C# 使用BasedOn更改控件属性

我有一个带有一些按钮的用户控件。我需要更改按钮的背景颜色，但保留所有其他属性和颜色，如鼠标悬停事件

我使用了下面的代码，我希望它能够基于

{StaticResource{x:Type Button}}}

定义

UniqueButton1

，但是更改background属性来定义我自己的颜色

<UserControl x:Class="Project.Detail"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             mc:Ignorable="d" 
             d:DesignHeight="30" d:DesignWidth="800" BorderBrush="#FF5380E7" BorderThickness="0,0,0,1" xmlns:my="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero">
    <UserControl.Resources>
        <Style  x:Key="UniqueButton1" TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type Button}}"  >
            <Setter Property="Background">
                <Setter.Value>
                <LinearGradientBrush EndPoint="0,1">
                    <GradientStop Color="#FFF896CE" Offset="0" />
                    <GradientStop Color="#FFF788C7" Offset="0.5" />
                    <GradientStop Color="#FFF570BB" Offset="0.5" />
                     <GradientStop Color="#FFF353AE" Offset="1" />
                </LinearGradientBrush>
            </Setter.Value>
            </Setter>
        </Style>
    </UserControl.Resources>
    <Grid Height="30" Width="800">
        <Button Height="30" HorizontalAlignment="Left" Margin="360,0,0,0" Name="button2" VerticalAlignment="Top" Width="50" Click="b_Click" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" FontSize="10" FontStretch="SemiCondensed" />
        <Button Style="{StaticResource UniqueButton1}" Height="30" HorizontalAlignment="Left" Margin="423,0,0,0" Name="button1" VerticalAlignment="Top" Width="50" Click="b_Click" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" FontSize="10" FontStretch="SemiCondensed" />
    </Grid>
</UserControl>

按钮2是使用

<UserControl.Resources>
        <Style  x:Key="TEST1" TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type Button}}"  >
        </Style>
</UserControl.Resources>

<Button Style="{StaticResource TEST1}" Height="30" HorizontalAlignment="Left" Margin="360,0,0,0" VerticalAlignment="Top" Width="50" Click="button_Click" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" FontSize="10" FontStretch="SemiCondensed"/>

    <UserControl.Resources>
        <Style  x:Key="UniqueButton1" TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type Button}}"  >
            <Setter Property="Background">
                <Setter.Value>
                <LinearGradientBrush EndPoint="0,1">
                    <GradientStop Color="#FFF896CE" Offset="0" />
                    <GradientStop Color="#FFF788C7" Offset="0.5" />
                    <GradientStop Color="#FFF570BB" Offset="0.5" />
                     <GradientStop Color="#FFF353AE" Offset="1" />
                </LinearGradientBrush>
            </Setter.Value>
            </Setter>
        </Style>
    </UserControl.Resources>

<Button Style="{StaticResource UniqueButton1}" Height="30" HorizontalAlignment="Left" Margin="360,0,0,0" VerticalAlignment="Top" Width="50" Click="button_Click" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" FontSize="10" FontStretch="SemiCondensed" />

按钮1是使用

<UserControl.Resources>
        <Style  x:Key="TEST1" TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type Button}}"  >
        </Style>
</UserControl.Resources>

<Button Style="{StaticResource TEST1}" Height="30" HorizontalAlignment="Left" Margin="360,0,0,0" VerticalAlignment="Top" Width="50" Click="button_Click" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" FontSize="10" FontStretch="SemiCondensed"/>

    <UserControl.Resources>
        <Style  x:Key="UniqueButton1" TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type Button}}"  >
            <Setter Property="Background">
                <Setter.Value>
                <LinearGradientBrush EndPoint="0,1">
                    <GradientStop Color="#FFF896CE" Offset="0" />
                    <GradientStop Color="#FFF788C7" Offset="0.5" />
                    <GradientStop Color="#FFF570BB" Offset="0.5" />
                     <GradientStop Color="#FFF353AE" Offset="1" />
                </LinearGradientBrush>
            </Setter.Value>
            </Setter>
        </Style>
    </UserControl.Resources>

<Button Style="{StaticResource UniqueButton1}" Height="30" HorizontalAlignment="Left" Margin="360,0,0,0" VerticalAlignment="Top" Width="50" Click="button_Click" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" FontSize="10" FontStretch="SemiCondensed" />

很明显，按钮1和2不是基于我想要的按钮3。我想克隆按钮3属性，只将背景更改为粉红色。

将你的

BaseButton

从

x:Type

更改为命名按钮，然后在其他

BasedOn

上设置它的

name

，这应该可以做到。

你这么说g

UniqueButton1

样式是否修改默认WPF按钮的背景，而不是修改主题按钮样式的背景？@Jay-我已经更新了我的Q，尝试让事情变得更清楚。基本上，你有一个按钮的主题，你想扩展按钮1和2的默认样式？我不理解而且，你还提到你想在所有状态下继承button1，而button3上的鼠标覆盖。B3是一个主题按钮，我想保留B3的所有属性，除了背景而不是灰色（B3右下角图片）我希望它像B1一样呈粉红色。B2只是在我尝试克隆B3时才显示它不是B3。因此，B1是粉红色的，但所有属性都不像B3那样以蓝色为主题-B1和B2在鼠标悬停时变为蓝色而不是橙色。我如何克隆以蓝色为主题的B3并使背景呈粉红色，或者如何提取所有属性（鼠标悬停、动画速度等）从B3重建样式以匹配B3（粉色背景除外）？另一个想法-是因为

BasedOn=“{StaticResource{x:Type Button}}

使用Expressionblend Button default，而我的usercontrol继承了主题按钮吗？Ie B2是expressionblend，B3是主题。如何具体说明在

{x:Type Button}

中使用的默认按钮？
