How to check whether a cell in a StringGrid is modified

Question

I would like to know how to programatically determine that the data in a cell of the string grid is modified?

I have a string grid in a form. The data for the stringgrid is loading from the Database. If a user modifies the data, I would like to change the data in the database.

Please share the code.

Thanks

The TStringGrid class has an event OnSetEditText which is triggered when user changes data in a cell. Use ACol and ARow in the event handler's parameters to identify which cell has been modified...

procedure TForm1.StringGrid1SetEditText(Sender: TObject; ACol, ARow: Integer;
  const Value: string);
begin
  //Use ACol/ARow to know what has changed, and Value to know what the new data is.

end;
