WPF Save/Cancel

The default behaviour of the Save and Cancel buttons enabling/disabling based on IsDirty etc is great but I want the form to close after the user hits Save or Cancel.  Additionally I want the Close button enabled always so othat the form can be closed without changing the data.

The XAML is:
 <Button
                Command="ApplicationCommands.Save"
                CommandTarget="{Binding Source={StaticResource Country}, Path=CommandManager, BindsDirectlyToSource=True}"
                HorizontalAlignment="Left" IsDefault="True">Save</Button>
              <Button
                Command="ApplicationCommands.Undo"
                CommandTarget="{Binding Source={StaticResource Country}, Path=CommandManager, BindsDirectlyToSource=True}"
                HorizontalAlignment="Left" IsCancel="True">Cancel</Button>

I tried adding a Click event as follows:

              <Button
                Command="ApplicationCommands.Undo"
                CommandTarget="{Binding Source={StaticResource Country}, Path=CommandManager, BindsDirectlyToSource=True}"
                Click="CancelButton_Click"
                HorizontalAlignment="Left" IsCancel="True">Cancel</Button>

but the Click event fires before the Command which is no good.

Is there a way of capturing the ApplicationCommand after it has completed, testing the result and then closing the form?
Is there a way of having all of the benefits of codeless updates and modifying the behaviour of the buttns so that they do not disable based on the data?
