  Hi Team,

  I have implemented lazy loading of records once the user scroll down using the ‘scrollpositionchanged’ event.

  Is there any direct API which i can use to do the upward lazy load.

  Say if I’m removing the records from the collection that went off from the view range when u scroll down. And when u scroll up bring back those records using a service calls based on scroll.

  Thanks

  You can achieve this by using ODataVirtualCollectionView.
  
  Here is a working example of the same :- http://plnkr.co/edit/tRK0O52inNd7FMrczOB9?p=preview

  However the ODataVirtualCollectionView generates query for fetching records based on standard OData protocol.

  If your web service implements OData protocol you are good to go.

  More info on OData protocol can be found here :- http://www.odata.org/
