I used dotnet to view a big list of thumbnails, containing about 2000
items. If I use WindowsForms10.SysListView32.app3 it is much slower,
specially near end of list, it uses lots of CPU time. But if I use old
SysListView32 ( using SetWindowLong to indirect window procedure) then
it's so much quicker, but stops sending event notifications to my
form, since window procedure is changed.

Anybody Can HELP?

Thanks
