My MultiPageViewModel is a news view, and the number of categories can be changed (for example, news currently has three categories, tab of present , tab of novelties and tab of General News). I want to make a dynamic MultipageViewModel because the app could have new tabs in a near future.

All the tabs contain a ListViewFragme with the same structure (only with a change in the news inside)

The tabs are in the rest request (similar to this)

{Category: "GENERAL",
News: 9
},
{
Category: "ACTUALIDAD",
News: 31
},
{
Category: "NOVEDADES",
News: 10
}

Hi Cristobal,

I will ask this to our developer, but as far as i know it will be very hard and maybe impossible because android need to count the width first which actually done in when initializing, so if you dynamically add new tab, i don't think it is possible.

But i will report back to you and hopefully create a sample for this scenario.

If you want you could tell us your scenario, maybe we can helps give a better, safer alternative and more compliance with standard of each platform.

Best Regards,
Arief

I want to create a MultiPageViewModel that I don't know how many tab have.

Inside of ViewModel I request to webservice the number of tabs should have my MultiPageViewModel.

After, i try to create my NavigationItems with this response.

public override void Navigated(NavigatedParameter parameter)
{
   GetCategories();
   this.UpdateResources();
}

public async void GetCategories()
{
   try
   {
      this.ActivityPresenter.Show("Cargando los datos del socio...", ActivityStyle.LargeIndicator);

      var result = await Repository.GetCategories();
      if (result != null)
      {
         List items = new List();
         foreach (var category in result)
         {
            items.Add(new NavigationItem(string.Format("{0}({1})", category.Category, category.News), typeof(TabsListViewModel)));
         }

         this.Items = items.ToArray();
         this.UpdateResources();
      }
   }
   catch (Intersoft.Crosslight.RestClient.HostUnreachableException)
   {
      this.MessagePresenter.Show(
          "Connection error...");
   }
   catch (Exception ex)
   {
      this.MessagePresenter.Show("Error: 0x0002");
   }
   finally
   {
      this.ActivityPresenter.Hide();
   }
}

Make this is possible?
