Silverlight按钮鼠标悬停效果
本文关键字：悬停 鼠标 按钮 Silverlight | 更新日期: 2023-09-27 18:02:23
我创建了一个带有样式的按钮，但是在创建按钮样式之后，它失去了按钮的默认效果，当我直接在按钮中添加属性时，我会得到那些默认效果，比如当我点击时，我可以看到蓝色背景。我也试着把视觉管理器，但它不工作。有人可以帮助我知道我做错了什么
我的按钮样式:
<Style TargetType="Button" x:Key="MenuButtonStyle">
<Setter Property="HorizontalAlignment" Value="Stretch"/>
<Setter Property="Foreground" Value="Black"/>
<Setter Property="FontFamily" Value="Sitka Heading"/>
<Setter Property="FontSize" Value="20"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="Pressed">
<Storyboard>
<ColorAnimation Duration="0" Storyboard.TargetName="ButtonTextElement"
Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)"
To="Blue"/>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)"
Storyboard.TargetName="normalImage">
<DiscreteObjectKeyFrame KeyTime="0">
<DiscreteObjectKeyFrame.Value>
<Visibility>Collapsed</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)"
Storyboard.TargetName="mouseOverImage">
<DiscreteObjectKeyFrame KeyTime="0">
<DiscreteObjectKeyFrame.Value>
<Visibility>Visible</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
<VisualState x:Name="MouseOver">
<Storyboard>
<ColorAnimation Duration="0" Storyboard.TargetName="ButtonTextElement"
Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)"
To="Blue"/>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)"
Storyboard.TargetName="normalImage">
<DiscreteObjectKeyFrame KeyTime="0">
<DiscreteObjectKeyFrame.Value>
<Visibility>Collapsed</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)"
Storyboard.TargetName="mouseOverImage">
<DiscreteObjectKeyFrame KeyTime="0">
<DiscreteObjectKeyFrame.Value>
<Visibility>Visible</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Border BorderBrush="Black" BorderThickness="0,0,0,0.5" Margin="30,0,0,0"
Grid.ColumnSpan="2"/>
<TextBlock x:Name="ButtonTextElement"
Text="{TemplateBinding Content}" Margin="30,0"
Foreground="{TemplateBinding Foreground}" Grid.Column="0"
VerticalAlignment="{TemplateBinding VerticalAlignment}" />
<Image x:Name="normalImage" Source="/Assets/menu-arrow-left.png"
Grid.Column="1" Stretch="None" HorizontalAlignment="Right"
Margin="0,0,30,0" />
<Image x:Name="mouseOverImage" Source="/Assets/menu-arrow-left-hover.png"
Grid.Column="1" Stretch="None" HorizontalAlignment="Right"
Visibility="Collapsed" Margin="0,0,30,0" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
我也改变了VisualStateManager像这样
<ColorAnimation Storyboard.TargetName="MouseOverVisualElement"
Storyboard.TargetProperty="TextBlock.Foreground" To="Red" />
My Button Tag
<Button Style="{StaticResource MenuButtonStyle}" Content="Home"/>
你的模板有几个问题。首先:您必须确保由Storyboard.TargetName标识的元素及其由Storyboard.TargetProperty标识的属性(您想要更改)实际上是有意义的。您可以更改SolidColorBrush的颜色，也可以为Textblock.Foreground属性使用SolidColorBrush，但是您不能直接设置前景属性的颜色，因为前景实际上是Brush(而不是Color)。其次:如果您覆盖控件的模板，则必须提供原始模板中的所有VisualStates，这意味着您也必须定义FocusStates。下面是一个模板，它可以做你想做的事情:
<ControlTemplate TargetType="Button">
<Grid>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver">
<Storyboard>
<ColorAnimation
Duration="0"
Storyboard.TargetName="ButtonTextElement"
Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)"
To="Red"/>
</Storyboard>
</VisualState>
<VisualState x:Name="Pressed">
<Storyboard>
<ColorAnimation
Duration="0"
Storyboard.TargetName="Background"
Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)"
To="#FF6DBDD1"/>
<ColorAnimation
Duration="0"
Storyboard.TargetName="ButtonTextElement"
Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)"
To="Red"/>
</Storyboard>
</VisualState>
<VisualState x:Name="Disabled">
<Storyboard>
<DoubleAnimation
Duration="0"
Storyboard.TargetName="DisabledVisualElement"
Storyboard.TargetProperty="Opacity"
To=".55"/>
</Storyboard>
</VisualState>
</VisualStateGroup>
<VisualStateGroup x:Name="FocusStates">
<VisualState x:Name="Focused">
<Storyboard>
<DoubleAnimation
Duration="0"
Storyboard.TargetName="FocusVisualElement"
Storyboard.TargetProperty="Opacity"
To="1"/>
</Storyboard>
</VisualState>
<VisualState x:Name="Unfocused"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Border
x:Name="Background"
Background="White"/>
<TextBlock
x:Name="ButtonTextElement"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
Text="{TemplateBinding Content}"
FontSize="20" FontFamily="Sitka Heading"
Foreground="Black"/>
<Rectangle x:Name="DisabledVisualElement" Fill="#FFFFFFFF" Opacity="0" IsHitTestVisible="false" />
<Rectangle x:Name="FocusVisualElement" Margin="1" Stroke="#FF6DBDD1" StrokeThickness="1" Opacity="0" IsHitTestVisible="false" />
</Grid>
</ControlTemplate>
默认的按钮样式可以在msdn上找到

确保VisualStateManager。VisualStateGroups是ControlTemplate根元素的直接子元素。在你的例子中，你的根元素是一个Border，所以把VisualStateManager的东西直接放在Border标签下面。
