Hello,

I was wondering. Is there a possibility to get the row numbers of the rows currently drawn? By that, I mean the rows that are visible to the user in the ArrayCtrl. If I need to derive a class from the ArrayCtrl in order to get them, that is fine. But I'm not sure where to look.

I think it is a good solution because my ArrayCtrl contains 1,000,000 rows, and I want a timer running to update the value of the rows currently in view, by ReadProcessMemory. It is too slow and expensive to update all million rows, so it would be much nicer if I could just update the rows that are visible! Smile

Thanks in advance!
