Update individual row in datagrid
«
on:
January 21, 2021, 12:38:08 pm »
Hi All,
I am using sqlite with zeos.
My question is "How can I show changes to a row in a DBGrid without refreshing the whole dataset?"
Test app attached.

Code: Pascal
[Select]
[+]
[-]
procedure
TForm1
.
Button2Click
(
Sender
:
TObject
)
;
var
iTEMP
:
integer
;
begin
if
ZQuery1
.
IsEmpty
then
exit
;
iTEMP
:
=
Random
(
10
)
;
ZQuery1
.
Edit
;
ZQuery1
.
FieldByName
(
'fnCOUNT'
)
.
AsInteger
:
=
iTEMP
;
ZQuery1
.
ApplyUpdates
;
Button2
.
Caption
:
=
iTEMP
.
ToString
;
end
;
if you use only one table in query you can do it this way, but if you use several tables (e.g. via JOIN) then you have to use the
ZUpadateSQL
component
