Question

How can I check if no items “At all” selected from listview?

Thanks.

Answer 1

if( myListView.SelectedItems == null || myListView.SelectedItems.Count == 0 )
{
}

See ListView..::.SelectedItems Property for more info.

EDIT: As per the MSDN documentation:

If no items are currently selected, an
empty
ListView..::.SelectedListViewItemCollection
is returned.

So the null check is not needed in this case and you can simply do:

if( myListView.SelectedItems.Count == 0 )
{
}
