Trying to find solution in documentation but can't at all
So, we have SSRM with getRows() method which called after changing filters, column sort
It purges existed rows and replace it with "Loading..." placeholder, so, after server response placeholder rows replaced by response
Also we have refreshServerSide() method which call the same getRows() method but without purging already existed rows (by default) and only replacing it after loading
How i can implement this behaviour (reload rows without purging state) by default for all getRows() actions? (Changing filters, sort)
