A regular grid holds data in its Data object (a SfTable array of rows with columns).
In a virtual grid the grid does not hold any data at all. All data are only available for a short period during drawing in the volatile data cache. This cache gets emptied once drawing is finished when Garbage collector collects memory (or when you call ResetVolatileData)
The NonVirtualDataCache sample replaces this default volatile data cache and keeps the cached data in this cache until it is manually emptied.
