It is possible to make a calculator who calculate the addition of 2 or more cells of a StringGrid and show the result in other cell?

For example:

I have a String grid with 6 cells. I want to show in the 6th cell 1st cell+2nd cell+3rd cell+4th cell+5th cell.

And if the response is 'YES' how can I do this?

Yes, it's certainly possible to write such a program.

Read the values in the cells, convert them to integers, add them, convert the result back to a string, and store that string in the cell designated for the result.

To detect changes to the editable cells, you might wish to handle the OnSetEditText event of the grid control.

  • You're right, Rob Kennedy! this is what i do, and it works: `procedure TForm1.Button1Click(Sender: TObject); var a,b,c: string; d: integer; begin a:=stringgrid1.Cells[1,1]; b:=stringgrid1.Cells[2,1]; c:=stringgrid1.Cells[3,1]; d:=strtoint(a)+strtoint(b)+strtoint(c); stringgrid1.Cells[4,1]:=inttostr(d); end;` – user2714141 Sep 11 '13 at 14:25
