Blend 定义按钮模板

一、首先按下图创建一个Silverlight for Windows Phone应用程序.

XAML代码如下

<phone:PhoneApplicationPage xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone" xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:edc="clr-namespace:Microsoft.Expression.Controls;assembly=Microsoft.Expression.Drawing" 
    x:Class="BlendPro.MainPage"
    d:DesignWidth="480" d:DesignHeight="768"
    mc:Ignorable="d"
    SupportedOrientations="Portrait" Orientation="Portrait"
    shell:SystemTray.IsVisible="True">

    <!--LayoutRoot 是放置所有頁面的根資料格-->
    <Grid x:Name="LayoutRoot" Background="Transparent">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition/>
        </Grid.RowDefinitions>

        <!--TitlePanel 包含應用程式的名稱和頁面標題-->
        <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
            <TextBlock x:Name="ApplicationTitle" Text="BlendPro" Style="{StaticResource PhoneTextNormalStyle}"/>
            <TextBlock x:Name="PageTitle" Text="Blend Pro" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
        </StackPanel>
        <Button Content="Button" Grid.Row="1" Height="100" HorizontalAlignment="Left" Margin="154,216,0,0" Name="button1" VerticalAlignment="Top" Width="220" />
    </Grid>

</phone:PhoneApplicationPage>

二、然后打开Blend修改Button

在中间的视图区域中选中Button，接着右击按钮，选择EditTemplate|Edit a Copy。系统将提示您为新模板命名，在本例中命名为BlendButton，并选择模板的归属位置。默认是PhoneApplicationPage，如果想在整个应用程序中重用该模板，则放到App.xaml文件中。单击OK后，Blend会为已有的Button模板复制一份副本，以便对其进行调整，然后打开该模板，进行更改。如图示已经被打开并处于编辑状态，因为它已经列出在Objects and Timeline 窗口的顶部。它的下面是模板内容，其中包含一个Grid，然后是一个名为ButtonBackgroun的Border，最后是一个名为foregroundContainer的ContentControl。

本例中对ButtonBackground Border控件做简单的调整，从而为该按钮做一个圆角边框，它与添加到页面内容周围的边框类似。在Objects and Timeline窗口中，选择ButtonBackground节点，然后再Properties窗口的Brushes区域找到BorderBrush。单击BorderBrush旁的方格，从下拉列表中选择Reset，从而可以显示设置BorderBrush。

将BorderBrush改为纯色画刷，然后使用Color Editor将颜色改为#98AB0000。转到Appearance区域，重置BorderThickness属性。将BorderThickness的所有边都设为10。将ComerRadius设置为20。编辑完成保存。关闭Blend。提示重新载入程序。XAML中代码变为下面内容

<phone:PhoneApplicationPage 
    x:Class="BlendPro.MainPage"

                                            </ObjectAnimationUsingKeyFrames>

    <!--LayoutRoot 是放置所有頁面的根資料格-->
    <Grid x:Name="LayoutRoot" Background="Transparent">

            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>

        <!--TitlePanel 包含應用程式的名稱和頁面標題-->
        <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
            <TextBlock x:Name="ApplicationTitle" Text="BlendPro" Style="{StaticResource PhoneTextNormalStyle}"/>
            <TextBlock x:Name="PageTitle" Text="Blend Pro" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
        </StackPanel>

        <!--ContentPanel - 其他內容置於此-->
        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
            <Button Content="Button" Height="100" HorizontalAlignment="Center" Name="button1" VerticalAlignment="Center" Width="220" Style="{StaticResource BlendButton}" />
        </Grid>
    </Grid>

</phone:PhoneApplicationPage>

到此本示例就完成了，很简单吧。
最后效果如下
