使用此帖中提供的代码:
lighten background color on button click per binding with converter
我编写了以下代码来更改MouseOver上MahApps Tile的背景:
<local:ColorLightConverter x:Key="colorLightConverter" />
<Style x:Key="aaa" TargetType="mah:Tile">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="{Binding Path=Background.Color, RelativeSource={RelativeSource TemplatedParent}, Mode=OneTime, Converter={StaticResource colorLightConverter}}" />
</Trigger>
</Style.Triggers>
</Style>
彩色光转换器与前面提到的相同,并且在Mahapps Metro Tile上使用了该样式。代码不起作用,因为磁贴在MouseOver上闪烁。另外,在转换器内放置一个断点,我看到它没有到达。
我做错了什么?

我可以通过Tile控件重现问题。它永远不会输入转换器代码,因为TemplatedParent为null。当我将RelativeSource更改为AncestorType={x:Type StackPanel}
时,就像我的情况一样,闪烁消失了,转换器中的断点已经到达。您可以通过添加到绑定FallbackValue=Red
来检查是否是这种情况,在这种情况下,鼠标悬停的颜色将为红色,以便进行错误绑定。
这是我的工作XAML:
<Window.Resources>
<local:ColorLightConverter x:Key="colorLightConverter" />
<Style x:Key="aaa" TargetType="{x:Type Control}">
<Setter Property="Background" Value="White"/>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="{Binding Path=Background.Color, RelativeSource={RelativeSource AncestorType={x:Type StackPanel}}, Converter={StaticResource colorLightConverter},FallbackValue=Red}" />
</Trigger>
</Style.Triggers>
</Style>
</Window.Resources>
<StackPanel Background="DarkGoldenrod">
<mah:Tile Title="Hello!" Style="{StaticResource aaa}"
TiltFactor="2"
Width="100" Height="100"
Count="1" x:Name="tile">
</mah:Tile>
<TextBox Width="100" Height="100" Style="{StaticResource aaa}">Test</TextBox>
</StackPanel>

行。所以这是MainWindow.xaml:
13062 15062 18080 18082
ESTABLISHED 49570 15 0 0
CLOSE_WAIT 0 0 783 493
SYN_RECV 0 0 109 0
TIME_WAIT 0 17 0 0
这是App.xaml

这是颜色转换器代码:
