                                    Mode = ParameterMode.Raw,
                                    Encode = true
                                });
                                de.Click.Success = "onSaveSucess (this.up('grid'))";

Hi @susanz,

Returning false from a DirectEvent's Before handler prevents that DirectEvent.

So, you can do the following:

de.Click.Before = "return ValidateSave(this.up('grid'))";

And return true or false from the ValidateSave function.

Thanks you so much. It works.
