示例

1、样式(App.xaml)

&lt;Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 

                         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"    

                         x:Class="Silverlight20.App" 

                         &gt; 

        &lt;Application.Resources&gt; 

                &lt;!--全局样式 - 任何地方都可引用--&gt; 

                &lt;!-- 

                Style - 自定义样式资源。用于修改控件的样式。各个控件的默认样式可参见文档 

                        x:Key - 唯一标识 

                        TargetType - 目标对象类型 

                        Setter - 属性设置器 

                                Property - 需要设置的属性名称 

                                Value - 需要设置的属性值 

                --&gt; 

                &lt;Style x:Key="styleTestApp" TargetType="TextBox"&gt; 

                        &lt;Setter Property="FontSize" Value="24"/&gt; 

                        &lt;Setter Property="Foreground" Value="#0000FF"/&gt; 

                &lt;/Style&gt; 

        &lt;/Application.Resources&gt; 

&lt;/Application&gt;

样式(Style.xaml)

&lt;UserControl x:Class="Silverlight20.Appearance.Style" 

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"    

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"&gt; 

        &lt;StackPanel HorizontalAlignment="Left"&gt; 

                &lt;StackPanel.Resources&gt; 

                        &lt;!--容器内样式 - 所属容器内可引用--&gt; 

                        &lt;!-- 

                        Style - 自定义样式资源。用于修改控件的样式。各个控件的默认样式可参见文档 

                                x:Key - 唯一标识 

                                TargetType - 目标对象类型 

                                Setter - 属性设置器 

                                        Property - 需要设置的属性名称 

                                        Value - 需要设置的属性值 

                        --&gt; 

                        &lt;Style x:Key="styleTestInContainer" TargetType="TextBox"&gt; 

                                &lt;Setter Property="FontSize" Value="24"/&gt; 

                                &lt;Setter Property="Foreground" Value="#00FF00"/&gt; 

                        &lt;/Style&gt; 

                &lt;/StackPanel.Resources&gt; 

                &lt;!--全局样式的应用--&gt; 

                &lt;TextBox Text="我是TextBox（全局样式的应用）" Margin="5" Style="{StaticResource styleTestApp}" /&gt; 

                &lt;!--容器内样式的应用--&gt; 

                &lt;TextBox Text="我是TextBox（容器内样式的应用）" Margin="5" Style="{StaticResource styleTestInContainer}" /&gt; 

                &lt;!--内联样式的应用。内联样式优先级高于全局样式和容器内样式--&gt; 

                &lt;TextBox Text="我是TextBox（内连样式的应用）" Margin="5" Foreground="#FF0000"    Style="{StaticResource styleTestInContainer}" /&gt; 

        &lt;/StackPanel&gt; 

&lt;/UserControl&gt;

2、模板(App.xaml)

                &lt;!--全局模板 - 任何地方都可引用--&gt;

                ContentPresenter - 用于显示继承自 System.Windows.Controls.ContentControl 的控件的内容 

                TemplateBinding - 绑定到所指定的属性名称 

                &lt;ControlTemplate x:Key="templateTestApp" TargetType="Button"&gt; 

                        &lt;Border BorderBrush="Red" BorderThickness="1"&gt; 

                                &lt;Grid Background="{TemplateBinding Background}"&gt; 

                                        &lt;ContentPresenter HorizontalAlignment="Right" /&gt; 

                                &lt;/Grid&gt; 

                        &lt;/Border&gt; 

                &lt;/ControlTemplate&gt; 

模板(Template.xaml)

&lt;UserControl x:Class="Silverlight20.Appearance.Template" 

                        &lt;!--容器内模板 - 所属容器内可引用--&gt; 

                        ControlTemplate - 自定义控件模板。用于修改控件的外观。各个控件的默认模板可参见文档 

                        ContentPresenter - 用于显示继承自 System.Windows.Controls.ContentControl 的控件的内容

                        &lt;ControlTemplate x:Key="templateTestInContainer" TargetType="Button"&gt; 

