(22)WPF 控件模板

一、逻辑树和可视化树  

二、模板

　1.创建模板　

    <Window.Resources>
        <ControlTemplate x:Key="ButtonTemplate" TargetType="{x:Type Button}">
            <Border BorderBrush="Orange" BorderThickness="3" CornerRadius="2" Background="Red" TextBlock.Foreground="White" >
                <ContentPresenter RecognizesAccessKey="True" />
            </Border>
        </ControlTemplate>
    </Window.Resources>

    <StackPanel>
        <Button  x:Name="btn1" Template="{StaticResource ButtonTemplate}" Margin="10" Padding="5" >new2</Button>
    </StackPanel>

2.模板绑定

<ContentPresenter RecognizesAccessKey="True" Margin="{TemplateBinding Padding}"/>

3.添加触发器

        <ControlTemplate x:Key="ButtonTemplate" TargetType="{x:Type Button}">
            <Border Name="Border" BorderBrush="Orange" BorderThickness="3" CornerRadius="2" Background="Red" TextBlock.Foreground="White" >
                <ContentPresenter RecognizesAccessKey="True" Margin="{TemplateBinding Padding}"/>
            </Border>
            <ControlTemplate.Triggers>
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter TargetName="Border" Property="Background" Value="DarkRed" />
                </Trigger>
                <Trigger Property="IsPressed" Value="True">
                    <Setter TargetName="Border" Property="Background" Value="IndianRed" />
                    <Setter TargetName="Border" Property="BorderBrush" Value="DarkKhaki" />
                </Trigger>
            </ControlTemplate.Triggers>
        </ControlTemplate>
