Hi Boki,
when OnCellFormating is used, working with the grid becomes impossible because cell coloring goes completely wrong (see example.png)
Attached is a little example with source (using VirtualTable component from Devart). Done with Delphi XE and NextDbGrid 5.9.60
Tried to use NextSuite v6 but there is no version for Delphi XE ...
best regards
