Hi!

We are using SFDataGrid and SFDataPager and we are finding lot of crashes:
  • If we try to filter the collection and refresh the list, after some time the app crash with a SIGSEGV and close... no way to avoid it....
  • If we use the SfDataPager filter options and do a RefreshFilter, all seems to work great until the filter only returns 2 items: the datagrid don't show them.
  • In iPad, when we try to change the selected Page Using sfDataPager.MoveToNextPage or sdDataPager.MoveToPreviousPage, the call fails with error: "System.InvalidOperationException: No method 'Skip' exists on type 'System.Linq.Queryable'."
  • The same call works perfectly on iPad simulator.

The code we are using to create and initialize the DataGrid and DataPager is:

  sfDataPager = new SfDataPager();
  sfDataPager.PageSize = 11;
           this.CreateBinding(sfDataPager).For(sf => sf.Source).To((ReadingRoomViewModel vm) => vm.MeetingsList).Apply();

           sfDataPager.NumericButtonBackground = UIColor.Blue;
           sfDataPager.NumericButtonCount = 10;
           sfDataPager.TintColor = Colors.WaterBlue();
           sfDataPager.SelectionForeground = Colors.WaterBlue();
           sfDataPager.AutoEllipsisText = "...";
           sfDataPager.AutoEllipsisMode = AutoEllipsisMode.Both;
           

           sfGrid = new SfDataGrid();
           sfGrid.ItemsSource = sfDataPager.PagedSource;

           sfGrid.GridStyle = new CustomDataGridStyle();
           sfGrid.HeaderRowHeight = 35;        
           sfGrid.RowHeight = 45;
           sfGrid.SelectionMode = SelectionMode.None;
           sfGrid.AllowSorting = true;
           sfGrid.ColumnSizer = ColumnSizer.LastColumnFill;
           sfGrid.AutoGenerateColumns = true;

Anything we can do to fix this kind of errors? For now, the control we just buy seems really useless in Xamarin.iOS...
