Strange behavior, not all ComboBoxes are set like they should when scrolling down

I tried it with a ComboBox cell and there is something strange going on. All ComboBoxes on rows that are visible on load are set but the next 13 are not. Then the rest of my 50 rows are set. Very strange! That's with ComboBox ItemsSource RelativeSource Binding.

<DataBox Margin="10"
                 Items="{CompiledBinding Projects}"
                 CanUserResizeColumns="True"
                 GridLinesVisibility="All">
...

<DataBoxTemplateColumn Header="Manager"
                                       Width="*">
                    <DataTemplate DataType="model:Project">
                        <Panel Background="Transparent">
                            <ComboBox
                                Items="{Binding Path=DataContext.Managers, 
                                        RelativeSource={RelativeSource AncestorType={x:Type Window}}}"
                                SelectedItem="{CompiledBinding Manager}"
                                BorderThickness="0"
                                HorizontalAlignment="Stretch" />
                        </Panel>
                    </DataTemplate>
                </DataBoxTemplateColumn>

With Binding to Tag Property it's working as expected.

<DataBox x:Name="DataBox" Margin="10"
                 Items="{CompiledBinding Projects}"
                 CanUserResizeColumns="True"
                 GridLinesVisibility="All"
                 Tag="{CompiledBinding Managers}">
...

<DataBoxTemplateColumn Header="Manager"
                                       Width="*">
                    <DataTemplate DataType="model:Project">
                        <Panel Background="Transparent">
                            <ComboBox
                                Items="{CompiledBinding #DataBox.Tag}"
                                SelectedItem="{CompiledBinding Manager}"
                                BorderThickness="0"
                                HorizontalAlignment="Stretch" />
                        </Panel>
                    </DataTemplate>
                </DataBoxTemplateColumn>

Multi Selection Support

first of thanks for this Control it would be a prefect replacement for Avalonia DataGrid 'well it least for me!'
but can u add support for Multi Selection with ability to bind For the SelectedItems I've added Extension to support this but it would be great to have this Built-in
my code idk if it's the best way to do it! but it's work for me.

public class DataBoxExtended : DataBox.DataBox, IStyleable {
 public static readonly DirectProperty<DataBoxExtended, IList> SelectedItemsProperty =
     AvaloniaProperty.RegisterDirect(nameof(SelectedItems), o => o.SelectedItems,
         (Action<DataBoxExtended, IList>)((o, v) => o.SelectedItems = v), defaultBindingMode: BindingMode.TwoWay);

 public static readonly DirectProperty<DataBoxExtended, bool> IsSingleSelectProperty =
     AvaloniaProperty.RegisterDirect(nameof(IsSingleSelect), o => o.IsSingleSelect,
         (Action<DataBoxExtended, bool>)((o, v) => o.IsSingleSelect = v), defaultBindingMode: BindingMode.TwoWay);

 private bool _isSingleSelect;
 private IList _selectedItems;

 public DataBoxExtended() {
     _isSingleSelect = false;
     _selectedItems = null;
     RowsPresenter = new DataBoxRowsPresenter();
 }

 private protected DataBoxRowsPresenter RowsPresenter { get; set; }

 public IList SelectedItems {
     get => _selectedItems;
     set => SetAndRaise(SelectedItemsProperty, ref _selectedItems, value);
 }

 public bool IsSingleSelect {
     get => _isSingleSelect;
     private protected set => SetAndRaise(IsSingleSelectProperty, ref _isSingleSelect, value);
 }

 Type IStyleable.StyleKey => typeof(DataBox.DataBox);

 protected override void OnApplyTemplate(TemplateAppliedEventArgs e) {
     base.OnApplyTemplate(e);
     //var cm = this.FindControl<ContextMenu>("Cm");
     RowsPresenter = e.NameScope.Find<DataBoxRowsPresenter>("PART_RowsPresenter");
     RowsPresenter.SelectionMode = SelectionMode.Multiple;
     RowsPresenter.SelectionChanged += (_, _) => {
         SelectedItems = RowsPresenter.SelectedItems;
         IsSingleSelect = SelectedItems is { Count: 1 };
         SelectionChanged?.Invoke(null, EventArgs.Empty);
     };
 }

 public event EventHandler SelectionChanged;
}
