Here''s my basic situation. I have a virtual grid, where the data collection serving the grid is being updated in real time behind the scenes. However, only certain fields of each row are updated. I know I can call grid.ResetVolotileData() to force the virtual grid to call QueryCellInfo for all of the cells currently visible on the grid. But that would be a waste if only a handful of those cells actually changed. That said, is there a way to invalidate only certain cells so that QueryCellInfo is only called for those cells? It seems like ChangeCells is not meant for virtual mode grids, correct me if I''m wrong.

To invalidate only certain cells, you can call grid.RefreshRange passing in the range of cells to be refeshed.
