WPF禁用带样式的Datagrid列

我正尝试更新以前的内置表单以使用样式来帮助清理代码并更好地切换到MVVM。我们有逻辑需要将列标记为只读，直到选中复选框。WPF禁用带样式的Datagrid列

我已经尝试绑定到复选框本身，但收到绑定错误，说它找不到复选框。

IsReadOnly="{Binding ElementName=ckbPerUnitType, Path=IsChecked, Converter={StaticResource BoolInv}, ConverterParameter=True}"

我已经尝试绑定到父用户控件数据上下文，该复选框被绑定到。我收到一个错误，说明无法找到绑定参考的来源。

IsReadOnly="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType=UserControl}, Path=DataContext.RentAdj.blnIsDifferentForType, Converter={StaticResource BoolInv}, ConverterParameter=True}"

我不知道我缺少什么。

这里是因为这是转换器，两个

<ValueConversion(GetType(Boolean), GetType(Boolean))> _ 
Public Class BooleanInverseConverter 
    Implements IValueConverter 
    ''' <summary> 
    ''' Converter to Compare the Inverse of a Boolean 
    ''' </summary> 
    ''' <param name="value">Boolean you wish to compare</param> 
    ''' <param name="targetType"></param> 
    ''' <param name="parameter">Boolean to determine if the value needs to be inverted</param> 
    ''' <param name="culture"></param> 
    ''' <returns></returns> 
    ''' <remarks></remarks> 
    Public Function Convert(ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.Convert 
     Dim v As Boolean = DirectCast(value, Boolean) 
     If CBool(parameter) = True Then v = Not v 
     Return v 
    End Function 
    Public Function ConvertBack(value As Object, targetType As Type, parameter As Object, culture As Globalization.CultureInfo) As Object Implements IValueConverter.ConvertBack 
     Throw New Exception("Not Implemented") 
    End Function 
End Class

用在研究不同的问题转换器的代码，我碰到this答案，它actaully解决了我的问题。这里是工作解决方案

<CheckBox x:Name="ckbPerUnitType" /> 
.... 
IsReadOnly="{Binding Source={x:Reference ckbPerUnitType}, Path=DataContext.RentAdj.blnIsDifferentForType, Converter={StaticResource BoolInv}, ConverterParameter=True}"
