I have a framework that does not use WCF or RIA services. I have implemented the IndexDataSourceProvider, which works fine for the initial Data retrieval but instead of loading items based on the scroll position it loads items at regular intervals based on QueryRequestInterval.

Hi Ashfaq, 

Are you referring to the IndexDataSourceProvider provided at this post:

http://xceed.com/CS/forums/thread/29497.aspx

 If yes, an IndexDataSourceProvider is provided with the products, you can find more information in the same thread. And you can refer to the RemoteListDataSources sample for an example that you can use. 

If not, can you send us a sample application that shows your implementation so that we investigate this in more detail?  

HI Michel 

I am trying to understand the behavior  of IndexDataSource. Is it supposed to load items based on scroll position or it would load all items (after applying filter) based on QueryInterval and batch size
