我在寻找一种方法来改变
图像
在故事板中,或者更具体地说,更改
Source
指向新图像资源的图像的属性。似乎有一个
StringAnimationUsingKeyFrames
和A
DiscreteStringKeyFrame
但这不起作用(据我所知),因为图像的源属性是类型
ImageSource
我现在的故事板是这样的
<Storyboard x:Key="TransitionImage">
<DoubleAnimationUsingKeyFrames
BeginTime="00:00:00"
Storyboard.TargetName="image"
Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleX)">
<SplineDoubleKeyFrame KeyTime="00:00:00.7000000" Value="0.2"/>
<SplineDoubleKeyFrame KeyTime="00:00:01.5000000" Value="1"/>
</DoubleAnimationUsingKeyFrames>
<StringAnimationUsingKeyFrames
BeginTime="00:00:00"
Storyboard.TargetName="image"
Storyboard.TargetProperty="(Image.Source)">
<!-- This does not work -->
<DiscreteStringKeyFrame KeyTime="00:00:00.7000000" Value="check_24.png"/>
</StringAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames
BeginTime="00:00:00"
Storyboard.TargetName="image"
Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleY)">
<SplineDoubleKeyFrame KeyTime="00:00:00.7000000" Value="0.2"/>
<SplineDoubleKeyFrame KeyTime="00:00:01.5000000" Value="1"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
和图像
<Image x:Name="image"
Source="delete_24.png"
Width="32" Height="32"
Margin="8"
RenderTransformOrigin="0.5,0.5">
<Image.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform/>
<RotateTransform/>
<TranslateTransform/>
</TransformGroup>
</Image.RenderTransform>
</Image>
我能换一下吗

作为故事板的一部分还是我走运了?
