Is it possible to load a list of items into the combobox over an ObservableCollection in the SFDataGrid

Is it possible to load a list of items into the combobox over an ObservableCollection in the SFDataGrid and pre-select one item

I have a ObservableCollection:

ObservableCollection<TrackSection> trackSection = new ObservableCollection<TrackSection>();

        public class TrackSection
        {
            public int SectionID { get; set; }
            public int SectionTrackID { get; set; }
            public int SectionIncr { get; set; }
            public string SectionName { get; set; }
            public string SectionDescription { get; set; }

            public List<string> SurfaceList { get; set; }
           
        }
  
Load Data into the SFDataGrid

   var trackList = await App.Database.GetTrackSectionItemAsync(LoadDB);

            foreach (var TrackList in trackList)
            {
                trackSection.Add(new TrackSection { SectionID = TrackList.SectionID, SectionName = TrackList.SectionName, SectionDescription = TrackList.SectionDescription, SurfaceList = new List<string> { "Item_1", "Item_2", "Item_3" } });
            }

            dataGridSection.ItemsSource = trackSection;
   
The XAML code for the SFGrid:

                                <sfgrid:SfDataGrid.Columns>

                                    <sfgrid:GridNumericColumn IsHidden="False" MappingName="SectionID"/>
                                    <sfgrid:GridNumericColumn IsHidden="False" MappingName="SectionTrackID"/>
                                    <sfgrid:GridNumericColumn IsHidden="False" MappingName="SectionIncr"/>
                                    <sfgrid:GridTextColumn AllowEditing="False" MappingName="SectionName" />
                                    <sfgrid:GridTextColumn AllowEditing="False" MappingName="SectionDescription" />
                                                                    
                                    <sfgrid:GridComboBoxColumn AllowEditing="True"
                                        HeaderText="Surface"                                                               
                                        MappingName="SurfaceList"/>

                                </sfgrid:SfDataGrid.Columns>

When running the code, I have the following error in the Column for the List:

Thanks for any advice and help :)

When I get the Records of the  List from the DataGrid, it Shows me the items:

Hmm, how can I get the Items now correctly displayed?
