我需要一个按钮根据Window.IsActive
属性更改其样式 - 当窗口失去焦点时,前景色应该改变。
以下代码不会导致任何更改:
<Style TargetType="Button"
x:Key="SYS_Window_Button">
<Setter Property="Foreground"
Value="{StaticResource SYS_Window_Button_Text}" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}">
<ContentPresenter x:Name="MyContentPresenter"
Content="{TemplateBinding Content}"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Margin="0" />
</Border>
<ControlTemplate.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=IsActive}"
Value="False">
<Setter Property="Foreground"
Value="Red" />
</DataTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
有任何想法吗?
