Hi,
I have an issue with filter in SfDataGrid control:
1. I load asynchronously data to ObservableCollection for real time.
2. I use ObservableCollection to bind a SfDataPager
3. ItemSource of SfDataGrid is binding by:
ItemsSource="{Binding ElementName=sfDataPager, Path=PagedSource}"
4. Each new data in ObservableCollection I update a Label to show how many data is shown:
lblStatus.Text = $"{(MainGrid.View != null ? MainGrid.View.Records.Count.ToString() : "0")} {Process.Write("Of").ToLower()} {(sfDataPager.PagedSource != null ? sfDataPager.PagedSource.GetInternalList().Count.ToString() : "0")} {Process. Write("Data").ToLower()}";
5. I use FilterChanged event from SfDataGrid to update the same Label in the point "4".
6. The problem is when I show popup of filter in SfDataGrid, I do clic in "Ok" and the application crash with the following message:
System.InvalidOperationException: 'Collection was modified; enumeration operation may not executed.'
7. I been testing and the error happends only when data is binding in ObservableCollection.
