Hi,
Good morning,
I have some queries related to ListGrid for progressive loading. Table contains thousands of records and the data page size is set to 50.
Now ListGrid internally calls to database 3 times for getting 150 records in advance.
My Queries:
1. Does it fetches all the records for each database call?
2. Does it truncate the data at server side and send the paginated data to the client?
3. If I uses the ROWNUM for oracle database queries pagination, will it improve the performance?
4. Should I use progressive loading?
Sample DS.xml
Here is other detail:

Thanks
