Binding Listbox ItemsSource to property of ViewModel in DataContext in WPF
- by joshperry
I have a simple ViewModel like:
public class MainViewModel {
public MainViewModel() {
// Fill collection from DB here...
}
public ObservableCollection<Projects> ProjectList { get; set; }
}
I set the window's DataContext to a new instance of that ViewModel in the constructor:
public MainWindow() {
this.DataContext = new MainViewModel();
}
Then in the Xaml I am attempting to bind the ItemsSource of a ListBox to that ProjectList property.
Binding just ItemsSource like so doesn't work:
<ListBox ItemsSource="{Binding ProjectList}" ItemTemplate="..." />
But if I first rebase the DataContext this works:
<ListBox DataContext="{Binding ProjectList}" ItemsSource="{Binding}" ItemTemplate="..." />
Shouldn't the first method work properly? What am I doing wrong?
