How to add a check mark on context menu item?

I have a WPF application with Caliburn Micro. On my DataGrid, I have a context menu with two items, which represent two options two select from. How can I add a check mark on the items?

Here is my code:

    <DataGrid.ContextMenu>
                    <ContextMenu >
                        <MenuItem Header="Treat Invalid Billing Address As Error"  cal:Message.Attach="[Event Click] = [Action TreatInvalidBillingAddressAs('Error')]" />
                        <MenuItem Header="Treat Invalid Billing Address As Warning"  cal:Message.Attach="[Event Click] = [Action TreatInvalidBillingAddressAs('Warning')]" />
                    </ContextMenu>
   </DataGrid.ContextMenu>

...

   public void TreatInvalidBillingAddressAs(string errorOrWarning)
   {
       SelectedFirstEntry.BillingAddressValidation = errorOrWarning;
       Revalidate();
   }

Thanks

As mentioned in the comments to control checked status of the MenuItem you could bind MenuItem.IsChecked property to the BillingAddressValidation property of your view model.

Since this is a property of view model against each row and ContextMenu is defiend against whole DataGrid you can use SelectedFirstEntry item.

<MenuItem ... IsChecked="{Binding SelectedFirstEntry.BillingAddressValidation, Converter={StaticResource ErrorToBoolConverter}}"/>
