What I want to create is a list view that will resize itself in order to show all items. Normally I would use AutoSize, but this won\'t work here. Any other options how can I ma
You will have to manually calculate your desired height and set it as items are added/removed.
Detecting item addition or removal isn't directly supported - so you'll either need to create your own Add/Remove Item calls for clients to call, or handle LVN_INSERTIEM type messages from WndProc.
Auto-sizing controls are usually trickier to use - as you have to track Min/Max sizes, allow room on the owner, and usually add to an awkward usability point for users. Only do something like this if typical solutions (i.e. scroll bars) truly can't work for your need.
