Lazy Load content page

Hi,

I use the SfTabView to load content page inside.

It works well however these are very complex page with loading to api in my view model ...

What is the best way to lazy load complex pages?

Now I set the content like this:

My mainview hosts the sftabview:

MainView

        public MainView(IPageService pageService)
        {
            _pageService = pageService;
            InitializeComponent();

            _pageService.CreatePage(typeof(DashboardView), null).ContinueWith((result) =>
            {
                dbView = result.Result as DashboardView;
                dboardTab.Content = dbView.Content;
            });
     }

        private async MainPage_Appearing(object sender, System.EventArgs e)
        {
            await Task.Run(async () =>
            {
                (dbView.BindingContext as DashboardViewModel).Init(null);

                profileView = await _pageService.CreatePage(typeof(ProfileView), null) as ProfileView;
                adminView = await _pageService.CreatePage(typeof(AdminView), null) as AdminView;

                Device.BeginInvokeOnMainThread(async () =>
                {
                    profileTab.Content = profileView.Content;
                    adminTab.Content = adminView.Content;
                });
            }).ConfigureAwait(false);
        }

In this approach my UI is very long to load. I would like to lazy load my pages. 

What are the best practices?

Thanks,

Hi Alexis, 

Greetings from Syncfusion. 

Currently, we do not have the support for Lazy Loading. We have logged the feature request for this.You can track the status of the feature from below link 
 
 
If you have any more specifications/suggestions on this, you can add it as a comment in the portal.    
   
This feature will be available in our upcoming Volume 2 main release which is expected to be rolled out at the end of June 2020.  
  
We suggest a workaround sample to achieve your requirement by assigning content to each tab in the Selection Changed event. Please find the sample from the below link, 
 
Please check with the above sample and let us know if you have any concerns.

Hi Alexis,

Sorry for the inconvenience.

We have not included the feature in our Volume 2 , 2020 main release. We are currently working on this, and due to more architectural changes and to cover more working scenarios it is taking more time than expected. We will include the improvement in our upcoming Volume 3, 2020 main release. Which will be expected to be rolled out on end of September 2020. We are deeply sorry for this delay.

Regards,
Sakthivel P.
