我正在尝试为超链接控件设置不同的样式。新样式基于与设置为控件的先前样式相同的基本样式,并且 Foreground 属性已被覆盖为新颜色。但是在应用程序中,前景不会改变。
几点注意事项:如果覆盖属性是 FontSize,事情似乎工作正常。
在 Silverlight 4 中,一切正常。
如果我删除了 BasedOn 属性(不要从基类派生),事情就可以正常工作。
第一次设置样式有效,但随后尝试更改样式无效。
如果我复制样式并更改前景色,则一切正常。
*一切正常=前景正确改变。
基本风格:
<Style TargetType="HyperlinkButton" x:Key="NormalHyperlinkStyle">
<Setter Property="FontFamily" Value="{StaticResource ContentFontFamily}"/>
<Setter Property="FontSize" Value="{StaticResource DataGridFontSize}"/>
<Setter Property="Background" Value="Transparent" />
<Setter Property="Cursor" Value="Hand" />
<Setter Property="Foreground" Value="{StaticResource BaseColor4}" />
<Setter Property="HorizontalContentAlignment" Value="Left" />
<Setter Property="Padding" Value="1"/>
<Setter Property="VerticalContentAlignment" Value="Top" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="HyperlinkButton">
<Grid Background="{TemplateBinding Background}" Cursor="{TemplateBinding Cursor}">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal" />
<VisualState x:Name="MouseOver">
<Storyboard>
<ColorAnimation Duration="0" To="{StaticResource AccentColor}" Storyboard.TargetProperty="(Control.Foreground).(SolidColorBrush.Color)" Storyboard.TargetName="contentPresenter" />
<DoubleAnimation Duration="0" To="1.0" Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="Underline" />
</Storyboard>
</VisualState>
<VisualState x:Name="Pressed" />
<VisualState x:Name="Disabled">
<Storyboard>
<ColorAnimation Duration="0" To="#FFA0A0A0" Storyboard.TargetProperty="(Control.Foreground).(SolidColorBrush.Color)" Storyboard.TargetName="contentPresenter" />
</Storyboard>
</VisualState>
</VisualStateGroup>
<VisualStateGroup x:Name="FocusStates">
<VisualState x:Name="Focused">
<Storyboard>
<DoubleAnimation Duration="0" Storyboard.TargetName="FocusVisualElement" Storyboard.TargetProperty="(FrameworkElement.Opacity)" To="1" />
</Storyboard>
</VisualState>
<VisualState x:Name="Unfocused" />
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<StackPanel Margin="{TemplateBinding Padding}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" UseLayoutRounding="True">
<ContentControl x:Name="contentPresenter" Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}" Foreground="{TemplateBinding Foreground}" />
<Rectangle x:Name="Underline" Height="1" VerticalAlignment="Bottom" Fill="{StaticResource AccentColorBrush}" Margin="0,1,0,2" Opacity="0" />
</StackPanel>
<Rectangle x:Name="FocusVisualElement" IsHitTestVisible="False" Margin="0" Opacity="0" RadiusX="2" RadiusY="2" Stroke="{StaticResource FocusVisualBrush}" StrokeThickness="{StaticResource FocusVisualStrokeThickness}" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
派生风格:
<Style x:Key="ToolbarHyperlinkSelectedStyle" TargetType="HyperlinkButton" BasedOn="{StaticResource NormalHyperlinkStyle}">
<Setter Property="Foreground" Value="{StaticResource AccentColor}" />
</Style>
代码背后:
selectedButton.Style =
(Style)Application.Current.Resources["ToolbarHyperlinkSelectedStyle"];
