Hi,
 
Everytime you call .Populate first row will be selected, you can avoid this by deleting all selected rows after you call .Populate
 
So:
 
wndReportControl.Populate
 
wndReportControl.SelectedRows.DeleteAll
DoEvents

This is not real virtual mode. This is batch-load mode. It only help to accelerate initial display - but that's happened if user will press END on this first display? He will wait till the last batch will be load? Not very smart...]]> Thu, 26 Mar 2009 23:15:47 +0000 http://forum.codejock.com/forum_posts.asp?TID=13771&PID=47203&title=updating-report-control-in-virtual-mode#47203 <![CDATA[Updating Report control in virtual mode : HiI nave Report control in my...]]> http://forum.codejock.com/forum_posts.asp?TID=13771&PID=47019&title=updating-report-control-in-virtual-mode#47019 Author: alexshemesh

Hi
I nave Report control in my application that should display tens of thousands of rows.
I read those rows from data base , so it takes time to process them.
Ive implemented functionality that processes the records from DB by bunches of 1000 records and adds them to report control asynchronously.
Every time bunch of records processed i add it to underlying storage, call to SetVirtualMode with new number of rows and call to Populate to show new rows.
Everything works but every time i call Populate , Vertical scroll bar jumps back to first row of the list.
The whole idea of my mechanism is to make it possible for user to observe rows that already processed , while rest of rows being added.And its very hard to do when report control always jumps back to first row.
Is there some way to avoid this jump back to first row behavior?
Thanks
