(Xamarin Forms) How to show toolbar when navigate from "Main Page" to any page?

Question

I'm having a problem in Xamarin forms:

I want to open a any page in my app when standing in the main page of app.

Example: Flow of my app:

Main page -> List detail contact -> Detail Contact -> Edit Contact -> ...

I want to navigate from "Main page" to "Detail Contact" without having to go through "List detail contact"

• At AppDelegate.cs, I send a message to "MainPageViewModel.cs"

  MessagingCenter.Send(new AddNewContactEventMessage(), nameof(AddNewContactEventMessage));

• At method Initialize() of "MainPageViewModel.cs", I subcrible message and navigate to "Contact Detail Page":

          MessagingCenter.Subscribe<AddNewContactEventMessage>(this, nameof(AddNewContactEventMessage), message =>
      {
  
          Device.BeginInvokeOnMainThread(async () =>
          {
              try
              {
                  await NavigationService.NavigateAsync(nameof(ContactDetailPage), new ContactManagerNavigationParameters()
                  {
                      ContactId = 0,
                      ManagerId = ActivatedUser.UserId
                  });
              }
              catch (Exception ex)
              {
                  Logger?.Exception(ex);
              }
          });
      });
  

• But when "Detail Contact" is open, Toobar of page is hidden.

• Why Toolbar is hidden? And how to fix it?

Please help me!

Thanks!

Answer 1

Give a title to the page in xaml or from code behind, that shows toolbar .
