Since the last version (3.6), we implemented cell UI Virtualization.
From our website:
“Performance enhancements through cell UI Virtualization, for shorter load times and decreased memory use. With a reference grid containing 10 columns and 100,000 data rows, load time is 3.3 times faster, and the grid uses 55% less memory, compared to previous versions of Xceed Grid for .NET.”

The cells are created (de-virtualized) when you try to access them directly (with cellRow.Cells) or when they become visible to the screen. The grouping and the sorting use only the raw data to recalculate which rows are going to be visible (which will be created). The garbage collector collects all the cells that are not used anymore.
