Resolved: ScrollTo not working with grouped ListView in Xamarin.Forms

Introduction:

Sometimes ListView contains a grouped ItemsSource represented by a custom model class, and we may need to scroll to first item programatically.

Description:

Let's assume 'myListView' is binding with collection object 'EmployeeList<string,Employee>' which is from HomeViewModel.

And if we want to make myListView scroll to first grouped item with
'ScrollTo (object item, object group, Xamarin.Forms.ScrollToPosition position, bool animated)' method, write below code

void ResetAtoZListScroll(object sender, EventArgs e)  

        {  

            if (myListView.ItemsSource != null && _homeViewModel.EmployeeList!=null)  

            {  

                var fisrtItem = myListView.ItemsSource.Cast<object>().FirstOrDefault();  

                myListView.ScrollTo(_homeViewModel.EmployeeList[0][0][0], _homeViewModel.EmployeeList[0], ScrollToPosition.Start, true);  

            }  

  

        }
