DialogHost custom labels

   Hi
I am in need of some custom labels in my dialog ( Pass,Fail,Cancel)

And I know I can achieve that with the following

var result = await _dialogManager.ShowDialogAsync(mod, new[] {"Pass", "Fail", "Cancel"});

where mod is my custom view model.

What I can't work out how to do is to be able to enable/disable the buttons within the view model.

Is this the best way to do this or is there another way?

When I tried using custom commands

 var commands = new List<IDialogUICommand<DialogResult>>();
            _passCommand = new DialogUICommand<DialogResult>("Pass", DialogResult.Ok, true, false);
            commands.Add(_passCommand);
            _failCommand = new DialogUICommand<DialogResult>("Fail", DialogResult.No, false, false);
            commands.Add(_failCommand);
            var closeCommand = new DialogUICommand<DialogResult>("Cancel", DialogResult.Cancel, false, true);
            commands.Add(closeCommand);
var result = await _dialogManager.ShowDialogAsync(mod, commands);

the labels did not show correctly on the buttons. Is this the better way, and if so what have I done wrong with the labels

thanks
