WPF Listbox binding: SelectedItem not setting
12,636
You need to bind to the SelectedProperty
:
<ListBox ItemsSource="{Binding Properties}"
DisplayMemberPath="Name"
SelectedItem="{Binding SelectedProperty}" />

I have a ListBox simplified to the following XAML
<ListBox ItemsSource="{Binding Properties}" DisplayMemberPath="Name" SelectedItem="SelectedProperty" />
and in my ViewModel:
private List<Property> propertyList; private Property selectedProperty; public List<Property> Properties { get { return propertyList; } set { propertyList = value; NotifyPropertyChanged("Properties"); } } public Property SelectedProperty { get { return selectedProperty; } set { NotifyPropertyChanged("SelectedProperty"); selectedProperty= value; } }
My List box populates fine, but no matter what I try I cannot seem to get the SelectedProperty to update when I select an item in my list box. I have tried switching it all around to use
ObservableCollection
rather thanList
and adding an Event handler for CollectionChanged, but this has not worked.I am sure I am missing something stupid, and cannot see the wood for the trees. I am reaching the end of my tether and need someone to step in and help.
