MultiTrigger的逻辑操作是不是过于简单了，条件间只能为且关系，要是Trigger之间的Setter有不少相同的岂不会产生很多冗余代码

Question

比如默认样式为style1，满足条件A样式设置为style2，满足条件B样式也为style2。

贴一段我的GridSplitter样式代码吧，希望有高人指点一二，本人感激不尽。默认样式为竖直的切分条，设置VerticalAlignment="Top"或VerticalAlignment="Bottom"时为水平的切分条。

	<Style TargetType="{x:Type GridSplitter}">
		<Style.Setters>
			<Setter Property="Background" Value="{StaticResource VerticalSplitterBrushNomal}"/>
			<Setter Property="Width" Value="6"/>
		</Style.Setters>
		<Style.Triggers>
			<Trigger Property="VerticalAlignment" Value="Bottom">
				<Setter Property="Background" Value="{StaticResource HorizontalSplitterBrushNomal}"/>
				<Setter Property="HorizontalAlignment" Value="Stretch"/>
				<Setter Property="Width" Value="auto"/>
				<Setter Property="Height" Value="6"/>
			</Trigger>
			<Trigger Property="VerticalAlignment" Value="Top">
				<Setter Property="Background" Value="{StaticResource HorizontalSplitterBrushNomal}"/>
				<Setter Property="HorizontalAlignment" Value="Stretch"/>
				<Setter Property="Width" Value="auto"/>
				<Setter Property="Height" Value="6"/>
			</Trigger>
			<Trigger Property="IsMouseOver" Value="True">
				<Setter Property="Background" Value="{StaticResource VerticalSplitterBrushHover}"/>
			</Trigger>
			<MultiTrigger>
				<MultiTrigger.Conditions>
					<Condition Property="VerticalAlignment" Value="Bottom"/>
					<Condition Property="IsMouseOver" Value="True"/>
				</MultiTrigger.Conditions>
				<Setter Property="Background" Value="{StaticResource HorizontalSplitterBrushHover}"/>
			</MultiTrigger>
			<MultiTrigger>
				<MultiTrigger.Conditions>
					<Condition Property="VerticalAlignment" Value="Top"/>
					<Condition Property="IsMouseOver" Value="True"/>
				</MultiTrigger.Conditions>
				<Setter Property="Background" Value="{StaticResource HorizontalSplitterBrushHover}"/>
			</MultiTrigger>
		</Style.Triggers>
	</Style>

你好，

WPF的XAML本意不是提供给你写逻辑的地方，如果你想完成更复杂些的逻辑， 你可以在后台代码完成。

如果你想完成“或”的条件，而不是“且”， 你可以用普通的trigger而不是multitrigger。

Answer 2

那您看我那段臃肿的ＸＡＭＬ代码是否可以简化点呢，又或是简化不了了？

Answer 3

没什么可以简化的
