我正在为我们的应用程序制作一个“基本样式”。我开始为我们的按钮制作一个“基本样式”,这将是一个很好的双梯度(我创建了一个有2行的模板,两行都有两点渐变)。
因此,基本按钮工作正常,现在我想基于该样式创建其他按钮。
这是基本按钮的代码:
<Style x:Key="BaseButtonStyle" TargetType="{x:Type Button}">
<Setter Property="Height" Value="24"/>
<Setter Property="Width" Value="150" />
<Setter Property="Foreground" Value="{DynamicResource OffWhiteBrush}"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="OuterBorder" BorderBrush="{DynamicResource GrayBorderBrush}" BorderThickness="2" CornerRadius="5">
<Grid x:Name="LayoutGrid">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Border x:Name="TopBorder" BorderBrush="{x:Null}" BorderThickness="0" CornerRadius="4,4,0,0" Background="{DynamicResource TopGrayGradientBrush}"/>
<Border x:Name="BottomBorder" BorderBrush="{x:Null}" BorderThickness="0" Grid.Row="1" CornerRadius="0,0,4,4" Background="{DynamicResource BottomGrayGradientBrush}"/>
<ContentPresenter x:Name="contentPresenter" Grid.RowSpan="2" HorizontalAlignment="Center" />
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Control.Foreground" TargetName="contentPresenter" Value="{DynamicResource DisabledBrush}"/>
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Margin" TargetName="OuterBorder" Value="1"/>
<Setter Property="Background" TargetName="TopBorder" Value="{DynamicResource TopGrayGradientBrush}"/>
<Setter Property="Background" TargetName="BottomBorder" Value="{DynamicResource BottomGrayGradientBrush}"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" TargetName="TopBorder" Value="{DynamicResource TopBlueGradientBrush}"/>
<Setter Property="Background" TargetName="BottomBorder" Value="{DynamicResource BottomBlueGradientBrush}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
当我创建第二个按钮时,我可以“基于”另一个样式:
<Style x:Key="RedButtonStyle" TargetType="{x:Type Button}" BasedOn="{StaticResource BaseButtonStyle}">
...
在网格中我已经命名了我的渐变:topborder和bottomborder。问题是我需要复制代码才能设置任何代码,因为redbuttonStyle不“知道”topborder或bottomborder:
<Style x:Key="RedButtonStyle" TargetType="{x:Type Button}" BasedOn="{StaticResource BaseButtonStyle}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="OuterBorder" BorderBrush="{DynamicResource GrayBorderBrush}" BorderThickness="2" CornerRadius="5">
<Grid x:Name="LayoutGrid">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Border x:Name="TopBorder" BorderBrush="{x:Null}" BorderThickness="0" CornerRadius="4,4,0,0" Background="{DynamicResource TopGrayGradientBrush}"/>
<Border x:Name="BottomBorder" BorderBrush="{x:Null}" BorderThickness="0" Grid.Row="1" CornerRadius="0,0,4,4" Background="{DynamicResource BottomGrayGradientBrush}"/>
<ContentPresenter x:Name="contentPresenter" Grid.RowSpan="2" HorizontalAlignment="Center" />
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Control.Foreground" TargetName="contentPresenter" Value="{DynamicResource DisabledBrush}"/>
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Margin" TargetName="OuterBorder" Value="1"/>
<Setter Property="Background" TargetName="TopBorder" Value="{DynamicResource TopGrayGradientBrush}"/>
<Setter Property="Background" TargetName="BottomBorder" Value="{DynamicResource BottomGrayGradientBrush}"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" TargetName="TopBorder" Value="{DynamicResource TopRedGradientBrush}"/>
<Setter Property="Background" TargetName="BottomBorder" Value="{DynamicResource BottomRedGradientBrush}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
这里的问题是我几乎重复了整个风格,而我只想改变IsMouseOver事件的两个渐变
我该如何处理?
PS。我看过这个WPF -- override style colors, best practice,但我无法弄清楚TemplateBinding:/
