方法一、定义在控件内部
1 <Canvas Background="Red" Height="100" HorizontalAlignment="Left" Margin="90,80,0,0" Name="canvas1" VerticalAlignment="Top" Width="200" />
方法二、定义在控件外部
1 <UserControl.Resources> 2 <Style x:Key="StyleName" TargetType="Canvas"><!--x:Key是指样式的名称--> 3 <Setter Property="Background" Value="Red"></Setter> 4 </Style> 5 </UserControl.Resources> 6 <Grid x:Name="LayoutRoot" Background="White"> 7 <Canvas Style="{StaticResource StyleName}" Height="100" HorizontalAlignment="Left" Margin="90,80,0,0" Name="canvas1" VerticalAlignment="Top" Width="200" /><!--让Canvas的样式指定为静态的资源--> 8 </Grid>
要想让外部样式应用于所有相同类型的控件，只要去掉资源中的样式名称，则TargetType指定的控件都将应用该样式
1 <UserControl.Resources> 2 <Style TargetType="Canvas"> 3 <Setter Property="Background" Value="Red"></Setter> 4 </Style> 5 </UserControl.Resources> 6 <Grid x:Name="LayoutRoot" Background="White"> 7 <Canvas Height="100" HorizontalAlignment="Left" Margin="90,80,0,0" Name="canvas1" VerticalAlignment="Top" Width="200" /> 8 <Canvas Height="100" HorizontalAlignment="Left" Margin="121,188,0,0" Name="canvas2" VerticalAlignment="Top" Width="200" /> 9 </Grid>
方法三、定义全局的样式
将样式放到App.xaml文件的资源定义里
1 <Application.Resources> 2 <Style TargetType="Canvas"> 3 <Setter Property="Background" Value="Red"></Setter> 4 </Style> 5 </Application.Resources>
