Current cell does not repaint when using InvalidateRange. Grid is in virtual mode. Any suggestions? Thanks

Try calling grid.RefreshRange using the overload that allows you to set forceRefreshCurrentCell to true.

Clay, Thanks. In my early research, the RefreshRange seemed more expensive in terms of CPU utilization than the InvalidateRange so I''ve used the latter. Maybe I can just check is the current cell intersects with my updated range and use the RefreshRange selectively.

Here is the code in RefreshRange. It shows what has to be done to get the currentcell refreshed.
public void RefreshRange(GridRangeInfo range, GridRangeOptions options, bool forceRefreshCurrentCell)
{
	TraceUtil.TraceCurrentMethodInfoIf(Switches.BeginEndUpdate.TraceVerbose, PaneDesc, range);
	if (this.ShouldPrepareUpdate(true))
	{
		Model.ResetVolatileData();
		InternalInvalidate(RangeInfoToRectangle(range));
		if (forceRefreshCurrentCell && range.Contains(CurrentCell.RangeInfo))
			CurrentCell.Refresh();
		Update();
	}
}
