GetNextCell in virtual grid

Question

I'm having trouble using the GetNextCell in a virtual grid when selecting rows.  It seems, no matter how many columns I actually have, GetNextCell keeps returning columns which don't exist.  Is there something wrong with the following code?

ArrayList rows = new ArrayList();
GridRangeInfoList selectedRows = 
	this.gridControl1.Selections.GetSelectedRows(false, true);
foreach (GridRangeInfo info in selectedRows )
{
	int top;
	int left;
	if ( info.GetFirstCell(out top, out left) )
	{
		do
		{
			if ( !rows.Contains(top) )
			{
				rows.Add(top);
			}
		} while( info.GetNextCell( ref top, ref left ));
	}
}

Thanks,
Sue

The call to GetSelectedRows will return ranges of type GridRangeType.Row. The GetNextCell type works only with GridRangeType.Cell. What you should do is before the call to 
if ( info.GetFirstCell ...
you should call 
info.ExpandRange(1, 1, RowCount, ColCount);
This will convert the Row range into a Cell range that you can loop through.
