.ItemsPanel>
        <ItemsPanelTemplate>
            <ItemsWrapGrid VerticalAlignment="Center" HorizontalAlignment="Center"/>
        </ItemsPanelTemplate>
    </GridView.ItemsPanel>
</GridView>

FrameworkElement lastPopUpElement = null;
private void GridView_PointerEntered(object sender, PointerRoutedEventArgs e)
{
    lastPopUpElement = VisualTreeHelper.GetParent(VisualTreeHelper.GetParent(sender as FrameworkElement) as FrameworkElement) as FrameworkElement;
    Canvas.SetZIndex(lastPopUpElement, 1);
    lastPopUpElement.Scale(scaleX: 1.5f, scaleY: 1.5f, centerX: 50, centerY: 50, easingType: EasingType.Sine).Start();
}

private void GridView_PointerExited(object sender, PointerRoutedEventArgs e)
{
    if (lastPopUpElement != null)
    {
        Canvas.SetZIndex(lastPopUpElement, 0);
        lastPopUpElement.Scale(centerX: 50, centerY: 50, easingType: EasingType.Sine).Start();
    }
}
