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>
