对于我的生活,我无法弄清楚为什么下面的简单设置不起作用。我只是希望边框在加载后放大(“放大”),放大功能包含在资源样式中。但是当下面的XAML运行时,边框只会以100%的比例加载,不会发生动画。非常感谢您的帮助!

<Setter.Value>
<ScaleTransform/>
</Setter.Value>

<!-- ....... -->
<Border Style="{StaticResource SBorder}"/>
编辑:我没有显示上面的完整标记,因此可以保持简单,但我的完整标记位于下方。请注意,因为Border中有按钮,所以Border 在运行时具有高度/宽度。

如果以上是XAML
,请按以下步骤更改您的代码:
<Border Style="{StaticResource SBorder}" Background="Red" Height="200" Width="200"/>
您已将
VerticalAlignment
和HorizontalAlignment
设为Center
,而未设置为Height
&amp;边框中的Width
因此无法显示 一点都不给高度和高度宽度某个值或设置 我会VerticalAlignment
和HorizontalAlignment
到Stretch
看到Animation
会正常工作。如下:
<Style x:Key="SBorder" BasedOn="{StaticResource SZoomIn}" TargetType="Border">
<Setter Property="VerticalAlignment" Value="Stretch"/>
<Setter Property="HorizontalAlignment" Value="Stretch"/>
<Setter Property="RenderTransformOrigin" Value="0.5,0.5"/>
</Style>
如果您有其他控制层次结构,那么请更新相关内容,我会更新我的答案。
<强>更新强>
在您更新的标记中,边框将有Height
&amp;渲染时Width
。但SZoomIn
样式似乎与之前给出的XAML不同。您没有正确设置Storyboard.TargetProperty
属性。您在其中缺少RenderTransform
前缀。
所以解决方案是:
在
Storyboard
中XAML
替换Storyboard
中的XAML
。

所以,正如评论中所提到的,我在这里发布的代码确实可以正常工作。问题出在一个其他标记元素上,我从原始帖子中删除了。我创建了一个名为DraggableArea的类,它继承自ContentControl,这个元素包围了我的Border(参见下面的FULL标记)。 DraggableArea使用鼠标可以拖动任何内容。我把它留在了b / c我想每个人都会专注于那个而不是看周围的XAML,在那里我确定问题所在。事实证明我错了,像往常一样我的自定义代码导致了错误。不知道为什么虫子正在发生,但你去了。感谢所有的帮助!
<local:DraggableArea>
<Border x:Name="MainBorder" Style="{StaticResource SBorder}">
<StackPanel x:Name="MainStackPnl" Style="{StaticResource SStackPnl}">
<Button x:Name="ViewProjectsBtn" Content="View Projects" Style="{StaticResource STopBtn}" Click="ViewProjectsBtn_Click"/>
<Button x:Name="AboutBtn" Content="About" Style="{StaticResource SBtn}" Click="AboutBtn_Click"/>
<Button x:Name="ExitBtn" Content="Exit" Style="{StaticResource SBottomBtn}" Click="ExitBtn_Click"/>
</StackPanel>
</Border>
