how to get rownumber of currently visible rows?

There may be as many as 2+ million rows of data; the Viewport displays 16 rows at a time.



For the first two scrolls this works as expected but after that it scrolls through the rest of the table without waiting even though rows all display "Loading..." still.



I assume this is happening because getValueAt(0, 0) is trying to get the first rows of the table and after scrolling we no longer have access to them?



My question is how can I get the rownumber of the first VISIBLE row in the table?



Here's a snippet of code:



Dim i

Dim scrollIncr

Dim rowValue

set scrollBar = GDTablePanel.DefaultOverlayable.GTablePanel_4.VScroll

'get position at max scroll...

scrollBarMax = scrollBar.Max

'set maxEntries

log.Message("Max is " & scrollBarMax)

'...and divide by 10 to get the positions to scroll to

scrollSegment = scrollBarMax / 10

i = 0

For i = 1 To 10

    scrollIncr = scrollSegment * i

    log.Message("Scrolling to " & scrollIncr)

    scrollBar.Pos = scrollIncr 

    'need to wait after each scroll until "Loading..." no longer displays in table

    while GTablePanel_4.Viewport.Event_Log.getValueAt(0, 0).toString = "Loading..." 

        aqUtils.Delay(10) 

    Wend

'when "Loading..." no longer displays go on to next scroll action

Next



Thanks!
