I am trying to use listbox and make something like Windows Explorer. I am loading in 8000 items, so the virtualizing is very helpful. I wish scrolling wasn't so clunky. But here is the issue. Is there a way a way to do like Windows Explorer and load the image for the items when they appear virtualized or after the fact? You see, if I wait for 8000 items to make a call to the backend and get their icons, it will take forever. So I need to get the icons for each item in the listbox when I need it. But I can't figure out how to do that. Do you have any samples? I hope that makes sense. I am sure you have seen it where the items in a list appear with place holders and then the images come in as they are loaded.
