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

 1 <Window x:Class="Styles.MultiTrigger"
 2         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 3         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 4         Title="MultiTrigger" Height="300" Width="300">
 5     <Window.Resources>
 6         <Style x:Key="BigFontButton">
 7             <Style.Setters>
 8                 <Setter Property="Control.FontFamily"
 9                         Value="Times New Roman" />
10                 <Setter Property="Control.FontSize"
11                         Value="18" />
12 
13             </Style.Setters>
14             <Style.Triggers>
15                 <MultiTrigger>
16                     <MultiTrigger.Conditions>
17 
18                         <Condition Property="Control.IsFocused"
19                                    Value="True"></Condition>
20 
21                         <Condition Property="Control.IsMouseOver"
22                                    Value="True"></Condition>
23                     </MultiTrigger.Conditions>
24                     <MultiTrigger.Setters>
25                         <Setter Property="Control.Foreground" Value="DarkRed"></Setter>
26                     </MultiTrigger.Setters>
27                 </MultiTrigger>
28             </Style.Triggers>
29         </Style>
30     </Window.Resources>
31 
32     <StackPanel Margin="5">
33         <Button Padding="5"
34                 Margin="5"
35                 Style="{StaticResource BigFontButton}">A Customized Button</Button>
36         <TextBlock Margin="5">Normal Content.</TextBlock>
37         <Button Padding="5"
38                 Margin="5">A Normal Button</Button>
39         <TextBlock Margin="5">More normal Content.</TextBlock>
40         <Button Padding="5"
41                 Margin="5"
42                 Style="{StaticResource BigFontButton}">Another Customized Button</Button>
43     </StackPanel>
44 </Window>
