我将此样式应用于网格单元格内的切换按钮:

<ToggleButton Grid.Column="1" IsChecked="{Binding Path=ObjectStatus}" Style="{StaticResource ResourceKey=OnOffSwitchToggleButton}" Margin="5,0,0,0"/>

我在 devexpress GridControl 中有另一个切换按钮,但没有出现此异常。

最佳答案

正如约翰所说,错误就在这一行

<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.Y)" Storyboard.TargetName="Switch">

无法遍历和查找 switch 中的属性,因此解决方案是为转换命名,然后直接引用转换

<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(TranslateTransform.Y)" Storyboard.TargetName="SwitchTranslate">

<Grid x:Name="Switch" Height="22" Canvas.Left="4.815" Canvas.Top="3.568" Width="22" RenderTransformOrigin="0.5,0.5">
<Grid.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform/>
<RotateTransform/>
<TranslateTransform x:Name="SwitchTranslate"/>
</TransformGroup>
