ListGrid with progressive loading and selected record

Hi,

It's about a ListGrid with progressive loading. When scrolling down a chunk of data (75 records) have been fetched automatically and shown by the ListGrid. When select a record and than scroll down, e.g. to record #1000 after the data has been fetched the ListGrid jumps back to the selected record.

Without selecting any record upfront scrolling down works fine.

Unfortunately the code is to complex to extract an example. On the show case tried with the "Live Grid" and there it seems to work properly but the data amount there and the delay are less.

Any idea?

Thanks,
