WPF样式——多条件触发器

希望创建多个条件都为真时才激发的触发器，就需要使用MultiTrigger提供的Condition集合

<Window x:Class="Styles.MultiTrigger"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MultiTrigger" Height="300" Width="300">
    <Window.Resources>
        <Style x:Key="BigFontButton">
            <Style.Setters>
                <Setter Property="Control.FontFamily"
                        Value="Times New Roman" />
                <Setter Property="Control.FontSize"
                        Value="18" />

            </Style.Setters>
            <Style.Triggers>
                <MultiTrigger>
                    <MultiTrigger.Conditions>

                        <Condition Property="Control.IsFocused"
                                   Value="True"></Condition>

                        <Condition Property="Control.IsMouseOver"
                                   Value="True"></Condition>
                    </MultiTrigger.Conditions>
                    <MultiTrigger.Setters>
                        <Setter Property="Control.Foreground" Value="DarkRed"></Setter>
                    </MultiTrigger.Setters>
                </MultiTrigger>
            </Style.Triggers>
        </Style>
    </Window.Resources>

    <StackPanel Margin="5">
        <Button Padding="5"
                Margin="5"
                Style="{StaticResource BigFontButton}">A Customized Button</Button>
        <TextBlock Margin="5">Normal Content.</TextBlock>
        <Button Padding="5"
                Margin="5">A Normal Button</Button>
        <TextBlock Margin="5">More normal Content.</TextBlock>
        <Button Padding="5"
                Margin="5"
                Style="{StaticResource BigFontButton}">Another Customized Button</Button>
    </StackPanel>
</Window>
