我有一个 ListBox与定制项目的风格。我希望该项目在选择时变大一点,并在取消选择时恢复到其原始大小。我尝试了几种解决方案,但似乎都没有奏效。我认为问题在于Storyboard.TargetProperty的正确设置.

我当前的 XAML 如下所示:

...
<ListBox.Resources>
<Style TargetType="{x:Type ListBoxItem}">
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="LayoutTransform.(ScaleTransform.ScaleX)" To="1.2" Duration="0:0:.3" AutoReverse="True"/>
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
</Trigger>
</Style.Triggers>
</Style>
</ListBox.Resources>
...

我的最终代码(已应用答案):
...
<ListBox.Resources>
<Style TargetType="{x:Type ListBoxItem}">
<Setter Property="RenderTransformOrigin" Value="0.5,0.5" />
<Setter Property="RenderTransform">
<Setter.Value>
<ScaleTransform />
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="RenderTransform.ScaleX" To="1.1" Duration="0:0:.1" />
<DoubleAnimation Storyboard.TargetProperty="RenderTransform.ScaleY" To="1.1" Duration="0:0:.1" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="RenderTransform.ScaleX" To="1.0" Duration="0:0:.1" />
<DoubleAnimation Storyboard.TargetProperty="RenderTransform.ScaleY" To="1.0" Duration="0:0:.1" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</Style.Triggers>
</Style>
</ListBox.Resources>
...

最佳答案

尝试使用以下代码:

...
<ListBox.Resources>
<Style TargetType="{x:Type ListBoxItem}">
<Setter Property="LayoutTransform">
<Setter.Value>
<ScaleTransform x:Name="scaleTransform" />
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="LayoutTransform.ScaleX" To="1.2" Duration="0:0:.3" AutoReverse="True"/>
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
</Trigger>
</Style.Triggers>
</Style>
</ListBox.Resources>
...
