Arrow keys don't work after programmatically setting ListView.SelectedItem

Question

I have a WPF ListView control, ItemsSource is set to an ICollectionView created this way:

var collectionView = 
  System.Windows.Data.CollectionViewSource.Ge         


        

Answer 1

Selecting an item programmatically does not give it keyboard focus. You have to do that explcitly... ((Control)listView1.SelectedItem).Focus()
