Hide Tab From Tabbed Page XAML

Question

Hi Guys,

I have a Xamarin.Forms Project With a Navigation page witch contains a TabbedPage with 3 ContentPages Inside Descibed in a XAML File.

But depending on a bool I have to hide or not a tab of the tabbedPage.
I used the IsVIsible property with a bindable variable But it just hides the content of the page from me but does not remove the tab from the page tabbed from me, have a solution to remove the tab from user view.

<ContentPage Title="{x:Static res:UI.SettingTabPreferenceLabelKey}" IsVisible="{Binding IsFromLoginWithoutConnexion}">  

Thank you for your answers

Hello,​

Welcome to our Microsoft Q&A platform!

1.The TabbedPage class doesn't provide a property or method to hide the tab. For this function, try to define the tabbedPage's children using the Remove and Insert method.

   TabbedPage theTabbedPage = App.Current.MainPage as TabbedPage;  
   public void HideTab(int index)  
   {  
       if (index < theTabbedPage.Children.Count)  
       {  
           theTabbedPage.Children.RemoveAt(index);  
       }  
   }  
   public void AddTab(int index)  
   {  
       // Adjust this page as you want  
       if (!theTabbedPage.Children.Contains(thePage))  
       {  
           theTabbedPage.Children.Insert(index, thePage);  
       }  
   }  

2.If you want to change the template of the application, you could create two tabbedPages to display the different status. Change the App.Current.MainPage when the bool property is changed.

   public partial class App : Application  
   {  
       public App()  
       {  
           InitializeComponent();  

           if (_value)  
           {  
               MainPage = new TabbedPage1();  
           }  
           else  
           {  
               MainPage = new TabbedPage2();  
           }  
       }  
       ...  
   }
