how to avoid open page already exist on Navigation stack? [duplicate]

Question

I am using Xamarin.forms, Some times user will click twice on same button, I am search away to avoid open same page twice, maybe disable the button after first click will work fine, but i am searching away to avoid open same page if page already exist on Navigation stack.

btnCustomerPage.Clicked += (object sender, EventArgs e) => 
{
 //CustomerPage already Exist on Navigation Stack,So user already open it.
 Navigation.PushAsync(new CustomerPage(); 
};

Answer 1

if (Navigation.NavigationStack.Count == 0 ||
    Navigation.NavigationStack.Last().GetType() != typeof(CustomerPage))
{
    await Navigation.PushAsync(new CustomerPage(), true);
}

var _appNavi = App.NavigationPage.Navigation; if (_appNavi.NavigationStack.Count == 0 || _appNavi.NavigationStack.Last().GetType() != typeof(RankPage)) { await _appNavi.PopToRootAsync(); await _appNavi.PushAsync(new RankPage(), true); } //App.NavigationPage.Navigation.PushAsync(new RankPage()); App.MenuIsPresented = false; – Gettings
