What is the "second" cell? A grid is two-dimensional. You mean "second cell in first row" or "second cell in third column"?

Good day wp.
I mean whichever row I have selected (I have goRowHighlight enabled) second cell in that row (horizontal, second from left) will be read. Thank you wp.

Hi
Connect the onSelectCell event of your stringGrid with the following procedure:
Code: Pascal
[Select]
[+]
[-]
procedure
TForm1
.
StringGrid1SelectCell
(
Sender
:
TObject
;
aCol
,
aRow
:
Integer
;
var
CanSelect
:
Boolean
)
;
var
s
:
string
;
begin
s
:
=
StringGrid1
.
Cells
[
1
,
Arow
]
;
showMessage
(
s
)
;
end
;

Or just do something like:
Code: Pascal
[Select]
[+]
[-]
if
MyGrid
.
Row
>
=
0
then
Value
:
=
MyGrid
.
Cells
[
1
,
MyGrid
.
Row
]
