Problem in rendering SfCardLayout after updating Xamarin.Forms

[Vana Chalikia]

Hello, I have a Xamarin Forms application and I' m using SfCardLayout inside a tabbed page. After updating Xamarin.Forms package to 5.0, I faced a problem. When my view appears for the first time, everything works as expected. But when I change tab and then go back to tab with SfCardLayout (when view appears, I clear my list, call the service again and then add items in the ObservableCollection), the control disappears from view eventhough my property is raised using RaisedPropertyChanged. I face this problem in both Android and iOS platforms and I have also tried to update Syncfusion packages to the latest available. Could you help me, please?

Best regards,

Vana

Hi Vana Chalikia,  

 

Thanks for your patience.  

 

We have analyzed your query and getting empty view when clear and re-added the items dynamically has been resolved by setting the VisibleCardIndex property in CardLayout while adding the items as per below.   

 

Code snippet 

 

 

  <cards:SfCardLayout x:Name="cardLayout" BindableLayout.ItemsSource="{Binding Colors}"  Margin="10"> 

.. 

        </cards:SfCardLayout> 

 

 

 

protected override void OnAppearing() 

        { 

            base.OnAppearing(); 

 

            viewModel.Colors.Clear(); 

 

            viewModel.Colors.Add("Yellow"); 

            viewModel.Colors.Add("Red"); 

            viewModel.Colors.Add("Orange"); 

 

            cardLayout.VisibleCardIndex = cardLayout.Children.Count-1; 

        } 

 

 

Let us know if you have any other queries.
