Uwp图像缩放

Question

我正在尝试使用RenderTransform在网格视图项中缩放图像。缩放已成功执行，但缩放图像在网格视图项后面。如何把它摆在前面。

<VisualState x:Name="PointerOver">
 <Storyboard  >
  <DoubleAnimation Duration="0" Storyboard.TargetName="BorderRectangle" 
   Storyboard.TargetProperty="Opacity" To="1" />
    <ObjectAnimationUsingKeyFrames  
      Storyboard.TargetName="contentborderscale" 
      Storyboard.TargetProperty="ScaleY" >
       <DiscreteObjectKeyFrame KeyTime="0" Value="2" />
   </ObjectAnimationUsingKeyFrames>
   <ObjectAnimationUsingKeyFrames Storyboard.TargetName="contentborderscale" 
    Storyboard.TargetProperty="ScaleX">
     <DiscreteObjectKeyFrame  KeyTime="0" Value="2"  />
   </ObjectAnimationUsingKeyFrames>
   <PointerUpThemeAnimation Storyboard.TargetName="ContentPresenter" />
 </Storyboard>
</VisualState>

Answer 1

简而言之，您希望缩放GridViewItem的容器。

我检查了我对GridView selectedItem Popup (Method 2)的回答

方法2:在指针Hover上 XAML部件 C#部件 私有FrameworkElement lastPopUpElement = null；私有GridView_PointerEntered(对象发送方，PointerRoutedEventArgs e) { lastPopUpElement =lastPopUpElement= FrameworkElement)为FrameworkElement；Canvas.SetZIndex (lastPopUpElement，1)；lastPopUpElement.Scale(scaleX: 1.5f，scaleY: 1.5f，centerX: 50，centerY: 50，easingType: centerX)centerX()；}私有空(对象发送方，#e 20# e) { if ( !=空){(，0)；lastPopUpElement.Scale(centerX: 50，centerY: 50，easingType: EasingType.Sine).Start()；}} 样本输出
