Hello Teoman,

I suppose you are using Simple data-binding which can be used in simple scenarios which does not require complex operations like paging, filtering. etc.  In order to implement these, you should use advanced data-binding through its NeedDataSource event. Check the folowing help article which explains more about this.
Advanced Data-binding (using NeedDataSource event).

Thanks,
Princy.
