[Bug] ToolbarItems not shown on shell modal page

[Centurys]

Description

When using Shell template, I would like to use ContentPage.ToolbarItems declaration on content pages to add some commands. ContentPage.ToolbarItems toolbar at the top is not visible on modal page. Is this by design? Can I somehow manually render ContentPage.ToolbarItems with some custom xaml?

Steps to Reproduce

1. Create Shell app.
2. Navigate to modal with code behind: Shell.Current.Navigation.PushModalAsync(new Page2());
3. Add to modal content page Page2 xaml code: Shell.NavBarIsVisible="True"

`

</ContentPage.ToolbarItems>`

Expected Behavior

ContentPage.ToolbarItems is visible

Actual Behavior

None ContentPage.ToolbarItems, Shell.TitleView, Shell.BackButtonBehavior are visible.

This also happens with TitleView - no items appearing - so probably related.

I have this issue but as @bcaceiro said with the TitleView on any page

[rysbilinski]

hi guys. @PureWeen noticed this has been moved to to-do. Is there any timeline on this or a workaround?

I am trying to migrate to shell and this has left me completely stumped with title views (amongst other things). For modal, we have these three issues stated, for tabbed pages we have the issue that the view is not correctly aligned.

[Centurys]

@rysbilinski for modal page as workaruond I did similary looking layout (custom xaml on that page), like toolbar looks not on modal pages.

Anything happening on this issue? It's a bit troublesome to workaround this.

[scastiello]

I have the same issue and the following workaround works for me (on iOS, not tested in Android): Shell.Current.Navigation.PushModalAsync(new NavigationPage(new Page2()));

[barmouta]

thanks @scastiello for the work-around! btw it works on android as well. however, this is really frustrating that, for example, page title has to be manually created with a custom Shell.TitleView for a modal page. I fully embraced shell navigation and have fully re-designed my app in terms of navigation, but now I'm struggling to understand why modal pages can't have a normal <ContentPage Title..... shown on them (without back button of course). Xamarin, can we please have modal pages working the old way?
