更改动画中的边框背景颜色
Change Border background color in animation
我是XAML区的新手,只是想了解一下VSM。当我在 StoryBoard 中添加内容时,总是会提示相同的错误。如下:
无法解析指定对象的 TargetProperty Background.Color。
<phone:PhoneApplicationPage.Resources>
<ControlTemplate x:Key="ButtonControlTemplate1" TargetType="Button">
<Border
BorderThickness="{TemplateBinding BorderThickness}"
Height="{TemplateBinding Height}"
Width="{TemplateBinding Width}"
Margin="{TemplateBinding Margin}"
Padding="{TemplateBinding Padding}"
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
Name="btnBorder">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver">
<Storyboard>
<ColorAnimation Duration="0"
To="Blue"
Storyboard.TargetName="btnBorder"
Storyboard.TargetProperty="Background.Color"
/>
</Storyboard>
</VisualState>
<VisualState x:Name="Pressed"/>
<VisualState x:Name="Disabled"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<ContentPresenter
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" >
</ContentPresenter>
</Border>
</ControlTemplate>
</phone:PhoneApplicationPage.Resources>
<Button
x:Name="btnSubmit"
Grid.Row="3"
Grid.Column="0"
Grid.ColumnSpan="2"
Content="Login"
IsEnabled="False"
Click="btnSubmit_Click"
Margin="0"
BorderThickness="2"
BorderBrush="White"
Background="Aqua"
Padding="15"
Template="{StaticResource ButtonControlTemplate1}"
/>
为什么以及如何修复它,谢谢!
您的视觉状态应该是 PointerOver
而不是 MouseOver
。
即便如此 ColorAnimation
对我没有任何作用。然而,这确实:
<VisualState x:Name="PointerOver">
<Storyboard>
<ObjectAnimationUsingKeyFrames
Storyboard.TargetName="btnBorder"
Storyboard.TargetProperty="Background">
<DiscreteObjectKeyFrame KeyTime="0" Value="Blue" />
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
注意目标 属性 是 Background
而不是 Background.Color
。
