1、内联方式--即直接在控件内部利用其属性进行设置

 

<UserControl x:Class="RemoveTextBoxBorder.Page"

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

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

    Width="400" Height="300">

    <Grid x:Name="LayoutRoot" Background="White">

        <Button Content="Button" Height="75" Width="125" BorderBrush="Green" Foreground="Blue" />

    </Grid>

</UserControl>

2、全局方式--在 App.xaml Resources 文件中进行定义

当你在VS2008中创建Silverlight项目中，你会得到一个名叫 "App.xaml"的文件，此文件格式如下:

 

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

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

             x:Class="RemoveTextBoxBorder.App"

             >

    <Application.Resources>

    </Application.Resources>

</Application>

 在此文件中你可以定义自己的样式，定义样式采用如下格式:

 

 

 

<

Style x:Key

=

"

样式名

"

 TargetType

=

"

样式所针对的控件类型

"

>

 

   

<

Setter Property

=

"

控件属性名

"

 Value

=

"

控件属性值

"

 

/>

 

</

Style

>

 在本示例中我们在此文件加入如下样式定义，加入后的App.xaml文件内容如下

 

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

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

             x:Class="RemoveTextBoxBorder.App"

             >

    <Application.Resources>

        <Style x:Key="ButtonStyleOne" TargetType="Button">

            <Setter Property="BorderBrush" Value="Green" />

            <Setter Property="Foreground" Value="Blue" />

            <Setter Property="BorderThickness" Value="4,4,4,4" />

        </Style>

        <Style x:Key="ButtonStyleTwo" TargetType="Button">

            <Setter Property="BorderBrush" Value="Blue" />

            <Setter Property="Foreground" Value="Green" />

        </Style>

    </Application.Resources>

</Application>

然后我们在控件的XAML文件中引用所定义的样式

 

<UserControl x:Class="RemoveTextBoxBorder.Page"

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

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

    Width="400" Height="300">

    <Grid x:Name="LayoutRoot" Background="White">

        <Button Content="Button" Height="75" Width="125" Style="{StaticResource ButtonStyleOne}"  />        

    </Grid>

</UserControl>

 

3、在 C#代码中动态设置控件样式

 为了在代码中引用此控件，我们必须要为此控件命名，在此我们命名为"MyButton"

 

<

Button x:Name

=

"

MyButton

"

 Content

=

"

Button

"

 Height

=

"

75

"

 Width

=

"

125

"

 

/>

     

然后在Page.xaml的code-behind 文件中,在其构造函数中加入如下代码:

   MyButton.Style = Application.Current.Resources["ButtonStyle"] as Style;

 后台代码如下:

     public partial class Page : UserControl

    {

        public Page()

        {

            InitializeComponent();

            MyButton.Style = Application.Current.Resources["ButtonStyleOne"] as Style;

        }

    }
