[CLOSED] ListView vsReport Search
«
on:
December 03, 2021, 07:23:49 pm »
I wrote the code for the ListView search engine, but it does not mark the items, what do I need to correct?
Code: Pascal
[Select]
[+]
[-]
procedure
TForm1
.
BitBtn4Click
(
Sender
:
TObject
)
;
var
i
,
licznik
:
integer
;
begin
licznik
:
=
0
;
for
i
:
=
0
to
ListView1
.
Items
.
Count
-
1
do
begin
ListView1
.
Items
[
i
]
.
Selected
:
=
false
;
if
pos
(
Edit5
.
Text
,
ListView1
.
Items
[
i
]
.
Caption
)
<>
0
then
begin
ListView1
.
Items
[
i
]
.
Selected
:
=
true
;
licznik
:
=
licznik
+
1
;
end
;
end
;
if
licznik
=
0
then
showmessage
(
'Not Found'
)
;
end
;

listview by default does not show a selection unless focus is set on it.
You can either enable showing the selection:
Code: Pascal
[Select]
[+]
[-]
ListView1
.
HideSelection
:
=
False
;
or set focus on the listview after the search is complete
Code: Pascal
[Select]
[+]
[-]
if
licznik
=
0
then
ShowMessage
(
'Not Found'
)
else
ListView1
.
SetFocus
;
Logged

Thank you, I have one more question, what do I have to change in the code to find each matching element in turn?
