Question

更新：使用Expression Blend 3

我正在尝试设计IsPressed＆amp; amp; IsEnabled（false）属性触发WPF应用程序中的一类按钮。

这是一个带有Button的UserControl，使用样式...

<UserControl
    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"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    x:Class="Kiosk.ButtonTest"
    x:Name="UserControl">

    <Grid x:Name="LayoutRoot">
        <Button HorizontalAlignment="Left" Style="{DynamicResource BlueButton}" VerticalAlignment="Top" Width="155" Content="Button" Height="52.9"/>
    </Grid>
</UserControl>

这是风格片段......

   <!-- Blue Button -->
   <Style x:Key="BlueButton" TargetType="{x:Type Button}">
    <Style.Triggers>
        <Trigger Property="IsMouseOver" Value="True">
            <Setter Property="Background" Value="{DynamicResource BlueGradient3}"/>
        </Trigger>
        <Trigger Property="IsEnabled" Value="False">
            <Setter Property="Background" Value="{DynamicResource DarkGradient1}"/>
            <Setter Property="BorderBrush" Value="{DynamicResource BlueGradient3}"/>
        </Trigger>
        <Trigger Property="IsPressed" Value="True">
            <Setter Property="Background" Value="{DynamicResource DarkGradient1}"/>
            <Setter Property="BorderBrush" Value="{DynamicResource BlueGradient1}"/>
        </Trigger>
    </Style.Triggers>
    <Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/>
    <Setter Property="Background" Value="{DynamicResource BlueGradient1}"/>
    <Setter Property="BorderBrush" Value="{DynamicResource BlueGradient2}"/>
    <Setter Property="Foreground" Value="White"/>
    <Setter Property="HorizontalContentAlignment" Value="Center"/>
    <Setter Property="VerticalContentAlignment" Value="Center"/>
    <Setter Property="TextBox.TextAlignment" Value="Center"/>       
    <Setter Property="FontFamily" Value="Trebuchet MS"/>
    <Setter Property="FontSize" Value="18"/>
    <Setter Property="Effect" Value="{DynamicResource KioskStandardDropShadow}" />
</Style>
<LinearGradientBrush x:Key="BlueGradient1" EndPoint="0.5,1" StartPoint="0.5,0">
    <GradientStop Color="#FF3FA2FD" Offset="0"/>
    <GradientStop Color="#FF014782" Offset="1"/>
</LinearGradientBrush>
<LinearGradientBrush x:Key="BlueGradient2" EndPoint="0.5,1" StartPoint="0.5,0">
    <GradientStop Color="#FF014782" Offset="0"/>
    <GradientStop Color="#FF3FA2FD" Offset="1"/>
</LinearGradientBrush>
<LinearGradientBrush x:Key="BlueGradient3" EndPoint="0.5,1" StartPoint="0.5,0">
    <GradientStop Color="#FF014782" Offset="1"/>
    <GradientStop Color="#FF0B2135" Offset="0"/>
</LinearGradientBrush>
<LinearGradientBrush x:Key="DarkGradient1" EndPoint="0.5,1" StartPoint="0.5,0">
    <GradientStop Color="#FF2A2A2A" Offset="0"/>
    <GradientStop Color="#FF474747" Offset="0.478"/>
    <GradientStop Color="#FF323232" Offset="0.487"/>
    <GradientStop Color="Black" Offset="1"/>
    <GradientStop Color="#FF282828" Offset="0.681"/>
</LinearGradientBrush>
    <!-- Regular Drop Shadow --> 
    <DropShadowEffect x:Key="KioskStandardDropShadow" Opacity="0.6" BlurRadius="10" ShadowDepth="5" Direction="308"/>
<!-- fragment end -->

默认和鼠标悬停更改工作正常，但isEnabled为false且isPressed为true仍显示Button默认颜色。

我做错了什么？

我在研究了http://mark-dot-net.blogspot.com/2007/07/creating-custom-wpf-button-template-in.html ...

的代码后修复了它

这是我最终的结果，效果很好。

<!-- Blue Button -->
<Style x:Key="BlueButton" TargetType="{x:Type Button}">
<Setter Property="OverridesDefaultStyle" Value="True"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Border Name="border" 
                    BorderThickness="2"
                    Padding="4,2" 
                    BorderBrush="{DynamicResource BlueGradient2}"
                    CornerRadius="5" 
                    Background="{TemplateBinding Background}">
                    <Grid >
                    <ContentPresenter 
                                HorizontalAlignment="Center" 
                                VerticalAlignment="Center" 
                                Name="content"/>
                    </Grid>
                </Border>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsMouseOver" Value="True">
                        <Setter Property="Background" Value="{DynamicResource BlueGradient3}"/>
                    </Trigger>
                    <Trigger Property="IsEnabled" Value="False">
                        <Setter Property="Background" Value="{DynamicResource DarkGradient1}"/>
                        <Setter Property="BorderBrush" Value="{DynamicResource BlueGradient3}"/>

您需要更换ControlTemplate以更改按钮的背景颜色。

以下是我从MSDN复制的，与您的代码配合得很好您可以将特定覆盖合并为此样式。

修改要使以下样式正常工作，您需要从Microsoft下载Styling with Control Templates Sample。如果您从示例中包含Button.xaml和Shared.xaml，则以下样式应该起作用，因为这两个文件包含下面的XAML列出的所有StaticResoruces。我正在使用Visual Studio 2008进行测试。

以下是我控制用户控制的方式：

<UserControl x:Class="ButtonPressed.Views.KioskButton" 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" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" Height="300" Width="300"> <UserControl.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Button.xaml"> </ResourceDictionary> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </UserControl.Resources> <Grid> <Button HorizontalAlignment="Left" VerticalAlignment="Top" Width="155" Content="Button" Height="52.9"/> </Grid> </UserControl>

以下是Button.xaml的按钮样式的一部分：

<Style TargetType="Button"> <Setter Property="SnapsToDevicePixels" Value="true"/> <Setter Property="OverridesDefaultStyle" Value="true"/> <Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/> <Setter Property="MinHeight" Value="23"/> <Setter Property="MinWidth" Value="75"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Border x:Name="Border" CornerRadius="2" BorderThickness="1" Background="{StaticResource NormalBrush}" BorderBrush="{StaticResource NormalBorderBrush}"> <ContentPresenter Margin="2" HorizontalAlignment="Center" VerticalAlignment="Center" RecognizesAccessKey="True"/> </Border> <ControlTemplate.Triggers> <Trigger Property="IsKeyboardFocused" Value="true"> <Setter TargetName="Border" Property="BorderBrush" Value="{StaticResource DefaultedBorderBrush}" /> </Trigger> <Trigger Property="IsDefaulted" Value="true"> <Setter TargetName="Border" Property="BorderBrush" Value="{StaticResource DefaultedBorderBrush}" /> </Trigger> <Trigger Property="IsMouseOver" Value="true"> <Setter TargetName="Border" Property="Background" Value="{StaticResource DarkBrush}" /> </Trigger> <Trigger Property="IsPressed" Value="true"> <Setter TargetName="Border" Property="Background" Value="{StaticResource PressedBrush}" /> <Setter TargetName="Border" Property="BorderBrush" Value="{StaticResource PressedBorderBrush}" /> </Trigger> <Trigger Property="IsEnabled" Value="false"> <Setter TargetName="Border" Property="Background" Value="{StaticResource DisabledBackgroundBrush}" /> <Setter TargetName="Border" Property="BorderBrush" Value="{StaticResource DisabledBorderBrush}" /> <Setter Property="Foreground" Value="{StaticResource DisabledForegroundBrush}"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style>
