我正在创建一个基本样式。我正在使用继承来实现我的基本样式。我知道如何在派生类上添加属性,但我不知道如何更改属性。让我给你举个例子:
假设我有这种基本风格:
<!-- SrollViewer ScrollBar Repeat Buttons (at each end) -->
<Style x:Key="ScrollBarLineButton" TargetType="{x:Type RepeatButton}">
<Setter Property="SnapsToDevicePixels" Value="True"/>
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="Focusable" Value="false"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RepeatButton}">
<Border
Name="Border"
Margin="1"
CornerRadius="2"
Background="WhiteSmoke"
BorderThickness="1">
<Image Stretch="Uniform" Source="/FilesPro;component/Images/scrollArrow.png" Height="40" VerticalAlignment="Center" HorizontalAlignment="Center" Width="52" >
<Image.RenderTransform>
<TransformGroup>
<ScaleTransform ScaleY="-1" />
<TranslateTransform Y="40"/>
<SkewTransform/>
<RotateTransform/>
<TranslateTransform/>
</TransformGroup>
</Image.RenderTransform>
</Image>
<!--
<Path
HorizontalAlignment="Center"
VerticalAlignment="Center"
Fill="{StaticResource GlyphBrush}"
Data="{Binding Path=Content,
RelativeSource={RelativeSource TemplatedParent}}" >
</Path>
-->
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
我想创建一个新样式,它具有与 ScrollBarLineButton 相同的属性,但图像从 scaleY=1 而不是 -1 转换。
当我做:
<Style x:Key="ScrollBarLineButtonVerticalUp" BasedOn="{StaticResource ScrollBarLineButton}" TargetType="{x:Type RepeatButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RepeatButton}">
<Border>
<Image Stretch="Uniform" Source="/FilesPro;component/Images/scrollArrow.png" Height="40" VerticalAlignment="Center" HorizontalAlignment="Center" Width="52" >
<Image.RenderTransform>
<TransformGroup>
<ScaleTransform ScaleY="1" />
....
...
边框不再具有其基本样式边距、背景颜色等。我如何从样式继承并只更改一个属性。我知道我可以复制粘贴,但我会改变很多,如果我在一个地方改变它,它会在所有其他地方改变,这很方便。
