Binding to a DataGridTemplateColumn using the style used in the DataTemplate?

I have ComboBoxone that makes up DataTemplateand I am unable to bind its property IsEnabledto a property IsReadOnlyon the template DataGridTemplateColumn.

I got the following error in VS output window:

IsReadOnly property not found in 'object' '' ContentPresenter '

ComboBox Style:

<Style TargetType="{x:Type ComboBox}" x:Key="ProficiencyColumnComboBoxStyle">
    <Setter Property="IsEnabled" 
        Value="{Binding RelativeSource={RelativeSource Mode=TemplatedParent},
        Path=IsReadOnly, Converter={StaticResource BooleanOppositeConverter}}" />
</Style>

I believe the problem is with how I point RelativeSourceto identify mine DataGridColumn. I tried:

  • RelativeSource={RelativeSource TemplatedParent}

  • RelativeSource AncestorType={x:Type DataGridColumn}

  • RelativeSource AncestorType={x:Type DataGridTemplateColumn}

I tried adding other stylists to this style, and they take effect, so I know that style and DataTemplateapply to controls.
