I have some grid scenario with > 500,000,000 rows I would like to display in ListView.
If I artificially limit my ListView to display 100,000,000:
_listView.VirtualListSize = _data.Count;
if (_listView.VirtualListSize > 100000000)
_listView.VirtualListSize = 100000000;
Everything works fine (In VirtualMode naturally). When I change my code to:
_listView.VirtualListSize = _data.Count;
if (_listView.VirtualListSize > 100000001)
_listView.VirtualListSize = 100000001;
The ListView display an empty grid... Is this a Microsoft Bug? Where is this coming from? Is this a Win32 ListView limitation? Most importantly, why is this not documented?
