I have an issue with VirtualQueryableCollectionView.

In my application I used VirtualQueryableCollectionView which acts as a datasource to Rad DataGrid with page size 50, On scrolling it takes another bunch of 50 record from data base and displays in datagrid but after scrolling it takes 50 record from database but UI display previous 50 records in blank lines and next data fetched from database will get display properly on UI(as show in attached Image)

Please provide help on this.
