本文介绍如何通过XAML在WPF应用中定义统一的按钮样式，包括背景、边框、字体等属性，并实现不同状态下的视觉效果变化。

在Resources下创建一个名称为buttonStyle.xaml文件

在此文件中定义了全局button的样式

代码：

<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:System="clr-namespace:System;assembly=mscorlib">

<Style x:Key="ButtonStyle" TargetType="Button">
<Setter Property="Background" Value="Transparent"/>
<Setter Property="BorderBrush" Value="{StaticResource PhoneForegroundBrush}"/>
<Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/>
<Setter Property="BorderThickness" Value="{StaticResource PhoneBorderThickness}"/>
<Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilySemiBold}"/>
<Setter Property="FontSize" Value="{StaticResource PhoneFontSizeMedium}"/>
<Setter Property="Margin" Value="10,10,10,10"/>
<Setter Property="Width" Value="55"/>
<Setter Property="Height" Value="55"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid Background="Transparent">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver"/>
<VisualState x:Name="Pressed">
<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentContainer">
<DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneButtonBasePressedForegroundBrush}"/>
</ObjectAnimationUsingKeyFrames>

</Storyboard>
</VisualState>
<VisualState x:Name="Disabled">
<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentContainer">
<DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneDisabledBrush}"/>
</ObjectAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="BorderBrush" Storyboard.TargetName="ButtonBackground">
<DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneDisabledBrush}"/>
</ObjectAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="ButtonBackground">
<DiscreteObjectKeyFrame KeyTime="0" Value="Transparent"/>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Border x:Name="ButtonBackground" BorderBrush="Transparent" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" CornerRadius="0" Margin="5">
<ContentControl x:Name="ContentContainer" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" Foreground="{TemplateBinding Foreground}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Padding="{TemplateBinding Padding}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

</ResourceDictionary>

在App.xaml文件的<Application.Resources>

或者普通页面的<phone:PhoneApplicationPage.Resources>

或者用户控件的 <UserControl.Resources> 节点下

添加相应的ResourceDictionary，配置引用buttonStyle.xaml：


<Application.Resources>

<ResourceDictionary>
<local:LocalizedStrings xmlns:local="clr-namespace:DataBoundApp1" x:Key="LocalizedStrings"/>
<SolidColorBrush x:Key="AppAccentBrush" Color="White"/>
<ResourceDictionary.MergedDictionaries>

<ResourceDictionary Source="Resources/buttonStyle.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

</Application.Resources>

注意都要放在ResourceDictionary之间

这样页面中的button可以直接添加样式

<Button x:Name="offlineload"
HorizontalAlignment="Center" VerticalAlignment="Center"
Style="{StaticResource ButtonStyle}"
Click="offlineloadMethod"
>
<Button.Background>
<ImageBrush Stretch="Fill" ImageSource="/Assets/offlinedownload.png"/>
</Button.Background>
</Button>
