Disable specific DataGridCheckBoxColumn cells via ViewModel - wpf

Question

My MVVM project has this ViewModel:
class ListViewModel : ViewModelBase {
public ObservableCollection<ListItemviewModel> Items { ... }
}
class ListItemViewModel : ViewModelBase {
public String Name { ... }
public Boolean IsChecked { ... }
public Boolean IsEnabled { ... }
}
Writing the XAML seemed straightforward:
<DataGrid ItemsSource="{Binding Items}" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="Name" Binding="{Binding Name}" />
<DataGridCheckBoxColumn Header="Is checked" Binding="{Binding IsChecked}" />
</DataGrid>
However, how can I get it so when a ListItemViewModel's IsEnabled property is false the DataGridCheckBoxColumn's cell in that row is disabled?
I tried setting IsReadOnly={Binding IsDisabled} (and adding an IsDisabled property to ListItemViewModel, however to no avail) - and I recognise that would disable/enable the whole column, not individual cells.
I also tried these instructions ( How to disable a cell in a DataGrid while binding to an ObservableCollection ):
<DataGridCheckBoxColumn Header="Is checked" Binding="{Binding IsChecked}" />
<DataGridCheckBoxColumn.CellStyle>
<Style TargetType="DataGridCell">
<Style.Triggers>
<DataTrigger Binding="{Binding IsEnabled}" Value="False">
<Setter Property="IsEnabled" Value="False" />
</DataTrigger>
</Style.Triggers>
</Style>
</DataGridCheckBoxColumn.CellStyle>
However this has no effect and no binding errors are displayed in the Output window.

Answer 1

It turns out the question I linked to ( How to disable a cell in a DataGrid while binding to an ObservableCollection ) was almost-right, but the XAML was somewhat cargo-cultish. The correct XAML is merely:
<DataGridCheckBoxColumn.CellStyle>
<Style TargetType="DataGridCell">
<Setter Property="IsEnabled" Value="{Binding IsEnabled}" />
</Style>
</DataGridCheckBoxColumn.CellStyle>
Sorted!