                                &lt;Border BorderBrush="Red" BorderThickness="1"&gt; 

                                        &lt;Grid Background="{TemplateBinding Background}"&gt; 

                                                &lt;ContentPresenter HorizontalAlignment="Right" /&gt; 

                                        &lt;/Grid&gt; 

                                &lt;/Border&gt; 

                        &lt;/ControlTemplate&gt; 

                        &lt;!--样式内设置模板 - 指定了样式即指定了样式内的模板--&gt; 

                        &lt;Style x:Key="templateTestInStyle" TargetType="Button"&gt; 

                                &lt;Setter Property="Template"&gt; 

                                        &lt;Setter.Value&gt; 

                                                &lt;ControlTemplate TargetType="Button"&gt; 

                                                        &lt;Border BorderBrush="Red" BorderThickness="1"&gt; 

                                                                &lt;Grid Background="{TemplateBinding Background}"&gt; 

                                                                        &lt;ContentPresenter HorizontalAlignment="Right" /&gt; 

                                                                &lt;/Grid&gt; 

                                                        &lt;/Border&gt; 

                                                &lt;/ControlTemplate&gt; 

                                        &lt;/Setter.Value&gt; 

                                &lt;/Setter&gt; 

                &lt;!--全局模板的应用--&gt; 

                &lt;Button Width="200" Margin="5" Content="我是Button（全局模板的应用）" Background="Yellow" Template="{StaticResource templateTestApp}" /&gt; 

                &lt;!--容器内模板的应用--&gt; 

                &lt;Button Width="200" Margin="5" Content="我是Button（容器内模板的应用）" Background="Yellow" Template="{StaticResource templateTestInContainer}" /&gt; 

                &lt;!--样式内模板的应用--&gt; 

                &lt;Button Width="200" Margin="5" Content="我是Button（样式内模板的应用）" Background="Yellow" Style="{StaticResource templateTestInStyle}" /&gt; 

                &lt;!--内联式模板的应用--&gt; 

                &lt;Button Width="200" Margin="5" Content="我是Button（样式内模板的应用）"&gt; 

                        &lt;Button.Template&gt; 

                                &lt;ControlTemplate&gt; 

                                        &lt;Border BorderBrush="Red" BorderThickness="1"&gt; 

                                                &lt;Grid Background="Yellow"&gt; 

                                                        &lt;ContentPresenter HorizontalAlignment="Right" /&gt; 

                                                &lt;/Grid&gt; 

                                        &lt;/Border&gt; 

                                &lt;/ControlTemplate&gt; 

                        &lt;/Button.Template&gt; 

                &lt;/Button&gt; 

3、视觉状态和视觉状态管理器(App.xaml)

                &lt;!--全局视觉状态 - 任何地方都可引用--&gt;

                                                        x:Name - 所属视觉状态组内的指定的视觉状态名称 

                                                --&gt; 

                                                &lt;vsm:VisualState x:Name="MouseOver"&gt; 

                                                        &lt;Storyboard&gt; 

                                                                &lt;ColorAnimation    

                                                                                Storyboard.TargetName="borderBrush"    

                                                                                Storyboard.TargetProperty="Color"    

                                                                                To="Green" 

                                                                                Duration="0:0:3" /&gt; 

                                                        &lt;/Storyboard&gt;

                                                                &lt;Storyboard&gt; 

                                                                        &lt;ColorAnimation    

                                                                                To="Red" 

                                                                &lt;/Storyboard&gt; 

                                                        &lt;/vsm:VisualTransition&gt; 

                                                &lt;/vsm:VisualStateGroup.Transitions&gt; 

                                        &lt;/vsm:VisualStateGroup&gt; 

                                &lt;/vsm:VisualStateManager.VisualStateGroups&gt; 

                                &lt;Border x:Name="border" BorderThickness="10"&gt; 

                                        &lt;Border.BorderBrush&gt; 

                                                &lt;SolidColorBrush x:Name="borderBrush" Color="Red" /&gt;
