Event CellFormatting in GridView not firing

[Nickolay]

I'm using GridView in Telerik 2017.2

CellFormatting event doesn't firing when my GridView is Updating:

myGrid.TableElement.Update(GridUINotifyAction.StateChanged);

when i'm changing my DataSource:

myGrid.DataSource = currentRaces;

but RowFormatting is firing on this events. What can i do? I need to change color of my cells!
