Subject How to perform async load on grid with IBOQuery

Hello, Iam new with IBO and try to perform large data load into db grid .

I found out that I can use the maxrows property to limit the amount of records fetched from server.


But I just can not figure how to perform the  "load another record on grid scroll", say I scroll down to the maxrows and the data provider should fetch another amount of record for the grid to load which will gives feeling that the grid really has a lot of data.


I saw this kind of feature in some application, for example IBExpert and others, but just don't know how to perform the operation.


The FAQ in IB FAQ has only so little information:


===================


I have about 10 million rows and want to filter them. The result could be also 10 million rows. How can I tell IBO to stop fetching at a position of 1000 rows and if the user scrolls the view down next 1000 will be transferred to the list?

Use the MaxRows property.


===================


Can anybody help me how to solve this.


Thanks.
