How is this possible?
I want to populate/depopulate a ListView (or something that looks like it/provides the same basic functionality of a ListView with columns and items)
very quickly.
For example adding/removing 200,000 items in less than half a second.
It should be possible... I don't know why it's so slow by default (...technology... we can render amazing 3d things lightning quick but the .NET listview makes us wait 30 seconds to populate...)
BeginUpdate() and EndUpdate() makes the listView finish in about 10-15 seconds on my computer.
There is a program out there that does this instant updating, it is freeware but not open source. It's a desktop file search program called Everything by VoidTools.
Found something on virtual mode
