Hi,

I am facing the following problem, and not sure what is the best solution:

I am using the TDBGrid to display my dataset, but i need to add couple
columns to it which are not from the database.  i will do some calculations
behind, and put the values into these columns, in other words, they are
local to the program.  is there a way to trick the TDBGrid to handle this?
if not, is there any other components that can serve the need other than
writing my own code to creat a look-alike column?

Thanks much.  any suggestions is well appreciated.  Thanks...

Jerri Chiu

Hi Jerri,    
    
    my suggestion is that you could create a calculated field, then to fill
the OnGetText event.

Hi Giuliano,

thanks for the insight, how do i created a calculated field at run time?
since i populate my select, where, order by clauses at run time.  and how
exactly do i use the OnGetText events to populate the values into the
display?

thanks really much...!!
