Question

I have a ListView which sometimes I need to put around 10000 items in. ListViews don’t really handle this well, and they lock up for a couple of seconds while they sort the items and draw them. If you add the items in individually, it’s even worse, locking up for nearly a minute.

To get around this, I thought I’d try populating the ListView before I need to display it, but unfortunately it has other ideas. It only starts drawing when I turn the panel that contains the ListView visible, making the program hang for a couple of seconds.

Any ideas for how I can eliminate this delay? Or is there another component that’s relatively easy to use that is better at showing large quantities of data?

You need to use the VirtualMode.
