Toolbar not Visible in Xamarin forms?

Posted by at 30 Nov 2017 in Tutorials

Usually, in Xamarin forms we will add below code to have a toolbar on top of the View.
<ContentPage.ToolbarItems >
<ToolbarItem Name="MenuItem1" Order="Primary" Icon="Microsoft.png" Text="Item 1" Priority="0" />
<ToolbarItem Name="MenuItem2" Order="Primary" Icon="Xamarin.png" Text="Item 2" Priority="1" />
But even after adding this code if you are unable to see the Toolbar, then you must need to enable the Navigation bar for the view. You can do this as shown below.
MainPage = new NavigationPage(new MainPage());
Here I enclosed the View call with in a NavigationPage and that does the trick. 
Screenshot of the View.
Hope this helps.
