How to update ListView(SfListView) on property change in .NET MAUI?

You can update the Grouping and Sorting of SfListView on property change by using the LiveDataUpdateMode in the .NET MAUI ListView.

C#
Adding GroupDescriptors, SortDescriptors and LiveDataUpdateMode properties of DataSource to ListView.

namespace ListViewMaui
{
    public class Behavior : Behavior<sflistview>
    {
        SfListView listView;
        protected override void OnAttachedTo(SfListView bindable)
        {
            listView = bindable;
            listView.Loaded += Bindable_Loaded;
            base.OnAttachedTo(bindable);
        }

        private void Bindable_Loaded(object sender, ListViewLoadedEventArgs e)
        {
            listView.DataSource.LiveDataUpdateMode = LiveDataUpdateMode.AllowDataShaping;
            listView.DataSource.GroupDescriptors.Add(
                new GroupDescriptor()
                {
                    PropertyName = "ContactName",
                    KeySelector = (object obj1) =>
                    {
                        var item = (obj1 as Contacts);
                        return item.ContactName[0].ToString();
                    }
                });
            listView.DataSource.SortDescriptors.Add(
                new SortDescriptor()
                {
                    PropertyName = "ContactName"
                });
        }
        protected override void OnDetachingFrom(SfListView bindable)
        {
            listView.Loaded -= Bindable_Loaded;
            listView = null;
            base.OnDetachingFrom(bindable);
        }
    }
}

C#
Modifying an item on ListView item tapped using the ItemTappedCommand.

        public ContactsViewModel()
        {
            ChangeItem = new Command(OnChangeItem);
        }
        private void OnChangeItem(object obj)
        {
            if((obj as Syncfusion.Maui.ListView.ItemTappedEventArgs).ItemType == ItemType.GroupHeader)
            {
                return;
            }
            var item = (obj as Syncfusion.Maui.ListView.ItemTappedEventArgs).ItemData as Contacts;
            item.ContactName = "Chan";
        }
