如何使 Style.Triggers 触发要应用的不同命名样式 [英] How to make Style.Triggers trigger a different named style to be applied

问题描述

假设我有以下内容:

<Style TargetType="{x:Type TextBox}">
    <Setter Property="BorderThickness" Value="1" />
    <Setter Property="BorderBrush" Value="Gray" />
    <Style.Triggers>
        <Trigger Property="IsFocused" Value="true"> 
            <Setter Property="BorderBrush" Value="Green" />
            <Setter Property="BorderThickness" Value="2" />
        </Trigger>
    </Style.Triggers> 
</Style>

这很好用，这里没有什么太大的问题，但这是一个相当简单的案例.如果我想将 IsFocused 样式状态列为显式样式，会发生什么情况如何将该样式引用为 IsFocused 样式，即

This works fine and there is nothing too much wrong here, but it is a fairly simple case. What happens if I want to have the IsFocused style state listed as a exsplicit style how do reference that style as being the IsFocused style, i.e.

<Style x:key="ActiveStyle" TargetType="{x:Type TextBox}">
    <Setter Property="BorderBrush" Value="Green" />
    <Setter Property="BorderThickness" Value="2" />
</Style>

<Style TargetType="{x:Type TextBox}">
    <Setter Property="BorderThickness" Value="1" />
    <Setter Property="BorderBrush" Value="Gray" />
    <Style.Triggers>
        <Trigger Property="IsFocused" Value="true">
           -- Here I want to reference ActiveStyle and not copy the copy the setters
        </Trigger>
    </Style.Triggers> 
</Style>

推荐答案

我不认为您可以，但是您可以通过这种方式重用样式:

I don't think you can however, you can reuse a style this way :

<Style x:Key="ActiveStyle" TargetType="{x:Type TextBox}">
    <Style.Triggers>
        <Trigger Property="IsFocused" Value="true">
            <Setter Property="BorderBrush" Value="Green" />
            <Setter Property="BorderThickness" Value="2" />
        </Trigger>
    </Style.Triggers>
</Style>

<Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource ActiveStyle}">
    <Setter Property="BorderThickness" Value="1" />
    <Setter Property="BorderBrush" Value="Gray" />
</Style>

我没有看到其他解决方案:(

I don't see another solution :(
