silverlight - 将前景转换器添加到 xaml 中的 DatagridTextColumn

Question

我正在尝试将转换器添加到 DataGridTextColumn 以根据 xaml 文件中单元格的值转换前景画笔。 DecimalConverter 工作正常并遵循相同的模式。

这是我的xaml...

<UserControl.Resources>
    <y:FixedDecimalConverter x:Key="FixedDecimalConverter" />
    <y:ForegroundValueConverter x:Key="ForegroundValueConverter" />       
</UserControl.Resources>
...
<data:DataGridTextColumn 
    Header="Absolute Return" 
    Binding="{Binding totalAbsoluteReturn.value, Converter={StaticResource FixedDecimalConverter}}"  
    Foreground="{Binding totalAbsoluteReturn.value, Converter={StaticResource ForegroundValueConverter}}" />

这是转换器...

type ForegroundValueConverter() =
    interface  IValueConverter with
        member this.Convert(value, targetType, parameter, culture) = 
             let o: obj = upcast new SolidColorBrush(Colors.Red);
             o

        member this.ConvertBack(value, targetType, parameter, culture) = raise <| NotImplementedException()

...

这是错误信息
