Lot of crashes executing on iPad

[Yeray Julian]

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...
