Q: How to edit a calculated field in a DBGrid

I have a number which evaluates via the OnCalcluate Event to so some
checkboxes in a DbGrid. I want to do the way back too: Editing the
Checkboxes and storing the calculated number in the table. But as the
calclualted fields are readonly I am stuck.

Any hints availiable?

Thank you!
