Solution 1

You can only have problems if your List view is trying to hold too many items. The only alternative I can see is using the virtual mode. In this way, you will not keep a copy of all your data in the instance of your list view.

See for explanation and a code sample: http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.virtualmode.aspx[^].
