                        InvalidStyle="{StaticResource InvalidEntryStyle}"
                        ValidStyle="{StaticResource ValidEntryStyle}" />
                </Entry.Behaviors>
            </Entry>
            <Label
                FontSize="15"
                HorizontalOptions="Start"
                HorizontalTextAlignment="Start"
                IsVisible="{Binding IsNotValid, Source={x:Reference EmailValidator}}"
                Text="Invalid Email"
                TextColor="Red"
                VerticalOptions="Start"
                VerticalTextAlignment="Start" />
