SfDatagrid Exception when sorting

[Oto Dusek]

Hello,

I modified SfDataGrid, so the datagrid assign new ItemsSource of the datagrid, when it sort rows by clicking on datagrid header.

but i updated nuget packages, now it throws exception on line 31 (see attachment):

ItemsSource = l;

I can fill ItemsSource till I click on the header of the datagrid, then it throws following exception:

Sorry attachment doesn't work, so there is source code

public sealed class EDataGrid : SfDataGrid{
 SortColumnDescriptions scd = new SortColumnDescriptions();
 
 ...
 ...
 
 private void EDataGrid_SortColumnsChanged(object sender, GridSortColumnsChangedEventArgs e)
 {
  SortColumnDescriptions = scd;
 }

 private void EDataGrid_SortColumnsChanging(object sender, GridSortColumnsChangingEventArgs e)
 {
  if (e.AddedItems.Any()) {
   args.SortColumn = e.AddedItems[0].ColumnName;
   args.SortDirection = e.AddedItems[0].SortDirection;
  } else {
   args.SortDirection = ListSortDirection.Ascending;
  }
  foreach (var a in e.AddedItems) {
   scd.Add(a);
  }
  foreach (var a in e.RemovedItems) {
   scd.Remove(a);
  }
  fillDataGridAsync();
 }

 private async void fillDataGridAsync() {
  var l = await rep.GetPageAsync(args);
  ItemsSource = l;

 }
}
