[英]WPF Storyboard: DoubleAnimation Works On Opacity But Not TranslateTransform?
[英]WPF Storyboard with TranslateTransform
我有一個情節提要,例如
<Storyboard x:Key="NewsFlow">
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.Y)"
Storyboard.TargetName="TextBlock"
RepeatBehavior="Forever" AutoReverse="True">
<EasingDoubleKeyFrame KeyTime="0:0:0" Value="-80"/>
<EasingDoubleKeyFrame KeyTime="0:0:2" Value="80"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
和網格
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="1*" />
<RowDefinition Height="100" />
<RowDefinition Height="1*" />
</Grid.RowDefinitions>
<Border Grid.Row="1" Background="BlanchedAlmond"></Border>
<TextBlock Grid.Row="1" Text="News" FontSize="40" HorizontalAlignment="Center" ></TextBlock>
</Grid>
Grid.Row =“ 1”是新聞查看區域(黃線)
但是Storyboard忽略了Grid.RowDefinitions之類的圖片
我要這樣
如果創建情節提要,則應如下所示:
<Storyboard x:Key="NewsFlow">
<ThicknessAnimationUsingKeyFrames Storyboard.TargetProperty="Margin"
Storyboard.TargetName="TextBlock"
RepeatBehavior="Forever" AutoReverse="True">
<EasingThicknessKeyFrame KeyTime="0:0:0" Value="0,0,0,150"/>
<EasingThicknessKeyFrame KeyTime="0:0:1" Value="0,0,0,0"/>
<EasingThicknessKeyFrame KeyTime="0:0:2" Value="0, 150,0,0"/>
</ThicknessAnimationUsingKeyFrames>
</Storyboard>
但是Margin落后於TranslateTransform。 和Textblock的另一端在播放動畫時壞了
謝謝,問候
<Window.Resources>
<Storyboard x:Key="NewsFlow">
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="Height"
Storyboard.TargetName="News"
RepeatBehavior="Forever" AutoReverse="True">
<EasingDoubleKeyFrame KeyTime="0:0:00" Value="-80"/>
<EasingDoubleKeyFrame KeyTime="0:0:02" Value="80"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
</Window.Resources>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="100" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Border Grid.Row="1" Background="BlanchedAlmond"/>
<TextBlock Grid.Row="1" x:Name="News" Text="News" FontSize="40" HorizontalAlignment="Center">
<TextBlock.Triggers>
<EventTrigger RoutedEvent="Loaded">
<BeginStoryboard Storyboard="{StaticResource NewsFlow}"/>
</EventTrigger>
</TextBlock.Triggers>
</TextBlock>
</Grid>
