GridConrtol Virtual Mode and / or Virtual Cells

I do not understand if these mechanisms should be used together or only one?

I get the impression that if I want to use Virtual Cells, I should do all the support as an example for Virtual Cells is available at:
https://help.syncfusion.com/wpf/gridcontrol/grid-virtualization

However, for different types of cabinet, other mechanisms and all data styles and validations should be done in

class VirtualizedCellRenderer: GridVirtualizingCellRenderer

for example for e.Style.CellType = "DoubleEdit"; I should do my own TextBox support for the double type.

Should I do it this way?

Hi Krzysztof, 
 
Thank you for using Syncfusion products. 
 
The VirtualMode and VirtualCells are part of Virtualization to populate cell content and cell styles based on indices. The VirtualMode is the process of populating the cell data using virtualization where as the VirtualCells are customized cells that are rendered using virtualization (cells that are rendered in visible range of the Grid). Moreover, in virtualization, the cells will be rendered only when the cell moved to visible range. A customized cell renderer can be added as CellType of VirtualizedGrid (customized DoubleEdit cell as mentioned in your update).
