I try to test the DataGrid with a ObjectList (the data is valid) then I got a NullReferenceException, how can I find this ?
bei System.Windows.Controls.DataGrid.OnItemsSourceChanged_BeforeVisualUpdate(IEnumerable oldValue, IEnumerable newValue)
bei Windows.UI.Xaml.Controls.ItemsControl.OnItemsSourceChanged(IEnumerable oldValue, IEnumerable newValue)
bei Windows.UI.Xaml.Controls.ItemsControl.OnItemsSourceChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
