How set a Navigationbar Customization Globally?

[candidodmv]

How can i set a customization globally, instead of to do this in every ?

For exemple, i want set gradient background color on navigation on entire app, not just in page A or B on code behind page:

CustomNavigationPage.SetGradientColors(detailPage, Tuple.Create(startColorNavigationBar, endColorNavigationBar));
CustomNavigationPage.SetGradientDirection(detailPage, CustomNavigationPage.GradientDirection.RightToLeft);

Hello, you need to derive your pages from CustomPage and put the related set gradient methods into its constructor before InitializeComponent()
