I store the image in a imagelist, how
to get the image out from it and assign
it to mylistview.column[i].imageindex?

Thanks

chiwan ,
just assign the imagelist to your listview as normal
(or do it on form create event like below)

procedure TForm1.FormCreate(Sender: TObject);
begin
//my imagelist contains 5 images
Listview1.SmallImages := imagelist1;
end;

procedure TForm1.ListView1ColumnClick(Sender: TObject;
  Column: TListColumn);
begin
//check we have correct column
if (column.DisplayName = 'column2')then
 begin
//assign imageindex to image number in imagelist
  Column.ImageIndex := 3;
//  do some sort procedure...
 end;
end;

hope that makes sense ;-)

Hi, Barry
Are you sure column.imageindex using the
image stored in listview.smallimages?
I tried your method, it seems not work,
are there any special requirement for
the image type stored in imagelist?
(I am using standard bmp file).

oh ,it is most likely you need to upgrade commctrl.dll.

you can get update patch which installs newer dll here:
