Problem
How can I implement some caching in a virtual grid?
Cause
Action
If you want to implement some kind of caching, you might override the OnDraw() method. There, you could determine the top row with
| nFirstRow = GetTopRow(); |
and the bottom row of the grid with
| nLastRow = CalcBottomRowFromRect(GetGridRect()); |
You could then check these rows to see if they fit into your current cached page and load/unload the rows from your cache appropriately.
